SUMMARY
When I mark messages as "Read" in KMail, they may or may not be marked as read on the EWS server hosting my mail. I do not know what causes some to be marked correctly and other to not. Even restarting my machine will still show those messages as "Read" locally, even though they are still "Unread" on the server.

STEPS TO REPRODUCE
1. Mark messages as read

OBSERVED RESULT
Sometimes the messages are marked as read on the EWS server, sometimes not

EXPECTED RESULT
I would expect the "Read/Unread" status to be properly reflected on the server, or if it failed, then the local status should reflect the status on the server.
