I kind of remember having this issue way back in the day, we put a static entry in the hosts file on the BES (we were on 4.1) for the Exchange server and it seemed to clear up the problem, YMMV.

I did find a Blackberry KB article that pretty much just said "if this happens restart the BES", and has not other useful info in it. From: Martin Blackstone [mailto:mblackst...@gmail.com] Sent: 26 April 2011 18:26 To: MS-Exchange Admin Issues Subject: RE: BES - "Lookup Failed"? What is your Exchange version? From: Paul Hutchings [mailto:paul.hutchi...@mira.co.uk] Sent: Tuesday, April 26, 2011 10:14 AM To: MS-Exchange Admin Issues Subject: BES - "Lookup Failed"? Appreciate this is the Exchange list but I also expect many of you use BES so maybe someone's encountered this. We have a dedicated BES Express VM and around a dozen Blackberry's right now. What seems to happen randomly is that sending mail on some/all of the Blackberry's fails, as does the ability to do address book lookups - you just get "lookup failed" on the Blackberry, and restarting the BES fixes it. The BES Express server is running 2003 R2 x64 and the BES Express is 5.0.2.29. Any suggestions would be great.
