Exchange 2007 move .pst files to another Host

baleman2 used Ask the Experts™
Our Exchange server has been temporarily hosting 75 users.  This small company has found a permanent hosting company for all their needs.  I now need to export all pertinent Exchange information to the new hosting company.

Is this as simple as zipping up individual .pst files and emailing (ftp, dvd, whatever) to the new hosting company?

Anything special for the new hosting company to do?

Yes it should be that easy.

We have migrated a few customers over to Hosted Exchange.  Our provider have us RDP access to an 'import Server'. We then import the PST files into Exchange (Sent to them on an encrypted hard drive.)

Speak to your provider as they may have a set procedure for it.
First check what the other company is using as its exchange server, is it MS exchange or IBM lotus, if exchange than you simply make sure that all .PST files are up to date and ask the company to create all the email ids and then map those to existing .pst file when you get them

In case of Lotus Domino then you need to consider migration from .pst to .nsf
Yes, you should be able to zip the PST's and send them to the hosting company. Depending on their size, you might need to split some of them up so they can be FTP's or sent by email.

The hosting company should be able to import them into the appropriate email account.

Hope this helps!

When I google (exchange 2007 export .pst) I'm receiving a lot of information stating that this "export" must occur from a 32 bit machine - see attachment.

We're running Exchange 2007 on Windows Server 2008 Standard - 64 bit.

Please advise.
It shouldn't matter if your using 32 or 64. To be carefull, each user can run a COPY of their email into a PST file so the original mail remains in the mail store just incase there is a problem on the remote side.

I would try it on a few mailboxes. if you don't have a problem, then proceed with regular exports and have them moved in on the remote side.
Have you tried any of the PST exports?


Apologies to all.  I'm in the middle of a different migration project on several servers and have not been able to give my attention to this issue.  

To TG-TIS:  I've not attempted any of the PST exports yet.  I was hoping to be able to use some sort of GUI interface from within Exchange to perform this task; but, unless I'm overlooking something (haven't found a solution), it seems I must do this from the command applet - correct?
I work with 2003 & 2007 and have not seen a GUI in Exchnage to perform that task. There probably is a 3rd party app like something from Quest, but I have not needed it.

Here are a few I found


From my comment above, note that we're running Exchange 2007 on a 64 bit Windows Server 2008 machine.  We have no 32 bit servers in our datacenter.  Below is an excerpt from an article telling me I can't do this otherwise.

Please advise

"What came as a big surprise was that you can’t just log on to an Exchange 2007 64-bit server and then export the mailbox data to a PST file using the Export-Mailbox command. Actually it’s not possible to export data to a PST file from a 64-based Exchange 2007 server; you must instead run this cmdlet on a server or client with the 32-bit version of the Exchange 2007 System Management tools installed. In addition, you must install Outlook 2003 SP2 or later. Yes I’m not kidding here, and the reason why this is so is because Exchange 2007 doesn’t contain the Outlook PST provider like previous versions of Exchange Server did."
