Blackberry 4 wireless sync issue

We are troubleshooting a majot issue. Since upgrading our Firm to Blackberry4.0 server (SP2), and enabling wireless PIM syncing, we are seeing “corruption” of user’s contacts - specifically their FullName field.

Example: User has personal contact named “Evan” in his pnab (in this example, no last name, email address evan@hotmail.com). He makes an edit to that contact on his BB device. When that edit comes back to Notes, somehow the system does a lookup and looks for any other Evans in the FIRM address book. If it finds one, it puts that employees Full Concactonal Name into the full name field (let’s say there is an employee Evan Smith\XYZ Company).

Why is this so bad? Now the person decides to send something to employee Evan Smith. But Notes name resolution sends it to evan@hotmail.com

OUCH!

We are seeing this in 40% of our user’s nabs. It seems to only “infect” situations where there is an unambiguous match. For example, if there were 4 Evan’s at teh company, it doesnt do it.

We are trying to work this with Blackberry, though so far no clues. I am hoping someone out here can give us some advice or seen something similar.

RIM has recreated the problem on their end.

If you use BES4 in your environment, and wirelessly sync NABs that are on a centralizes server, you probably have this issue - which has catastrophic results (emails going to the wrong person).

I am sure RIM can fix easily with a hotfix, though cleaning up the 400 infected we had yesterday took 50+ manhours.
