I am new to administering MS Teams, but i have searched high an low for a problem I am having with some users not able to access external teams. Myself, and most of the users i have tested can 'search' externally when initiating a chat session, but i have one user that cannot.
I have checked to see if licensing is different, and have gone over the external checklist from the Teams admin to make sure we can access outside our organization. Since I and my other users can access outside the org, I am pretty sure that is set up directly.

I went to check the policies assigned to the users, then noticed that the users that cant access external users are NOT listed in the "users" area of Microsoft Teams Admin Center, but ARE assigned a license..
I have tried to delete license, and reassign through web interface and alternatively through powershell, and still the users have not showed up in the Teams Admin center. I have given ample time for license sync. There is no place in teams admin center to add users, it directs me to the o365 admin center.
@ChrisWebb - i dont know how to turn off/on manual upgrade mode. This is all a new set up, so there has not been any migrations.

@Chris Webb, is this still the case regarding requiring the SfB license be provisioned to chat with an external user? I'm seeing a similar issue with some users not being able to add external (whitelisted) users to a chat, but those that CAN don't have the SfB license assigned either.

@Chris Webb That makes sense, thank you. With some users able to connect with the same external user and others not I think that indicates the external user license provisioning shouldn't be the issue. I'll dig in more on whether our 'broken' users may have cached settings, any other potential sources to check are appreciated though!

@MichaelThomas Good morning from Toronto,
I seem to be having this same issue. i have some users who are able to chat with external users and some who cannot.

I had a user who was able to add an email and the same user tried adding a different email and didnt work.

@ronomatic Our issue ended up being a SIP Address/UPN mismatch wherein a limited subset of users were using a legacy domain in their SIP address (we're a new Teams org and still have a separate voice platform in use). The whitelisted org that we correspond with had not whitelisted our legacy domain, they added our legacy domain and the issue was resolved, but we also updated SIP addresses to match UPNs.
