I am sorry that you are experiencing these issues with the webmail service lately. It seems like a strange issue that is happening. I was wondering if you could help me better understand the issue, are you using a different browser recently, or have you recently changed any of the settings within your webmail? I understand that the webmail is working properly but just that when you click on an email itself it takes longer to open the email, and then it is marking the email as read before it opens?
The first thing we would want to try is clearing the cache by pressing Control and F5 at the same time while the browser is open, and completely restarting your browser (closing it down completely, quitting out if needed and restarting it) then re-opening the webmail site, and checking to see if the issue is still persisting. The second thing we would want to try is opening webmail and signing in on a Different browswer (firefox, safari, internet explorer, opera) and seeing if the issues are still happening on that browser.
Thank you for reaching out with this strange issue, and I hope together we can get to the bottom of it!
