I'm about to work on some Outlook add-ins. It's been years since I did this; and probably several object model revisions!
Can anyone recommend some references to help get me started: blogs, sites, books??
Thanks
If your budget can afford it (ie. the product is making money), I would highly recommend Add-in Express. Lots of samples, documentation, and support -- but requires using their tooling. (It makes Outlook ever so slightly-less of a PITA to deal with.)
However, if you prefer to stick with a (free with VS) Microsoft solution -- it works fairly well, but is missing some "niceties" -- then check out the VSTO on MSDN page as a first stop an follow the links out. There are also some good sample projects, templates, and VSTO tools on codeplex.
Happy coding.
Edit: I guess I must be bored :-) Here are some selected links that I found helpful. some of these are very specific/advanced, and some are more general. The arrangement is in no particular order.
MSDN Outlook 2010 Top-Level. Links to documentation (MAPI, PIAs) etc.
SGriffin's MAPI Internals. Lots of details wrt MAPI. Generally on low-level access but also a good source to find out about changes, new documentation or tools, etc. He could probably rewrite MAPI from memory.
MFCMAPI Program & Source Invaluable tool for inspecting MAPI folders, properties, and whatnot. Is Microsofts "reference example" for most "How do I do x in MAPI?".
OutlookSpy Program. This isn't free, but there is a trial. It may or may not work better than MFCMAPI for particular needs. This was written by the author of Redemption, a supplement/replacement for the PIA OOM access. Dimastr has also answered a number of (advanced) Outlook/MAPI forum posts online -- always a good person to look out for.
Outlook 2010 Messaging API (MAPI) Code Samples - Covers basic (wrapper) implementations of the providers (address/store/transport). All native C++.
OutlookCode.com Site promotes some Outlook books by Sue Mosher. I can't vouch for the books, but the site is a mixed-blessing with some good links, some useful advice, and some downright ugly code :-) Also has a forum.
Visual Studio Tools for Office in VS2010 has come a long way. I used to make (and sell) an Outlook add-in for Tablet PC's and it was very complicated back then. A properly designed add-in in .NET would need to set up a separate AppDomain to avoid stomping on other add-ins and implement all kinds of workarounds to avoid leaving orphaned Outlook processes when the main window closed.
VSTO does all this "out of the box" now.
Don't forget this MSDN forum as a great resource:
Outlook for Developers Forum: http://social.msdn.microsoft.com/Forums/en-US/outlookdev/threads
BTW, @pst: you can still use late-binding to work with the newer Object Models within a version neutral ADX project.
@Josh: VSTO already loads each add-in into it's own AppDomain
@everyone: I work for ADX, feel free to ping me for any questions.
