> So you will have a choice of 3 commercial Outlook plug-ins, What are the 3 commercial Outlook plugins? Obviously the Toltec one, but which others? I've actually always liked the idea of what toltec + bynari were doing. It's basically using the IMAP server as a database where folders = tables, emails = records. The nice things about using an IMAP server is that: 1) you're reusing a protocol, rather than creating another one 2) emails can't be altered, so an update is a delete + add which makes detecting changes easy 3) the server is always authoriative, so syncing tends to be easier Of course reusing an email protocol to do these other things it was never meant to do seems hacky as well. Still, is it really any more hacky than using a blatant file protocol (despite calling files "resources" and directories "collections") than CalDAV? As an FYI, last time I tried Bynari and Toltec, my general conclusions were: Bynari - Annoying they use a binary format for storing the information, but good that they use the 0-9 ACLs to designate what folders are calendar/contacts/etc folders, means you don't need the damn ANNOTATEMORE extension and the patches to make it work with arbitrary values. Seemed a bit "flaky". It creates some process that runs next to Outlook, and sometimes that process wouldn't quit when you quit Outlook leaving things in an odd state. Install/removing the software seemed to be prone to failures/screwing up your config. Toltec - Seemed less prone to bugginess than bynari, and using an XML format seemed more open so we could read it ourselves for other features in the future. Using ANNOTATEMORE was a pain. There was a showstopper problem however. When I tested it seemed that Toltec would display all sub-folders of INBOX, and using annotations it would set the Calendar, Contacts, etc folders as appropriate to display those items, and all other folders to display emails, but it would not show the INBOX! At the time I asked support about this it was suggested that you should setup a POP account to download the emails from the inbox to the "Local Folders" PST file. This seemed to completely defeat the purpose of IMAP to me. Has that been fixed? Also out of interest, how much caching does toltec do? Basically it seems to me to get any decent performance you effectively have to download all the calendar/task/etc items from the appropriate folders and cache them all inside outlook. Any attempt to get from the server on a "when needed" basis seems like it would never perform well?
