Hello Richard,

Do you have any URL redirecting on your environment? This can cause the error mentioned.

If you try to login via OWA to a users mailbox with the impersonation account does it succeed? If it doesn't it is likely the issue is with the permissions applied to the CUC account.

This test was for the UM service account if you run the test for the user does it display a different message? This could help to isolate.

Also make extra sure you applied the permissions to all applicable Exchanges, commonly clients only apply to one of them:

Step 4 If you set permissions on individual Exchange server in Step 2 and you have more than one Exchange 2007 server, repeat Step 1 through Step 3 on the following servers:

•All other Exchange 2007 client access servers that Connection can access.

•All Exchange 2007 mailbox servers that home mailboxes that you want Connection to be able to access.

Hello David,

Thank you for you response! 

It was definitely a permissions issue.  It worked after applying "Get-ExchangeServer -Identity ServerName" to the Exchange CAS servers.

5 STARS for you!
