Conversations involving multiple participants, allowing collaboration and information sharing in Teams
Dear LukeTW,
Good day! Thank you for reaching out.
I understand that you are having an issue with your teams not loading older messages. May I please know whether you are running teams on android or iOS?
Have you already tried try to clear the cache and data of the Teams app and check whether there's a difference. To do this, for Android, go to Settings > Apps > Teams > Storage > Clear cache and Clear data. Then restart the device and Teams.
->For iOS, go to settings >Teams >Enable clear app data >Quit and restart teams
In the meantime, please confirm with your teams admin whether they have set up a retention policy to delete teams messages after a certain period for your account. Example in this document. Manage retention policies for Microsoft Teams - Microsoft Teams | Microsoft Learn
Looking forward to your response.
Best Regards,
Ashraf.
