BlackBerry Server MAPI Connectivity Issue


When trying to resolve the Exchange server profile on BlackBerry server following error appears

“The name could not be resolved. Network Problems are preventing connection to the Microsoft Exchange Server computer. Contact your system administrator if this condition persists.”


This could be caused due to many reasons, but one that I would check the last (not even that) caused it on our BlackBerry server.  When BlackBerry server is installed and for the first time MAPI connectivity is established through Exchange Collaboration Data Object, it uses a Global Catalog server to authenticate. If GC role is seized from that server, above issue occurs.

To fix it I had to enable the GC role again on the same server and it started to work fine. I tried a few registry tweaks to get the BlackBerry server to find nearest GC with no success. Will try to find a better fix, meanwhile if you have any suggestions please comment.
