Apparently, google depreciated one of its APIs, see:

https://code.google.com/p/google-apps-script-issues/issues/detail?id=5101

OAuth 1.0 is no longer supported and will be disabled on May 5, 2015. If your application uses OAuth 1.0, you must migrate to OAuth 2.0 or your application will cease functioning.

Hello Kerl, we’re using OAuth 2.0, so this issue shouldn’t be related to the API deprecation, what version of eM Client are you currently using, have you had any issues while authenticating with the mail server prior to this error?

Are you using any security software on your computer, that may have disabled the application’s ability to connect to the server?

If you’re experiencing this issue, can you please check your account settings in Tools > Accounts and possibly make a screenshot of your account settings and the general tab?

How did you setup your Google account with eM Client, did you use the automatic setup or did you import the account from another application? Have you tried to re-setup the account?

Thank you,

I used the eM Client automatic setup.  everything worked fine (for months) until yesterday afternoon.  I have not tried to set it up again.

Can you please make a screenshot of the account settings as I previously suggested?

Thank you,

Same problem on my side.
**Everything ok until yesterday

In my case resetup didn’t help. I’ve used automatic serup. eM Client have full permissions in Norton Security now. If NS is turned off the problem persists.

Same here with version 6.0.21372.0 (Dutch)

Same problem with version 6.0.22344.0.  Searching the web EVERYONE with gmail is having this problem.
