Okay, so I have been following all the MAPI info and posts as much as possible, looked like Friday was a good time to dive in. So I did..
MAPI seems to be working pretty well (only 1 user, me). Seems a little laggy, but large mailbox too, but really getting close it seems. Be proud ST! This is cool! A little late ;) But Cool!
Anyway, my specific issue is that I wiped everything, We are on Office 365 E3 but we use SmarterMail for our mail still. So just using Outlook 2019. Anyway, I created all my rules again to move emails to folders, etc. But it is working very inconsistently. I get lots of messages from our windows services and sites (monitoring stuff) and I have rules to drop them in folders under my Inbox. They just don't fire all the time or something. I cannot figure out why, some move and some do not. Strange.
Any thoughts on this would be appreciated.
