The file deletion issue is likely due to insufficient storage space on the SharePoint site. When a site reaches its storage limit, certain actions—like deleting files—may become restricted.

To resolve this, you may need to increase the site’s storage capacity. However, please note:

• Storage limits for SharePoint sites (including channel sites) are determined by internal tenant settings.
• Only users with administrator role permissions can adjust these settings via the SharePoint Admin Center.
• The Office 365 Help Desk does not have access to internal tenant configurations or admin permissions.

🛠 What should I do?

Please contact your system help desk or IT administrator to:

• Confirm whether additional storage can be allocated.
• Request access or assistance from someone with SharePoint admin privileges.
• Ensure the site settings allow for file management once space is freed up.
