I’m probably the 100 millionth Microsoft Outlook user who ran into the dreaded winmail.dat-issue while switching from POP3 to IMAP. I posted to the microsoft.public.outlook newsgroup for help, but got none.
In the meantime I found a rather straight forward solution to move all my Outlook email from a .pst/.ost file to the IMAP server. You just have to leave the Microsoft world:
- Install Mozilla Thunderbird
- Tell it to import the email from your current Outlook installation
- Create a new IMAP account in Thunderbird
- Move all the imported email to the IMAP server with Thunderbird
- I case you still want to switch back to Outlook – chances are that you won’t, since Outlook is a real bitch when it comes to IMAP support:
- Uninstall Thunderbird
- Create a new IMAP account in Outlook
- Delete your old POP3 account

works great – perhaps not a “one click solution” but with a little bit of folder drag and drop it is a real good idea…
thunderbird createda all my outlook folders in the local area – then i sent them to my imap account.
once again – thank you from oliver/berlin
