Hi:

I need to export a BIG mailbox of About  300GB. I contains about 1 month data. I have read about PST max size about 20GB for Outlook 2007-2010 so how can i do this?

What i have tried:

- Using Outlook - it justs freezes
- New-MailboxExportRequest - i just cant find the parameter to export up to some date and delete the messages -OR- a export with a Start date (try to export day-by-day)

Im reading some books and google but no doc on the cmdlet to accomplish this.

Any Idea?

You can do it manually. Open Outlook and Export them folder by folder. PST above 20 GB is not recommended.

You probably could do seperate PST files for each folder.

Below is the filter command

Using filtering when Exporting mailbox content:

Export all content from UserMailbox1's mailbox received between 02/02/05 and 02/05/05 to a folder called User1Data in the UserMailbox2's mailbox:

Export-mailbox -id UserMailbox1 –StartDate "02/02/05" –EndDate "02/05/05" -TargetFolder 'User1Data' -TargetMailbox UserMailbox2

1. Have you read this "New-MailboxExportRequest" article  http://technet.microsoft.com/en-us/library/ff607299.aspx and considered using the IncludeFolders parameter?

2. You could also try using the ContentFilter Parameters in conjunction with other parameters like "IncludeFolders"   Anyway more about the ContentFilter here http://technet.microsoft.com/en-us/library/ff601762.aspx  I think that this would be one way to break it up by date received or sent

2. Unfortunately you cant delete post export process  in Exchange 2010 SP1 any longer, for deletion you would need to sun a search-mail with the -DeleteContent switch http://technet.microsoft.com/en-us/library/dd298173.aspx

3. Outlook 2010 has a limit of 50GB however not so sure I would push out that far (I personally would feel more comfortable using a sub 20GB size) and regardless of the size you choose to stick to I would open and look into each PST before deleting the data since they could be corrupt and if you delete the data without verification you are in a very bad place...

4. Only other option would be to use a 3rd party utility, see my profile for a possible product solution.

There are 3rd party products on the market that can do a PST Split/Overflow, i.e. when the set limit is reached spawn a new PST.  For example on export when Joe.PST reaches 20GB limit span new incrementing PST file i.e. Joe1.pst etc.   Do a Google search for "Exchange Mailbox PST overflow / split"
