I recently had to rebuild a client's network. The domain controller crashed and it was tme for a new mail server anyway. There are only 7 users and only @ a 10 gb Information store there so i figureed it would be easiest to backup the data and backup the mailboxes to PST files (was Exchange 2003 and Outlook 2007).
I ended up with 2008 Server R2 on both the file server and Exchange server and Exchange 2010. All went fine but now i cannot successfullly import the data from the PST files. When i did the orignaly backups to the PSTs there were no errors. After i did the export to PSTs i then disjoined the PCs from the old domain. Once the new network was up i joined them to the new domain. whihc went fine but whenever i try to import the PST file into Outlook 2007 it shows me an error saying that All items could not be imported, some items may have been moved or deleted.
I ran scanpst.exe on a couple of the pst files and it reports that there are way more items and folders in the PST file than what is ending up in the mailbox after the import so i know the PST was done correcty.
