Conversations involving multiple participants, allowing collaboration and information sharing in Teams
Same problem, on Mac OS Big Sur 11.1, issue doesnt appear to have been 'caused' by any activity of mine, was working fine last week - booted up today, no updates, no changes, and I get the cannot access content error, works fine on the mobile and so has to be device related.
Thank you to the last few posters on here because, I had changed my status manually, I had quit and force quit the client but I hadnt manually signed out of the client.
Daft as it sounds, logging out the client quits Teams and then on re-initialisation, forces an MFA sync - which lets you back in and loads up your history
Worked a treat and so I'm guessing its a stale auth token in the profile or something given I changed my password 2-3 weeks ago.
