Good afternoon,

A good amount of the users at my company are experiencing an issue where they're checking Outlook and Teams, and then they're prompted to log back into the M365 account. I checked the sign-in logs and there's no rhyme or reason that I initially see.

For some context:

We have a hybrid-joined environment where all devices are registered with our organization and managed via Intune.

  • I have no session timeouts set via Conditional Access.
  • All users are required to have MFA on their accounts, so they're all secure.
  • We use Trend Micro Apex One for our AV solution.

    Hi @ah-pg

    The sign-in error code 65002 occurs when a developer in your tenant attempts to reuse an App ID owned by Microsoft. This situation prevents them from impersonating a Microsoft application to call other APIs.

    There's a similar thread here, and you can refer to the steps provided by @brtrach-MSFT to fix this.

    Sign in error code 65002.
