Occasional Visitor

Hello,

I don't know how to behave in this scenario.

 

There is an Office 365 organization for the domainA.com. Users are synced with AAD Connect and Hybrid Configuration is in place with Exchange. In this Exchange on-prems organization there is a synced user in AAD corresponding to a mail user whose external email address of the mail is John.Doe@domainB.com

John.Doe@domainB.com is a member of the domainB.com Office 365 tenant and he must be add to a Microsoft teams team as guest user, so he may log on with Office 365 credential.

If I try to add his as guest user I get an error, but I can add it as member of the team using the synced user, but, if I do so, I must assign a Microsoft Team license.

 

Any suggestions? Thank you

 

Enrico

@EnricoGiacomin Hi, you can workaround it creating a John.Doe@domainA.com account just for add it as a member
