I’m pleased to report Blackberry Enterprise Server (BES) 5.0.2 is now supported with Exchange 2010 SP1.
I’ve been checking this page frequently and noticed just this week BES updated the checkbox below:
Notice the (9) after the check mark. If you scroll down you’ll see the footnote:
That KB is called:
Cannot add users to the BlackBerry Enterprise Server 5.0 in an environment that includes Microsoft Exchange 2010 SP1
You can read more about it here:
Essentially it states you’ll run into problems if you choose to deploy Exchange 2010 without public folders (click the link for the fix). While this could have been true with versions prior to SP1 the (9) only shows in the SP1 column. Not sure why.

Great post to share. Planning this weekend to upgrade BlackBerry 5.0.1 to sp2 & sp2 MR1. Called for BB Support for pre-planning issues of our split installation.
I mentioned being disapointed about not having Exchange 2010 SP1 supported yet and they gave me the same good news, with a link to the pdf.
Found your site in my search for kb24470. Appreciate the link. They also mentioned this BB KB23949: dealing with the throttling policy so calendar items don’t come up missing. http://www.blackberry.com/btsc/microsites/search.do?cmd=displayKC&docType=kc&externalId=KB23949&sliceId=1&docTypeID=DT_SUPPORTISSUE_1_1&dialogID=848491243&stateId=0%200%20848487635

Thanks for your comments. I hope you have better luck with RIM support than I did when I installed 2010 about 6 months ago for a large customer. I think there was a new version of the manual with different settings each time I called!
