Hi Maxvdm ,

I am afraid not or at least I haven't checked in a while, but presume nothing has changed. Only experienced this in a Dev environment, so didn't really look much further.

I would check the basics though and ensure that the external user you are trying to connect with, has the external access ability permitted within their tenant and the same for yourself also.

Thanks

Henry

Hi, I know it's been a few months but if you are still having issues, this is what I have found in our company.
When using Teams to contact external companies, both end user must have their Teams coexistence mode set to "Teams Only", any other configuration causes major issues. This is due to Teams using a Skype back end to transmit messages externally. Hopefully this will change after July when Skype goes end of life.
