Google Calendar will not sync, it continuously asks for user name and password

Calendar will not sync, it continuously asks for user name and password.  I have allowed cookies… I have restarted… I even tried to enter my AOL password just in case that is what the Pop-up was asking for.  (My Email is set up through AOL only.)

I use to use Outlook, but it was frustrating me for a number of reasons.  I have long been using Google Calendar to sync with my phone and also my home computer and Outlook.

See Screen Shot (I did “edit” my Email for privacy reasons… it didn’t have the address blacked out or with ****)

Hi Steven, I’m a little confused which accounts are you having issues with. You’ve mentioned an issue with Google account, but on the screenshot I can see @aol username. Can you please make a screenshot from Tools > Accounts > Your probleamtic account?

Also what version of eM Client are you currently using?

Thank you,

Hi I had the same problem. and it was solved by lowering the security setting of my google account. I got an email on my google account, saying it was accessed and blocked. In that email there was a link I could lower my security setting. after that my calender worked fine.

good luck :slight_smile:

Hi Sterre, I was notified by the developers that this might be an issue sometimes since eM Client is using some older methods for authentication.
Thank you for sharing your solution, let us know if you come across any other issues or questions, we’ll be happy to help.

Thank you,


I am currently evaluating emClient for use in the company I work for. We are also experiencing this problem but we are not exactly keen on lowering security.
Can you explain what actually goes wrong? Are you planning to solve this issue?

Kind regards,

Hi Frank, I completely understand, however please note that the setting is (aptly) called, less secure… However the setting is related to use of some older authentication standard, but I can assure you there’s no security risk in enabling this option for use with eM Client, however we do understand this may sound bothersome for some of our users and we’re working on improving the authentication with google’s servers for future releases.

Thank you,

Hi Paul,

thanks for  the incredibly fast response. :slight_smile: Do you have any further reading on this topic? What are the differences between the authentication standards?

I probably won’t be able to argue changing that setting without any further details. Of course I tried to google that topic before I posted here, but I did not find too much useful information.


Hi again,
it’s actually very simple, the less secure apps option enables you to login using your password, what “very secure apps” would mean, would be using OAuth for authentication. OAuth, redirects from the application to the website, where it receives a token and redirects the token back to the application, allowing you to login.

So as you can probably tell, this does not necessarily mean the application is not secure.

Hope this helps,
