Calendar entries older then 7 days being deleted.

I have a number of users that for one reason or another have calendars that seem to only keep 7 days worth of entries. Anything older then 7 days is deleted from their blackberry device.

Has anyone seen this before?

We are running email on Lotus Notes 6.5.6 FP3. The users are running on the R6 Notes Template. My Blackberry Servers are running 4.1.6.17

Thanks,
