Title: Users can’t join teams using code generated by the Join by Code feature from the new Microsoft Teams desktop version

User impact: Users can’t join teams using code generated by the Join by Code feature from the new Microsoft Teams desktop version.

More info: This issue only affects those who have a Microsoft 365 Education license. Team owners may be prompted to regenerate Join by Code codes in two scenarios: when users start a new session, i.e. log out and log back in, and when a team has more than one owner and the code generated by one owner is not available to the other owner/owners. In both scenarios, the original code will still function as expected unless a new code is generated. When a new code is generated, any old code will no longer work; however, the new code will work but won’t persist across user sessions/team owners.

Current status: We’ve finished developing the fix and have conducted internal validations to confirm its efficacy in remediating impact. We’re preparing the build for deployment, and we’ll provide a timeline for impact remediation when available.

Scope of impact: Any Microsoft Team desktop user with a Microsoft 365 Education license who’s attempting to copy a Join code for a team which already has a code generated might face this issue, prompting them to regenerate a new code.
