Read mail continues to show as Unread

I only had this problem with Facebook email notifications when i had Yosemite. When i updated to Sierra (skipping El Capitan) in April, i now have this problem and many many other email problems i wasn't having before, lots of beach balls, mailboxes displaying no mail in them or only a few mails, taking a very long time to load, all rules suddenly inexplicably deleted except News From Apple, which was the only one i didn't create, and one of the worst things, inability to quit mail. It starts the quitting process and then just hangs there, and it's usually because i want to restart the computer but it can't restart because Mail is not able to quit, and i can't make it force quit, the most recent time, it was neither quit nor not quit, the little dot showing that an app is open, under the icon in the dock was gone, but Mail continued to show up in the window with Command Option Escape, and would not respond to force quit command. Clicking on the mail icon in the dock had no effect. even hard restarting the computer didn't make the program functional again the first time. 😟

I have been having the same problem with read mail for sometime. Up until the most recent ios11.1 I was usually able to clear it as read by continueing to delete it. But after upgrading to ios11.1 I not only cannot get the mail to shiw as read, I cannot delete them or flag them. They always returnntonshow as unread.

Hi RAmeeti0,

Thank you for being a member of the Apple Support Communities! We’re glad that you took the time to post this question!

There could be a couple of different reasons you have an read email showing as unread. If this email is part of a thread, a series of multiple emails going back and forth, make sure that you have looked at each email in the thread so that it will acknowledge as being read.

Another helpful step you may try if an email remains marked as a new message with the blue dot is to select a different message from your inbox and then select the message showing as unread again.

Another resource you can use to mark your mail as read is located in the following article.

I am having this same problem

some messages still have the blue dot indicating they are "new" even if they are not.

i try to swipe right (new move in El Cap) to "mark" and it thinks it is already read (ie- I have the option to "mark as unread"). I do this, and then try again to "mark as read" and still no improvement

if I close MacMail and re-open, it updates, appropriately and they are no longer blue-dotted.

Same problem here. Since El Capito update, most mails (from Exchange server) do not visually mark as read. No obvious pattern, it seems to occur randomly. Closing and re-opening Mail visually updates and marks as read. Please fix.

I am experiencing the same. None of my mails (from an Exchange 2010 server) are marked as read when I read them on my iMac. When I read the mail on my iphone they are marked as read even in mail on my iMac. The mails that a read on my iMac are marked as read as soon as I restart mail.

I've been using Apple's Mail program for decades. I read my email almost exclusively on a MacBookPro. Two days ago, I upgraded to El Capitan. Since then, I've been having two problems with mail. (1) The first is the one under discussion: random incidents where mail that has been read pops right back to having a blue dot, as though I had not read the mail. These emails are not part of a thread. (Note: If people accidentally hit the archive button, because they are used to the far left button being the delete button, the message will not be deleted.) (2) The second is that I cannot erase a message if it is open. When I go back to the email list, the message is still in the inbox (and marked as unread). After I've read such a message, I can only trash that message if I do so directly from the inbox list. I believe this problem is also random, but I'm not certain it is not consistent; I will take not of consistency or non-consistency as today goes on.

Could this issue be related to the Cloud?

Come on Apple, this is an unexcusable issue. I have the same problem with read emails being marked as unread. I also have the added trouble of loosing connection with one of my most important email accounts. I've read all the blogs about El Capitan email issues, I've tried many things including deleting accounts and re-adding them, nothing seems to make a difference. Too be honest I've always been weary of my Godaddy email server, but I was not having this problem until upgrading to El Capitan. Please advise.

Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Thanks for the tip. I created a Bug Report for this (#24037724).

I have the same issue also. It appears to happen if I reply to an email before actually opening it. I can make the dot go away by switching to another folder and then returning to the inbox. It would be nice it it worked correctly thought!

Same problem here and it is a huge bug. It makes the mail not usable almost! I also wonder if this a problem from Microsoft's end but I think before the few last updates, it was working fine. So, looks like Apple needs to fix this.

It's a bug related to conversations. If I turn on and off View -> Organize by Conversation the blue dot unread indicator goes away.
