I am with I am with El Capitan 10.11 Beta (15A263e). I just cannot open the preview pane in Mail, the bar won't go up in classic view, and there is not a vertical bar in the other view, any clues to solve this? Already reinstalled OX, but...
Mail preview pane won't open
Hi Neuding,
You can diagnose if this being caused by an issue with one of Mail's resource files by forcing Mail to rebuild them (this has nothing to do with rebuilding a mailbox). Quit Mail and move the following folder to the desktop (you can press shift+cmd+G from Finder and copy-paste if you need to):
~/Library/Containers/com.apple.mail
Restart your Mac. Open Mail again and, hopefully, the issue won't reoccur.
