Mail: cannot reply to messages.

iMac 21 inch late 2012. OS X El Capitan.

Mail: Since yesterday I can't reply to messages. First the reply button didn't work. Then I used the right click to reply but now that doesn't work either. An empty mail window appears but I can't do anything with it, not even close it.

Any suggestions? Thnx!

iMac (21.5-inch, Late 2012), OS X El Capitan (10.11.2)

Hi, A.Visee.


Thank you for visiting Apple Support Communities.


It sounds like the Mail application becomes unresponsive. I would start with forcing the Mail application to close and open the Mail app via the steps below.


Force an app to close on your Mac


Open Mail and immediately hold the Shift key until Mail opens. This causes Mail to open without any message or mailbox selected.


If Mail unexpectedly quits when viewing certain messages


Cheers

This same issue has been occurring for me since I upgraded my Mac Pro from Mavericks to El Capitan.


Apple Mail seems to function ok, apart from when I try to reply-to or forward mails. If I try either of those actions from an existing message, I get a blank compose window which I can't interact with. The blank window cannot even be closed, which requires a force-restart of Apple Mail to get rid of.


My mail is configured to use IMAP, but is set to store draft messages locally.

Hello,


I've been having the same problem with Mac Mail since upgrading to El Capitan.


I have about 10 email account and this problem only seems to affect the IMAP accounts.


The only way I can reply to or forward a message is to create a new blank message, copy and paste the contents of the email I want to reply to or forward into the new blank message, add the subject line and add the recipient's details manually.


I shouldn't have to do this and it was fine before the update.


Any help would be appreciated.


Many thanks.

Thanks for the details about Trusteer Rapport, which I do have installed and running with Firefox.


I'm going to start by just turning Block Screen Capturing to "Never", under the Security Policy tab, but if that doesn't resolve the issue, then I'll just "Stop Rapport".


Hopefully this will do the trick! 🙂

Apparently the best thing is to get rid of it altogether by using the Uninstall in rapport.dmg:

"It is a modification to OS X that will result in random crashes and generally unreliable behavior. It will achieve the ultimate in computer security, which is to render your own computer effectively unusable. The bug is not in OS X. The bug is "Rapport". Get rid of it. Do not install anything like it ever again."
