BES 5: AD Contacts without Mail addresses

[rainynight65]

Good day,

we are sitting with a somewhat strange problem. I don 't even really know how to begin describing it, so let me just start with the scenario.

We have a BES 5 (Version 5.0.2 MR1) running against a set of Exchange 2010 servers (with SP1) on an Active Directory environment. One of our directors complained that the contacts from his address book that were also on the company directory (i.e. Active Directory) were incomplete on his BlackBerry. Turns out they are all missing their e-mail addresses. We were somewhat flummoxed by this one and ran some tests. Turns out it happens like that for other users as well. It appears that the BES is pulling the info for known contacts out of the Active Directory, but for some odd reason it omits the contact's email address. This does not happen with contacts that are manually created and are not found on the AD.

Personally, I am stumped. Can anyone advise how to solve this issue?
