Migration to O365

Question

Hi,I have issue creating mailbox in hybrid.We have exchange 2013 with root domain as abc.com.&nbsp;Domain xyz.com is added as primary domain in O365 (cant add abc.com as we don't own it. We are a part of shared service).User creation in AD is Automated.Now whenever we create remote mailbox using Enable-Remotemailbox -identity Alias -Remoteroutingdomain xyz.mail.onmicrosoft.com the remote mailbox is created with emailaddress of rootdomain of exchange and it becomes user@abc.com instead of user@xyz.com.Any way we can change email address to the domain added in O365.The default email address priority is lowest and the email address policy that needs to be applied to the remotemailbox is highest but the default email address policy is applied somehow to remote mailbox.&nbsp;Any suggestion is helpful.

Have you tried using the&nbsp;PrimarySmtpAddress parameter?

Hello Vasil,Thanks for responding!!But the -PrimarySMTPAddress switch would disable emailaddress policy which inturn clears the Remote routing address.

I thought this was the whole idea? You can still adjust the remote routing address with the corresponding switch.

VasilMichev&nbsp;The user creation in AD is automated. So primary SMTP is generated as Alias@domain.com, and Alias is Firstname.Lastname. If Alias exists a random number is added.So to automate user creation we were thinking to just add the enable-remotemailbox command after user creation in AD.Now you mean to say I should use following command:Set-remotemailbox -identity user@domain.com -PrimarySMTP Address user@domain.com -remoteRoutingAddress Alias@domain.mail.onmicrosoft.com
