I'm attempting to connect my zoho email address to my gmail account (so I can send emails from hello@therethere.eu via gmail).

I entered all the info provided and no matter what I do this is the error message I get from gmail:

Authentication failed. Please check your username/password. [Server response: 535 Authentication Failed code(535) ]

I have attempted to switch on the two factor authentication and use an app specific password - didn't work.

I then disabled the two factor authentication and tried with my standard password - still getting them same error.

Any ideas on what I might be doing wrong?

Thanks

Bojana
