Check the value of the msExchUserAccountControl attribute by using the ADSIEDIT and it should be "0", as in this case it was "2" as shown below:

Usually the value of the msExchUserAccountControl attribute should be updated by the Recipient Update Service (RUS) or by running the Update-Recipient PowerShell cmdlet.
If it can't be updated or populated correctly, then the procedure below should be followed to manually modify the value:
SELECT AdMbxFlags, MbxDisplayName
FROM ExchangeMailboxEntry
