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.
