Download internet expolrer for mac. I am having issues with my work's microsoft outlook email account. When new messages arrive into my inbox, they are automatically changing from 'Read' from the 'Un-Read' status, without me opening them or even clicking on them.

I've been using Outlook for Mac with my Exchange account for about three months and it has worked great. Up until about a week ago (may have downloaded an update, can't remember), when I read a message in Outlook, it would mark the message as read on the server (thus my webmail, iPhone, etc.). Somehow this changed so everything stays unread except in Outlook. Not a huge deal, but it's confusing when I have read through most of my email and then it says 45 unread on my phone.
Is there a setting that controls this? Google duo for macbook air free download.
