Mail quits as soon as it starts
Hello,
On my Macbook Pro running with El Capitan, Mail suddenly to acted up and quits now every time I try to start it. The error message says :
Crashed Thread: 0 Dispatch queue: com.apple.main-thread
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000018
Exception Note: EXC_CORPSE_NOTIFY
I tried a few things already but nothing seems to help.
Any input would be very welcomed.
Thank you.
MacBook Pro 15″, OS X 10.11
