@vazaha Hello, usually languages are translated here but not working now. But I understand you're having issues with the Teams add-in for Outlook. What subscription do you use? (business/enterprise) or is this a personal subscription with Teams free? If the latter is the case the add-in won't work I'm afraid.
But if you're using an eligible subscription which includes an EXO license/mailbox you can follow the troubleshooting steps as described here (Other considerations and Troubleshooting).
Use the Microsoft Teams Meeting add-in in Outlook - Microsoft Teams | Microsoft Docs
As you'll see there are quite many considerations. From my experience though, if things should work, these easy steps normally fix it.
- Restart the Teams desktop client.
- Sign out and then sign back in to the Teams desktop client.
- Restart the Outlook desktop client. (Make sure Outlook isn't running in admin mode.)
