Lost Access to a Team or Channel

Teams Permissions

If you have lost access to a team or channel, please contact one of the team owners to verify your permissions for accessing the team have not changed. If the current owner is no longer available, the team may have expired.

Teams Deletion

The team, channel, or even some of the files may have been accidentally deleted by an owner or member of the team.

• Restore files: Select the Files tab, and click Open in SharePoint. From there, you can access the SharePoint recycle Bin to look for the missing files.
• Restore channels: Click the three dots next to the team name, select manage team, select the Channels tab, and look for the missing channel under the deleted channel list.
• Restore teams: Deleted teams are held for 30 days. Open an Incident as soon as possible to prevent permanent data loss.

Teams Expiration (Group Expiration)

Each team that is created in Microsoft Teams has an underlying Office 365 Group that gets created for managing team membership. Office365 Groups are set to expire every 365 days. At 30 days, 15 days, and 1 day prior to the group expiration, the owner of the team will receive email notifications regarding the pending expiration with an option to renew the team for another 365 days. If a group reaches its expiration and has not been renewed by an owner, the associated team will no longer be accessible to owners or members of the team. The expired group and associated team will still be held for 30 days for an administrator to recover. Open an Incident as soon as possible to prevent permanent data loss.
