I'm using a custom made script which imports contacts in AD.
After the import I can see the contacts in Exchange but the e-mailadresses are set as external smtp adresses. Is there a way with powershell or gui to set external smtp adresses to primary smtp adresses? I can do this manually by copying the external smpt adress, choose add and then smtp and choose paste. I receive a notification “the object must be upgrade to the current Exchange version. After the upgrade the object cannot be managed by an earlier version….” Unfortunately I have to this for 3000+ contacts.
I already used this command to upgrade all the contacts to Exchange 2010.
Get-MailContact -resultsize Unlimited | Set-MailContact -CustomAttribute1 Update
But now I still have to find a quick way to set the external smtp as primary.
