Exchange 365 read and deleted message sync to emClient

Hi there,

I use emClient on a desktop computer at an office and Outlook on a mobile and laptop. When I read a message in Outlook, it will change status to “read” on the mobile Outlook, laptop and online. On the emClient machine, the emails remain in the inbox unread until you click on them and “read” them. If they were deleted on the mobile or laptop they will change to “read” and then disappear when selected

Any clues how to fix this annoying sync issue?
