Hi,
I've just added a new gmail account to mail apps and since then it's not working anymore.
All my mails and documents are stored on this app.
With other profile on my Imac, Mail is still working.
All softwares are updated. I performed some basic checks/repars with Mac Utilities and MacKeeper.
Some info:
Logiciel Mac OS X Lion 10.7.4 (11E53)
Thank for your help!!!
Stephan
