MS Teams - unable to search for a user externally
Hello,
I'd like to ask if anyone knows how to fix an issue wherein a person cannot find another user externally in Teams however his colleagues in the same company can exchange messages to the same external user. Both the concerned user and the external user cannot find each other in Teams.
Thank you!
- For me, this was caused by Active Directory having "msRTCSIP-DeploymentLocator" set to "SRV:" for the user.
Clearing this attribute fixed it after it had synchronized to Microsoft 365.
Inspiration was from: https://www.oryszczyn.com/users-in-teams-console-showing-as-uknown/- The above helped me solve my issue :
msRTCSIP-DeploymentLocator was set to SRV , most likely a leftover from a user that was around when we still had Lync / Skype for Business on-premises.
Hi janefriolo ,
Is this when you are adding the external users email address to the big command bar at the top? Does it not come up with "Search for <email address>" externally?

Andrew Hodges It's the icon on the left side we clicked. The box with a pen. The user was getting "We can't set up the conversation because your organizations are not set up to talk to each other." However his colleagues were able to message the external user. It seems to be an isolated issue.
- Most likely one of your users is set to Teams only and the other one Islands. External chat will not activate unless your set to Teams only, otherwise that external chat happens in Skype for Business.
I would start there by seeing if users are set to different upgrade modes in the Teams Admin center.
