I’m trying to access Teams to schedule a meeting but keep getting this error message:

Please help (I’m not an IT specialist, this is for my charity work and is happening on the Teams (and Authenticator) App on my mobile (iPhone). Thanks.

If all clients cannot log in, contact your Microsoft 365 administrator to run Teams sign-in diagnostics for the user.
You can also run the Microsoft Remote Connectivity Analyzer diagnostics to help you troubleshoot the issue.
If the issue only occurs on mobile, try uninstalling Teams and reinstalling it, and report the issue in the Microsoft 365 admin center.
