I was using davmail in servermode for more than 3 months without any problem, everything working perfectly.
Now, it's been 2 days since davmail can't authenticate to the exchange, and I can't identify what the problem is.
No configuration was changed in those days, nor user password (same version of Java and DavMail).
The server is running on a linux, in headless mode
I tried to update DavMail to version 6.1.0 (before it was 6.0.1), but the error persists.
....
Update:
Sorry, appears to be a problem with a local certificate (even if it is not expired)
