I'm trying to add a mailbox to an existing account specifing the Primary SMTP address and then adding the X400 and a secondary SMTP. This is what I have ... enable-mailbox -Identity <UserIdParameter> -Alias <string> -Database <DatabaseIdParameter> -PrimarySmtpAddress <string> #Start-Sleep -s 15 If I put a 15 Second delay here it works. If I don't I get a object email address not found error. I don't want to have the delay. $usermbx = Get-Mailbox UserName $usermbx.emailAddresses+='SSmtpAddress','X400:C=US;A= ;P=CCCI;O=WHQ;S=lastname;G=firstname;' Set-Mailbox $usermbx -emailAddresses $usermbx.emailAddresses Is there a better way to do this, so I don't need the delay?

That tends to happen, I remember someone having the same issue. Though I'm not sure what he did to fix it the likely issue is due to AD replication, it depends on what DC the mailbox server is looking. See if you can specify the enable-mailbox -domaincontroller parameter to target a specific DC and see if it makes a difference.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi Can you choose the nearest AD to be default and try to do the setting again. In fact, I think 15 second delay is not big issue.
