This has been an ongoing frustration for me for a long time.

I used to be a mutt user – still one of the best email clients out there. That is, if your email comes from an IMAP server and is mostly text-only. No images, HTML, links, etc. Yes, it can sort of kinda work with those things, but please, let’s get real.

Emacs and its various mail modes are of course an interesting option (especially as you can, in fact, display most everything inside modern emacs). And Notmuch is making handling tons of email even easier with decent emacs integration (yes, it’s very early in its development, but for things like reading lkml it is amazing).

Or you can go with Thunderbird (version 3 is really impressive, the tabbed UI takes a little getting used to but then worked rather well for me). Or claws-mail (fast but rather unstable and its single-threadedness really got me to hate it). Or even (yikes) Evolution. Sadly without a strong leader anymore and rather aimless for the last year or so.

But the problem is this – if you want to access work email as well as your personal stuff, chances are that you are forced to integrate with MS Exchange. I can give you tons of reasons why Exchange is a Really Bad Idea™, but of course your corporate IT department is likely to ignore those and tell you “Exchange it is”. And among the biggest flaws of Exchange is its rotten IMAP support. Incredibly slow, barely standard compliant (actually, there are a bunch of annoying bugs). And if you want calendar integration (arguably the best feature in Exchange) there is no good way around MAPI (at least not with Exchange 2007).

And that’s where open source email clients really fail. The only one with even attempted MAPI integration is Evolution. And that is one of the weakest parts of Evolution. Extremely unstable, slow, and so frequently flat out broken that I cannot really suggest using it for day to day work. Emails disappear, or their envelope is there and no content, parts of the headers are missing. The calendar is completely hit or miss: the latest version seems to get my single-instances meetings correct if they come from another user, get the time zone wrong if I enter them myself on the Blackberry or via OWA, and seems to completely miss out recurring meetings that were NOT entered by me. Not useful if I need to be able to rely on my calendar being correct (which is, after all, the point of a calendar).

So… what I do today is offlineimap to get emails from Exchange (or any other IMAP server) into a set of local MailDirs (this hides the latency of the IMAP implementation – especially important with Exchange), then Evolution to read that email locally and OWA for calendar.

Really, not a good solution at all. We need a decent MAPI client. The libraries are all there, the communication with the Exchange server is relatively easy to set up. What’s missing is an acceptable front end that can deal with the typical mess of email that people get (Thunderbird seems to be a good start and appears reasonably active and well maintained), that can do calendaring (again, Thunderbird with Lightening could do the job) and that has a reasonable UI, good keyboard shortcuts for the power users and most importantly is fast. So I guess we need MAPI integration into Thunderbird. Any takers?
