When accessing Outlook Calendar via a browser shortcut on your iPad, the system treats it like a fresh browser session. This means you’ll be prompted to sign in each time, especially if session cookies expire or aren’t retained.

🧭 Key Points

• Browser shortcuts open Outlook Calendar as if you’re accessing it directly from Safari or Chrome
• Due to security and session handling, repeated sign-ins are expected behavior
• This does not happen when using the Outlook app, which maintains your login session securely

✅ Recommended Solution

• Install the Microsoft Outlook app from the App Store
• Sign in once, and your calendar will remain accessible without repeated prompts
• The app also offers smoother integration with notifications, scheduling, and Teams meetings

If a calendar you previously added is no longer visible, the issue may be related to display settings or browser instability. Try the following steps to restore visibility:

🧭 Troubleshooting Checklist

1. Use the “Show All” Button

• Go to the Calendar screen
• Click “Show All” in the lower-left corner
• Check if the names of added calendars reappear

2. Re-select the Calendar

• If names appear, click the name of the person whose calendar you want to view
• Confirm if their calendar loads correctly

3. Clear Your Browser Cache

• If names don’t appear after clicking “Show All,” your browser may be unstable
• Clear your browser’s cache (note: this will delete browsing data)
• Restart the browser and try again

If the issue persists, consider accessing the calendar from a different browser or device, or contact your IT support team for further assistance.

If the navigation pane or “Add Calendar” option is missing in Outlook Calendar, it may be due to a collapsed sidebar or display settings. You can restore visibility by following these steps.

🧭 How to Display the Navigation Pane in Outlook Calendar

1. Go to Outlook Calendar
2. Click the ≡ (menu icon) in the upper-left corner of the screen, next to the Home button
3. This should expand the sidebar and reveal:
   • A mini calendar
   • The “Add Calendar” option
   • Other navigation tools

⚠️ If the Pane Still Doesn’t Appear:

• Try refreshing the browser or clearing the cache
• Ensure your browser window is maximized—some elements may be hidden in narrow views
• If the issue persists, take a full-screen screenshot and escalate to your IT support team

If you’re unable to send emails to specific addresses, the issue may not be caused by your Office 365 account settings, but rather by interoperability between different email service providers.

🧭 Recommended Steps

1. Contact the destination provider
   • Inform them that emails from your address are not being received
   • Ask if there are any blocks, filters, or delivery restrictions in place
2. Contact your source provider (e.g., IIJ)

   • Request a review of outbound mail logs or any delivery errors

📌 Important Notes

• The Office 365 Help Desk supports issues related to Office 365 functionality, but does not troubleshoot delivery issues between external email services.
• Email delivery problems may involve:
  • DNS or SPF record mismatches
  • Blacklisting or spam filtering
  • Server-level blocks or throttling

If you’re unable to sign in to the Office 365 portal, it may be due to incorrect credentials or a mismatch between your Outlook client settings and your Office 365 account configuration.

🧭 Credentials to Use

• Username: Typically formatted as your Employee ID + domain (e.g., 123456@company.co.jp)
• Password: The new password you set when signing in to Windows

🔧 Troubleshooting Steps

1. Check for Caps Lock
   • Ensure Caps Lock is off when entering your password
2. Verify Username Format
   • Confirm you’re using the correct domain and ID combination
3. Try Signing In via a Browser
   • Go to https://portal.office.com and test login directly
4. Contact the System Help Desk
   • If the error persists, your password may need to be reset by your IT administrator

The “People in my organization” sharing option is only available for your default Outlook calendar. Newly created calendars must be shared individually with specific users.

🧭 How to Share a Non-Default Calendar

To allow others to view a secondary calendar, follow these steps:

1. Open your Outlook Calendar
2. Click the gear icon in the upper-right corner
3. Go to Calendar > Shared Calendars
4. Under Shared calendar, select the calendar you want to share
5. Click Share
6. In the Sharing and Permissions screen:

• Users must manually add the shared calendar to their view
• Permissions must be explicitly set for each individual

If you’re using Outlook 2016 for email and Office 365 Calendar for scheduling, and they’re tied to separate accounts, syncing between them is not natively supported. This limitation stems from how Microsoft handles account identities across legacy and cloud services.

📌 Key Points:

• Outlook 2016 uses a locally configured email account (e.g., POP/IMAP or Exchange).
• Office 365 Calendar is cloud-based and tied to a Microsoft 365 identity.
• These accounts operate independently unless they share the same login credentials and are part of the same tenant.

✅ Recommended Workaround:

To ensure your schedules are visible and manageable in one place:

• Manually register your appointments in the Office 365 Calendar interface.
• Use Outlook Web Access (OWA) or the Outlook desktop client signed in with your Office 365 account to manage calendar entries.

Outlook 2016 and Office 365 Calendar may not sync properly if they’re tied to separate accounts. This setup is common when your email account is configured locally in Outlook 2016, while your calendar is managed through a different Office 365 identity.

🧭 Recommended Configuration

• Email (Send/Receive): Use Outlook 2016 desktop client
• Calendar (Scheduling & Events): Use Outlook Calendar via Office 365 Web

📌 Why This Matters

• Outlook 2016 does not automatically bridge calendar data from a different Office 365 account
• Using the web version of Outlook Calendar ensures full access to scheduling features, shared calendars, and real-time updates

The issue was related to calendar sharing permissions in Outlook on the web. It has now been resolved, but to ensure continued visibility of your events to others, it’s important to verify your calendar’s permission settings.

🧭 How to Check Calendar Sharing Permissions

1. Open Outlook on the web
2. Go to your Calendar
3. Click the Settings gear icon > View all Outlook settings
4. Navigate to Calendar > Shared calendars
5. Under “Publish a calendar” or “Share a calendar”, select your calendar
6. Review the list of users and their permission levels (e.g., “Can view all details,” “Can edit”)
7. Adjust permissions as needed to ensure the right people can see your events

📌 Notes

• If others still can’t view your events, confirm they’re accessing the correct calendar
• For group calendars, ensure the calendar is shared with the Microsoft 365 group or individual members
• If you’re unsure who has access, consult your IT administrator or help desk

If events on a shared Outlook Calendar appear only as “Busy”, it’s likely due to the calendar’s sharing permissions being set to “Can view times only”. To allow others to see full event details, the calendar owner must adjust these settings.

🔧 How to Update Sharing Permissions

1. Open the calendar in Outlook
2. Click “Shared” at the top of the calendar view
3. Select the user whose access you want to update
4. In the Sharing and Permissions screen:
   • Change their access level to “Can view all details”
   • Ensure the user is listed under “Within My Organization” or added individually

📌 Notes:

• Only the calendar owner can modify these permissions
• This change allows others to see event titles, locations, and descriptions, not just time blocks
• If the calendar is newly created, it may require manual sharing setup

When accessing Microsoft Teams or Outlook Calendar via a browser, you may notice that the sign-in screen is skipped. This is due to your browser’s credential caching feature, which remembers your previous login session and simplifies future access.

🧭 Key Points

• This behavior is normal and does not indicate a security issue
• There is no difference between internal and external sign-in processes—both follow the same authentication flow
• If you’re signed in with your own account, you can use the services confidently

🔍 How to Confirm You’re Signed In with the Correct Account

1. Open Outlook Calendar or Microsoft Teams
2. Click your profile icon (usually a human figure or initials) in the upper-right corner
3. Verify that the displayed account matches your employee ID or email address

⚠️ Important Reminder

If you’re using a shared device or browser, always confirm that you’re signed in with your own account to avoid accessing someone else’s calendar or Teams environment.

If your Office 365 email works in the built-in Mail app on iPhone or iPad but encounters issues in the Outlook mobile app, the problem may stem from app-specific compatibility, account configuration, or device-level settings.

🧭 Key Points:

• The Mail app uses native iOS protocols (like Exchange ActiveSync), which may handle certain configurations more smoothly.
• The Outlook mobile app relies on Microsoft’s cloud-based authentication and may require additional permissions or updated credentials.
• If your email account is provided by IIJ (Internet Initiative Japan), it may have unique configurations that behave differently across apps.

🔧 Suggested Troubleshooting Steps:

1. Reinstall the Outlook App
   • Delete and reinstall the app to ensure a clean configuration.
2. Try the Built-in Mail App
   • If the Mail app works without issue, you may continue using it as a stable alternative.
3. Confirm Account Type and Settings
   • Check whether your account is set up as Exchange, IMAP, or POP—this affects compatibility.
4. Escalate if Needed
   • If the issue persists only in Outlook, your IT team may need to escalate to Microsoft for deeper investigation.

This issue may be caused by a temporary problem with your network environment or device. If Outlook crashes or displays a loading icon when sending an email, try the following troubleshooting steps:

🛠 Step-by-Step Troubleshooting

1. Restart your device
   • A simple reboot can resolve temporary glitches.
2. Start Outlook in Safe Mode
   • Close Outlook completely.
   • Click the Windows icon and type: Outlook.exe /safe
   • Press Enter and confirm your profile name.
   • If Outlook works fine in Safe Mode, close it and try restarting normally.

If the issue persists after these steps, further investigation may be needed into your Outlook profile, add-ins, or network stability.

This behavior is expected and stems from how Microsoft Teams displays timestamps for email items.

🕒 Explanation:

• The “Sent on” time shown in Teams is based on Coordinated Universal Time (UTC).
• Japan Standard Time (JST), which includes Osaka, Sapporo, and Tokyo, is UTC+9:00.
• As a result, emails viewed in Teams will appear 9 hours later than their actual local send time.

⚠️ Current Limitation:

• There is no built-in option to adjust or localize the displayed time zone for email items within Teams.
• This is part of the platform’s current operational design.

We understand this may cause confusion and appreciate your understanding. For accurate time references, consider checking the email directly in Outlook, which reflects your local time zone settings.

In the current version of Microsoft Teams, meeting organizers do not receive an invitation email for meetings they create. This is a known functional limitation.

📌 Additional Details:

• The organizer is automatically assigned to the meeting and cannot be added again in the “Add attendee” field—neither as required nor optional.
• This behavior is by design and applies across both Teams and Outlook scheduling interfaces.

We understand this may be inconvenient and appreciate your understanding. For record-keeping or confirmation, organizers can manually add the meeting to their calendar or rely on the Teams calendar view.

Following a Microsoft Outlook security update released on July 11, 2023, links to FQDNs (fully qualified domain names) or IP addresses may no longer open directly from Outlook. This is due to a change in Outlook’s internal behavior designed to mitigate vulnerability risks.

🔧 Workaround: Register the Link Destination as a Trusted Site

To restore hyperlink functionality, you can manually add the destination URL to your Trusted Sites list in Windows:

1. Right-click the Start button and select Run
2. Type inetcpl.cpl and click OK
3. In the Internet Properties window, go to the Security tab
4. Select Trusted Sites and click the Sites button
5. Uncheck “Require server verification (https:) for all sites in this zone”
6. Enter the URL of the site you’re trying to access and click Add

📚 Reference:

• Microsoft Support Article: Outlook blocks FQDN and IP address hyperlinks

Microsoft has acknowledged a current issue where the Outlook Calendar interface displays in English, even if another language is set. They are actively working on a fix, but there is no confirmed resolution timeline yet.

🧪 Temporary Workaround

If the issue persists, it may be related to your browser. Try the following:

Clear Microsoft Edge Cache:

1. Launch Microsoft Edge
2. Click the three dots (⋯) in the top-right corner
3. Go to History > ⋯ > Clear browsing data
4. Select Cached images and files, then click Clear now

This may help restore your language settings temporarily while Microsoft resolves the issue.

When adding multiple members to Outlook Calendar, you may experience slow performance due to how the system loads calendar data for each user. This behavior is expected and not caused by a system-wide issue.

🧭 Key Points

• No known incidents have been reported in Microsoft 365 or Outlook Calendar health
• The slowdown is likely due to the real-time loading of calendar data for each added member
• Factors such as network conditions, device performance, and browser behavior may also contribute
• This is a common limitation in cloud-based services where multiple variables affect responsiveness

📌 Recommendations

• Add members gradually to reduce system load
• Use the web version of Outlook Calendar for potentially smoother performance
• Ensure your network connection is stable and your browser is optimized (e.g., clear cache, close unused tabs)
• If performance remains poor, consider scheduling via shared calendar links or using smaller group views

The email failed to send because the message request to the recipient’s email server was unsuccessful. This may be due to a server-side restriction, configuration issue, or temporary outage on the recipient’s end.

🧭 Recommended Actions:

• Contact the recipient using an alternative method (e.g., phone, chat, or another email address).
• Ask the recipient to check with their system administrator, who may need to adjust server settings or investigate the cause of the rejection.
• Verify the recipient’s email address for typos or outdated domains.

We hope this guidance supports your operations and helps you resolve the issue efficiently.

• As a result, emails viewed in Teams will appear 9 hours later than their actual local send time.

⚠️ Current Limitation:

• There is no built-in option to adjust or localize the displayed time zone for email items within Teams.
• This is part of the platform’s current operational design.

We understand this may cause confusion and appreciate your understanding. For accurate time references, consider checking the email directly in Outlook, which reflects your local time zone settings.

In the current version of Microsoft Teams, meeting organizers do not receive an invitation email for meetings they create. This is a known functional limitation.

📌 Additional Details:

• The organizer is automatically assigned to the meeting and cannot be added again in the “Add attendee” field—neither as required nor optional.
• This behavior is by design and applies across both Teams and Outlook scheduling interfaces.

We understand this may be inconvenient and appreciate your understanding. For record-keeping or confirmation, organizers can manually add the meeting to their calendar or rely on the Teams calendar view.
