I had an Exchange 2000 server that crashed, I recovered the PST mailboxes from the .edb database.

Now I'll move to a linux webhosting with imap support. I've to import the PST contents in the respective new mailboxes on the new server.

I've already tried several ways:

1- OUTLOOK IMPORT: Importing using import/export wizard fails because it complains about destination folder containing different "type of objects" (Note: translation from italian message) than the source one

2- OUTLOOK MOVING FOLDERS: tried to attach PST to outlook and move folders of mailbox in the IMAP mailbox also connected to outlook... but same way: impossible to move folders: I have to create every single folder and move the mails into (but is a big PITA for 16 Gb of mailboxes)

3- Using Linux converted PST to MBOX using "readpst" on ubuntu, then tried to import using ImportExportTools from Thunderbird extensions, but again no luck, I can just put this in local storage but not import these folders directly in IMAP account.

anybody can help me?

readpst can convert PST files to mbox format


If you are able to successfully convert your PST files into MBOX format, then there are a variety of tools you can use to import those messages into an IMAP server, including:

Both may already be packaged for your distribution.

  • Tried this but readpst splits every PST mail subfolder in a different mbox file, so I'll have to restore manually (or script something) the folder structure on the imap server.. a bit too long. thanks by the way. I'll use imapsync to sync the mails from the temporary server to the definitive one.

You can try Mailstore. It's possible to archive and export mailboxes of variant sources. The 30 Day trial is a full version. I'd use it for moving E-Mails from a Linux Mail Server to Microsoft Exchange.

Archiving of Emails From Different Sources

  • Microsoft Exchange Server 2003, 2007, and 2010 (incl. SBS)
  • Hosted Exchange
  • Microsoft Office 365
  • MDaemon Messaging Server
  • IceWarp Mail Server
  • Kerio Connect
  • Any IMAP- or POP3-compatible email server or mailbox
  • Email clients such as Microsoft Outlook and Mozilla Thunderbird
  • PST and other email file formats
  • This software is the best-fitting solution to my problem. thanks a lot.Anyway I had to use readpst to convert quickly all the Contacts in vCard format to import in Thunderbird clients.

  • I have to say there's a problem with this software in doing it right... many subjects and dates are invalid once imported into IMAP folders... I'm trying other ways
