Calendar disappear

I have 5 of these Black Berry Torch 9800 to 9810. Starting a month ago, my users experience Calendar items disappering and re-appearing. I can re-activate the phone with the BES server. I can see all Calender Items there in the phone. However, for some reason most of them disappear in hours. Sometime, one or two item re-appear again.

I have Exchange 2010 sp2 ru 4 with 2 cas and 2 mailbox servers.

Can any one give me a lead of how to solve this?

Re: Calendar disappear

Could be the blackberry is extremely low on memory and starts deleting messages to make space.



Please check the link/s and see if the solution helps.

Re: Calendar disappear

Thanks for the information.

I did follow that article to Set-ThrottlingPolicy BESPolicy  but it still did not work.

The strange thing is the calendar sometimes reappear for a while and disappear again. I can re-sync the phone and get all the calendar populate again but they disappear after awhile. I checked the permissionm BESAdmin has full mailbox permission.
