How do I add a guest mail user to adress lists or create a mail contact using the same email address
Hello,
I'm trying to create a mail contact for an external user so we can add the user to an address list. Unfortunately, I can't create the contact because the primary smtp address is taken by...
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 :)
I know this is late but people are still trying to find a solution, so another option is to null the proxyaddresses attribute for the mail user. (Set-MailUser -Identity <Identityofmailuser> -EmailAddresses $Null). This is essentially what happens if you create the contact first anyway. Then you should be able to create your contact.
