Internal Teams user showing as External
We are experiencing strange behavior in Teams, sometimes few internal users are showing as external user. This is mostly happening in Teams Mobile app. Any idea pls?
Jaisson Hi i followed your process i did remove files and folder from %appdata%\Microsoft\Teams
and it worked for the use.
Now after a month user is contacing me with the same issue.
So it work as workaround but i need a better solution.Thanks
So let me share my solution to this problem. I had this same error with one of my internal organization contact showing as external. Digging deep I found we had a contact created for that user pointing to his external private email (also Teams enabled).
External contact email attribute was: username@CompanyNA.mail.onmicrosoft.com
Checking AD attribute for that internal user showed attribute: targetAddress: username@CompanyNA.mail.onmicrosoft.com (basicly pointing to that contact address)
Changing targetAddress attribute to: username@CompanyNA.onmicrosoft.com resolved our issue.
Somehow our internal user get linked with that contact address.
Hope that helps someone.
Berglez Hello, I Had a similar issue in sharing and permissions for a shared calendar and I was pretty sure it may have something to do with your issue. Let me know if they relate!
Anyway, the resolution ended up being the licensed user was a shared mailbox (though was still signed into the account via Outlook as a regular account).
After switching the shared mailbox back to a user mailbox, the issue was resolved. Hopefully this happens to be your case!
