Mail

Hello,
I’m trying to set up my GMail account.
But I get the error message that OAuth isn’t working.

I have already tried the following:
Antivirus deactivated… error remains the same
Firewall deactivated… error remains the same
Restarted PC… error remains the same
Reinstalled eM Client… error remains the same
Used another browser (Chrome, Firefox, Edge)… error remains the same
The error message appears immediately after I have carried out the authorization in the browser.
Any idea ?

Try closing eM Client and then go online to your Google Account Connections / Third Party Apps and if there is any existing eM Client Tokens, remove them, and then close your browser.

Then open eM Client and try setting up again via the automatic account wizard.
