Error: The ActiveSyncDevice MY DOMAIN/Ian – Users/Dan/ExchangeActiveSyncDevices/iPhone§78D33F828A7549BF95E4FE cannot be found. Click here for help… http://technet.microsoft.com/en-US/library/ms.exch.err.default(EXCHG.141).aspx?v=14.3.123.3&t=exchgf1&e=ms.exch.err.Ex0FBD0C

Exchange Management Shell command attempted: Remove-ActiveSyncDevice -Identity MY DOMAIN/Ian – Users/Dan/ExchangeActiveSyncDevices/iPhone§78D33F828A7549BF95E4FEFE

The key is the path to the Organizational Unit (OU) in Active Directory.  The user in question is now in:

My Domain/Canada/Calgary/Employees/Dan

but at the time the user added their iPhone they were in:

My Domain/Ian – Users

Soooo, the solution is just to:

1. create the old OU path in Active Directory
2. move the user into that OU
3. go back to the Exchange Management Console and try it again
4. Go for beer
