I always get error message when I try to save above settings “Invalid email or password”

@LifeP, do you mean like instead of seeing the entire email address you only see the alias? If it is, I am not sure but maybe @Muzzy can help out on this.

@Amarjeet_Singh_Sintu, then you should probably confirm the email address and/or the password. If you follow these instructions in detail, it should work.

@kenince thanks lot it works :grinning:

edit: be aware of usage limits like login frequency to sync mail Usage limits  |  Gmail  |  Google Developers

Alternatively, one can use the app-password setting.

I couldn’t get the above to work on a standard free gmail.com account, but the app password one worked. You do need to set up 2FA.


Thanks. It worked perfectly
