Dear Community,
following problem. I'm not able to contact/chat with external Sfb and Teams Users.
I have allowed external communication in the admin center.
We are in "Teams only".
I can not search for external Users in Microsoft Teams.
(i have found a workaround, how external Team can contact me - they call me - it rings on my side - and while it is ringig, the other side starts a chat. Then its working. If they try to contact me without this workaround, a chat is started saying "sfb external" - we are not using sfb anymore - and gets an error that the message could not be sent)
History:
We had an on premise Sfb Server running, which is unactive since 2017.
This week i have deleted all internal DNS entrys mentioning skype, lync etc.
Our external DNS was updated to:
We only want to use Teams. Exchange is still on premise. Also i have waited 24 hours after changing DNS but still no success.
When i try to verify the DNS - it says that everything seems ok:
To mention: I'm not using any microsoft NS? it that a problem?
I have noticed, that our domain is not set to "standard". The onmicrosoft is currently standard. I wanted to do this, but i get following error:
Saying something like: You can not use a external domain as primary. Choose a different domain and try it again. As mentioned - we are using exchange on prem. Would there be any issue when i set our domain to primary?
Side Info:
Product License: Office 365 E3
The users all have as Usernames like "user@ourdomain.at"
e.g. danijel@dicom.at
Also I have noticed, that when i edit a user, the last entry is Skype for Business proberties.
But when i try to follow the link, i receive a blank page

@Christopher Hoard when i check my user it says that the following license is active:
Office 365 E3
When i expand - it gives me a list of all products. Teams and Skype is active (but it says PLAN 2 on Skype - what does that mean?)

Hi @Christopher Hoard
Support Told me in Azure AD to activate
Onetime via Email for Guestuser. They told to wait 24 hours and then it should work. I'm very sceptical.
