evpm import empties/clears mail from PST
New to using EV here, and I'm hoping this is a straight forward q and a.
Running EV 10 and importing PST via EVPM command. After importing the data to EV we've noticed that the PST files are either partially empty, or mostly empty. So partially empty means that we've noticed a PST with folder that had about 20 message only have 10 after import. And mostly empty means we've noticed PST file that only has a small amount of calendar data, were as before it had say 1000's of messages and the PST file was say 2GB in size.
So my questions
1. Does the import process delete the mail data as it imports into EV?
2. If so is there a way to turn off (deleting mail from PST during import) or is this by design?
3. If I see mail/calendar items in PST after import does this suggest that it wasnt imported into EV due to a policy restriction or something logical like that?
