Just a note to people that want Calendar and contacts to sync within their email program (which is what I through everyone wanted within an email program, but apparently it’s not all that common across devices or email clients)…
MAIB (and most stuff using CalDav CardDav Z-push ActiveSync or any derivitive of the term Exchange, Sync, EAS, EWS, etc:
- works in Microsoft Outlook 2016 on a PC (gets glitchy over 1000 messages in one mailbox).
2 DOES NOT work in microsoft OUTLOOK 2016 for Mac - NOR any earlier Version of Outlook for MAC. - you can use El Capitan (iMail, or whatever it’s called) to sync cal, contacts and email.
- the ideal way to use MIAB in outlook on PC (only) is to imap messages and use caldav carddav sync if you can find a good plugin.
Mozilla just announced they are abandoning Thunderbird.
