"execs that are in there own mail store and they do have large email stores."
Keep in mind that if they have their Blackberry's configured to keep all email the device may run low on memory. This is especially critical on the Pearl, which tends to eat up what little memory it has with the OS. Also, if your execs are like mine they like to "play", and are always loading software on to their phones. If the device is low on memory, the device may start deleting new emails and appointment requests. What looks like an Exchange/BES issue is actually a device issue. The fix is to set an IT policy on BES that will only allow users to keep 6 months or 3 months of email on their phone and will keep users from loading programs...IF your allowed to do that to your execs.

I am have problems with my 4.1.4 and will be doing patching tonight. I have latency, and calendar problems. I have checked cdo and mapi dll files and same version of exchange. Cannot figure it out seems to be only happening to the exec that are in there own mail store and they do have large email stores. Hoping this fixes it cause they are missing appointments. Any advise would be helpful Thank you, David From: Jeff Brown [mailto:2jbr...@gmail.com] Sent: Friday, June 19, 2009 4:34 PM To: MS-Exchange Admin Issues Subject: BES upgrade to 5.0 I saw a post a week or so back but didn't see a lot of response. Am thinking about upgrading my BES server to the new 5.0 version for Exchange. Anyone do this and run into trouble so far? Thanks for any help.
