Why is calendar removing previous month's appointments?

[Counselor]

My outlook calendar sporadically will remove my appointments for a whole
calendar month. Example, While in February, all appointments prior to
December have been deleted. This will happen occasionally. But is
frustrating b/c I can't keep track of my client's past appts. for billing
purposes. I do sync with a blackberry also (two way sync from calendar to
device and vice versa). Can anyone tell me a solution for this problem? Is
there anyway to get that old data back into outlook?

Configure your Blackberry to keep old items forever. This is not an Outlook
problem, it's a Blackberry problem.

Is there anyway to get that old data back into outlook?

Restore it from your most recent backup. Changes made by a sync are
permanent.
