Hi, we had never used or supported ActiveSync on Mobile - we used CardDAV and CalDAV there anyway ;-)
And for the desktop the ActiveSync feature was very close to unusable for us: unbearably slow, buggy and unstable. Sometimes even whole accounts or sending/receiving mails crashed because of one malformed mail or calendar entry; some accounts need days to sync. The interoperability with the majority of our (Thunderbird or SOGo Web) users was buggy and macOS Outlook never supported it anyway. And even getting it to set up needs a bit of elbow grease digging out the old control panel... CalDAV Synchronizer in theory works better - but needs constant maintanance and is a bit risky as one error could sync every calendar with every other calender in to one big mess... So MPAI could make things actually better for us - at least as long as Outlook Classic is still around as this is also not the current protocoll Microsoft Supports for New Outlook etc., the replacement would be Graph... There is a contestant for the Exchange Protocoll - JMAP - but neiteher are there many supporting clients (though Thunderbird iOS will start with it) nor are there many Servers that do...
