Hi,
I have been doing a mailbox export for a user with quite a large mailbox (17GB) and the PST files created are extremely big. I first tried doing a single export but the pst file created was over 50GB so the export would fail. I found out that the export could be done by date range so I have been doing that over the last week or so. The powershell code I have been using for each is:
New-MailboxexportRequest -ContentFilter {(Sent -le '12/31/2011') -and (Sent -ge '01/01/2011')} -Mailbox "Michael" -Name Michael_Sent_2011 -FilePath\\ServerName\MailArchive\Michael_Sent_2011.pst
The only thing I have changed are the date ranges, the name of the pst file and whether I'm exporting Sent or Received emails during that time.
So, the problem is that although the mailbox is only 17GB the pst files are around 8GB each (so far I have done Sent items for 2010, 2011, and 2012 as well as Received Items for 2010 and 2011). One of the files was ever bigger at over 12GB (and still going). So for the 5 exports I have done so far I'm up to 42GB worth of pst files. I can only assume I am doing something wrong. Is there something wrong with the Powershell code or should I expect the pst files to be this big?
Any help would be greatly appreciated.
Thanks
