Mac mail login failed
today my Mac mail accounts all work, except one. I've tried to login with existing id/password (same as yesterday) but no luck.
Why? and how to proceed?
iMac Line (2012 and Later)
Question marked as
What company is the problematic email account with? (Apple, Gmail, Yahoo, other) Each email provider should have instructions for verifying/resetting your password if you've been locked out for some reason. I suggest using these articles and Apple Mail's Connection Doctor feature to help figure out where the problem is:
Use Connection Doctor in Mail on Mac - Apple Support
