Active Synch Reboot

[atipa4]

I connect to our exchange server via active synch using Versa Mail. It worked fine for months but recently I've started to have two types of errors:

1. An intermittent communications error which indicates that all data will be wiped from my email and calendar and replaced with new data from teh exchange server(Interestingly, this does not appear to occur).

2. Periodic reboots when automatically synching throughout the day (however, synchs still apparently occur because email is up to date).

Verizon came to the conclusion that the issue was hardware related so we replaced the unit under warranty but the same problem exists with the new unit.

Any ideas?
