Environment
ZENworks Configuration Management 2017
Situation
Attempting to use Exchange ActiveSync on mobile devices connected through ZCM. The authentication process at the time of enrollment completes but when attempting to get mail loaded onto the device it errors with “Cannot Get Mail. The connection to the server failed”. Connecting the devices directly to Exchange without ZENworks in the middle works properly.
No errors appear logs or communication between the device and ZENworks because the authentication process is succeeding. The only failure is when specifically loading mail.
Resolution
On the Exchange ActiveSync server itself
under the Microsoft Server ActiveSync Properties go to Remote File
Servers – Configure (see attached screenshots).
Under the Internal Domain Suffix List, add
the FQDN of the ZENworks MDM server.
Clients can access only servers that are
recognized as internal. If a server that an client attempts to
access has a DNS suffix that is not on the list, it will be
considered external and will not be accessible to the client.
