How do I add a guest mail user to adress lists or create a mail contact using the same email address
To be honest, it's a bit of a mess as you can actually have the same address added twice:
[10:36:59][Login script]# Get-Recipient tempxxx@abv.bg | Ft Name,RecipientType* Name RecipientType RecipientTypeDetails ---- ------------- -------------------- temp MailContact MailContact tempxxx_abv.bg#EXT# MailUser GuestMailUser
The "trick" is to have the contact first, then provision the Guest account. Doesn't really make much sense to me, but TonyRedmond seems to see the logic in all this and perhaps can explain it better :)
LennyK_108 malfaro It is also possible to add 'Guest Mail Users' to Distribution Groups via a web browser without using PowerShell. Go to the Microsoft 365 Admin Portal - find the Guest Mail User under Users/Guest Users, select them, and click 'Manage groups' on the left hand side.
It takes a while for the group list to be updated in that console, but the changes are visible in the Exchange Admin Centre immediately.
