Invalid External Adress after changing display name RRS feed

  • Question

  • I recently installed Azure Connect and as part of the installation I was prompted to use IDFix to correct AD errors.  A number of our users had blank Display Names.  Adding in the name seemed harmless, but now all of the Exchange mailboxes are giving me an error that the mailbox is corrupted and that the external email address is invalid.  It using the display name I entered in IDFix as the email address.  I cannot find where this is set in any of the property dialogs, they all show the valid email address.  Where can I change or fix this?  

    When I try to login with OWA, I get this....

    Request

  • Figured it out....  There was no "ExternalAddress" object for the mailbox or user when getting them in Exchange shell, but getting the AD User with powershell showed a property called "Target Address".  This was set to the display name by either the "IDFix" program or during the AD Connect installation.  I used a script to clear the property on all users, and now things seem to be OK.
