Problem syncing iOS 13.3 mail with Microsoft online exchange
Everything was working fine until a week or so ago (perhaps last IOS update). New eMails are added to my inbox on my iPhone just fine, but if I read or delete a message on my laptop / webmail / whatever and update exchange, those updates do not appear on my iPhone - every eMail still shows as new and unread until dealt with locally on the iPhone.
