Recover account difficulty
I just found this, which does not work on my personal device (permission denied, not rooted).  Will try again on the affected user's device.

This gives a path: http://forum.xda-developers.com/showpost.php?s=36bdbe78a049f9e358a0421113d922c2&amp;p=54912072&amp;postcount=7


  Browse to /data/user/0/com.android.email/databases and copy EmailProvider.db to your computer. Other phones might have their database in a different location. Download and install Sqlite Database Browser from sourceforge.net if you haven't, and then skip down to the sqlitebrowser instructions here:


This gives instructions and a different path (presumably because of different Android version): http://ubuntu42.blogspot.fr/2011/11/android-recover-mail-password.html

Summarized:


adb pull /data/data/com.android.email ~/email_of_phone
sudo apt-get install sqlitebrowser
sqlitebrowser
