(Or – unlikely – if you only started using Thunderbird very recently and did tick the box to use Maildir format for storing mails, I’d expect you could then hunt down those directly on the disk, rename or copy to add the.

Exchange server “Outlook Web Access” does support UTF-8 CSV import, but if you have that you probably could just do server-side sync…įor mail conversion without server-side support, the linked approach should work, or you can use the Thunderbird ImportExportTools add-on to produce “EML” format output.

Still technically possible to keep using both Thunderbird and Outlook simultaneously.Īddress book export to CSV and Outlook import from CSV is quite possible, but last time I checked there was one potential problem – Outlook doesn’t support UTF-8 mode CSV import or export, and if your contacts have non-ASCII characters in names or whatever (as in pretty much anything outside base English) in Thunderbird they’re probably in UTF-8. If you’re moving to a somewhat locked down server with EWS still enabled, you can still go that way but it’s no longer as easy – need to install and configure DavMail (and Java if you don’t have that already) as a protocol translator. (TbSync, Exchange ActiveSync for TbSync, possibly also CategoryManager depending.) Also enables continuous concurrent access though with some sync delay on contacts changes. Server-side sync by ActiveSync is the easiest way for contacts, but then you’ll need an add-on or two for Thunderbird. If your personal folders are all on an IMAP-capable server, or you’re moving to one (such as MS Exchange or Office 365) you can even keep using the folders from both Thunderbird and Outlook simultaneously, no additional software needed. There’s a free and fairly easy way to do all this if you have an account on a Microsoft Exchange or equivalent server with default permissive settings (IMAP and ActiveSync allowed) and can install per-user add-ons in local Thunderbird.

This would obivously depend on what you’re using for the storage and where the need comes from.
