I can’t answer your question, but I was interested in the Exchange categories you mention, as I have tried for years to sync smart mailboxes between computers. I have been able to do this just for one of them, using one of the few available IMAP keywords. Can the Exchange categories help? Are they defined client side or server side? I guess in the second case it won’t help.
At first: Tags are mapped on IMAP keywords. You have to define tuples of Tag/keyword in MailMate settings. In case of Gmail they are triplets of Tag/keyword/label.
Exchange-IMAP does not support IMAP kewords. But you can use DavMail as a local Proxy. It speaks Exchange to the Exchange server and IMAP/SMTP/CalDAV/CardDAV to the clients. The clients have to be configured to speak to 127.0.0.1. This is the raw connection. The authentication and transport encryption is still done between client and server. So there is no security issue. This way Exchange categories are mapped automatically to IMAP keywords.
The "tricky" part is merely to "sync" the used Tags/IMAP keywords/Exchange categories. Unfortunately you have to do it by hand. But if there are only few changes over time it is easy to do.
On every MailMate instance you have to define your tuples. On your Exchange you can edit your Categories for instance via Outlook and maybe OWA. The IMAP keywords will be the Categories. There are no tupels to define on this side.
You just have to make sure that you do your mapping correctly on MailMate.
It may look complicated, but it is not. :) If need more information/help, please feel free to ask.
PS: I have attached my configuration for you (you have to change the server URL). It lets DavMail run in server mode. In this mode, there is no Menu Extra. In the past it did not run stable enough in GUI mode, but in server mode it is rock solid. DavMail is a kick and forget installation. :)
PPS: I have installed DavMail via Nix (a pure functional paket manager) and it starts automatically. Maybe you have to do the autostart by yourself?
