Issue Status: RESOLVED

Issue Description: 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 is not going to persist across user sessions/team owners.

Final Update: 17/01/2024 09:06:00 AM – Microsoft have confirmed that the fix deployment has successfully completed and remediated all impact.

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

Root cause: A feature update caused the Join by Code feature in the new Microsoft Teams desktop version to not operate as expected.

Next steps: Microsoft are reviewing this feature update to understand why it caused the impact and prevent similar impact from reoccurring in the future.
