Question Regarding PST Importing
Posted on 2010-04-02
With this question, I'm looking for some sound advice and steps on the best way to handle this. We've recently begun a migration of all of our in-house Exchange mailboxes to a Microsoft Hosted solution in the cloud. Moving the mailboxes has been pretty smooth so far but we had a problem with one mailbox
After the migiration, we noticed that in a good amount of her mailbox's sub-folders, that a large amount of the emails appeared damaged (wouldn't show the entire message but only a few lines). Looking at her old non-migrated mailbox, all of the messages were intact. We exported several thousand messages from the old mailbox into a PST so we could import them into the new mailbox.
My question comes during this process. When I import the PST, I have several options; Do not import duplicates and Import and overwrite. I guess I'm a bit confused here. If the messages in the PST and the migrated mailbox are the same and I choose "Do not import duplicates" will anything from the PST import in? If I choose to important and overwrite, will the import actually overwrite what's in the mailbox or will it make a second copy of each email doubling the amount that's already there
If you all have further questions or need more info, please let me know so I can try to elaborate further. Thanks!
