I cannot access Mail at all. The app seems to open but I no viewer (inbox etc) comes up so I cannot see any mail whatsoever. The provider is OK as I am receiving and sending mail on my iPad and iPhone. Any suggestions. El Capitan is up to date as is M

Please quit Mail. Force quit if necessary.

Back up all data before proceeding.

If you're running OS X 10.11 ("El Capitan") or later, triple-click anywhere in the line below on this page to select it:

~/Library/Mail/V3/MailData

If you're running an older version OS X, use this line:

~/Library/Mail/V2/MailData

Copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go ▹ Go to Folder

from the menu bar. Paste into the box that opens by pressing command-V, then press return.

A folder window will open. Inside it there should be files with names as follows:

Envelope Index

ExternalUpdates.storedata

Move those files to the Desktop, leaving the window open. Other files in the folder may have longer names that begin as above. Move those files, if any, to the Trash.

Relaunch Mail. It should prompt you to re-import your messages. You may get a warning that the index is damaged and that Mail has to quit. Click OK. Typically, the process takes a few minutes, but it may take hours if you have gigantic mailboxes. In that case, you may be able to speed things up by temporarily adding your home folder to the Privacy list in the Spotlight preference pane. Remove it when Mail has finished importing.

If the import operation stalls or fails with an error message, quit Mail, delete the two new index files (keeping the original ones that you moved to the Desktop), and try again. According to many reports, the second attempt may succeed after the first one has failed.

Test. If Mail now works as expected, you can delete the files you moved to the Desktop. Otherwise, post your results.

I tried this twice, but got a Mail quit unexpectedly after a Menu -> Message Viewer:

Hi Linc,

Had the same problem today after using a postcard from the stationery...

I followed your hints and after redoing it for the fifth time it works again.

Thanks a lot !

Marc

Didn't work for me even after 5 attempts, anyone for an alternative solution?

Mine hangs 3 messages short of importing all the messages - have followed the suggestion 2x so far and will go to six times before I give up. My iMac is running 10.11.6 El Capitan and is 5 days old. I would love if Apple could release a patch to resolve this considering the issue is a year old.

It seems to get hung up creating Envelope Index-T0x7fa296139d90.tmp.EcSnNX-wal and it never actually makes a new External Updates file.

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it. A new post would be much more visible. You can link to this one.

I have the problem of Mail quitting immediately after it opens. I've tried everything, disc utility, restarting over and over, quitting Mail and reopening. Nothing works.
