Hi,

One of our users keep getting an error message when opening teams, this is only happening to a single users, on their machine, unfortunately I am not able to check if it would work on other machine or if other users can work on their machine due to working from home. Basically it opens, asks them to login, when they login it doesn't ask for password it just goes straight to the error, and we can't get further, they are able to login to teams.microsoft.com, but the app wont work, I have tried the following steps:

Reinstalled the app

Rebooted the machine

Uninstalled the app, cleared the cache and then reinstalled the app

Closed the app and cleared the cache and then reopened the app

Removed the teams license from o365 admin portal, then re-added the teams license

is there anything else I can do to try to resolve this issue? 

Kind Regards,

Brendan

    After trying everything else I found a fix that works for me. Rename the Crypto folder in this location to something like Crypto.old

    %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AC\Microsoft

    Teams will generate a new folder on next launch with a new token. I guess Teams for some reason stops liking the cached token?

    Hi there

    what worked for me was going of the LAN/WLAN and using pure internet connection to sign in.

    this worked and now I am fine again.

    thanks

    Hi folks,

    I work in IT and had the same problem, came here for some advice. Actually found that app enforcement managed by the router was preventing Teams from communicating through the WAN, have disabled this and signed in without a hitch. This might have been causing problems with other apps like Outlook as well.

    Hope this helps

    Regards,

    Ben
