Deep Link to a Call / Video call does not work with some users

Copper Contributor



we discovered, that a deep link to a call / video call with some users does not work if their userPrincipalName in the AD is not all lower-case (a chat however works fine). It seems there was another thread with the same problem, but it's not available anymore:


Kind regards

Hello @JohannesLichtenberger   Since there has been no response yet from this community, I recommend that you contact Microsoft support or, where support agents are available to help troubleshoot issues until resolution.

Hi Johannes,
we have the same problems.
So I was wondering if you received support already or posted the question elsewhere?
Thanks, Lisa

Same issue here! Not possible to deep link calls to any user with uppercase letters!
