Cannot connect Mailstore to Comcast. No matter how I try to connect the error is the same: Authentication, check the account and password. The server returns LessSecureAuthDisabled (NO)
You already know the reason,so go to the source.
Since I don’t use Comcast I can’t get into security, but you should be able to.
(Can’t say much about the graphics on that page - too small to be of much use…)
Turning on Less SecureAuth should hopefully resolve your problem…
