Cannot sync with Google

It is only needed for the account authentication after removing the third party access permissions, as it may have something to do with your browser settings in Firefox. Once everything is working, you can go back to your preferred browser.

oh, good to know. This has happened quite a few times where eM Client stops syncing with Google, but usually if I reboot my computer it fixes it. Just this time it didn’t, but changing the browser worked a charm. Thanks again!

Changing browsers didn’t make any difference, nor did I think it would. I have already added 18 accounts using my default browser, Chrome, before trying to add another Gmail account today. But, for the sake of argument, I set Edge as my default, then tried Firefox, results the same, so browser is not the definite answer.

Also tried to uninstall and reinstall eM, that didn’t help either and now I’m stuck and unable to add any emails, so I went to the backup.

Also uninstalled my anti-spyware and disabled Windows Defender and made sure there are rules in my firewall to allow all connections from eM, although this is a useless because as I mentioned, I already had 18 accounts I successfully added manually.

Okay, so it’s almost a month later, and the same thing has happened–eM Client has stopped syncing with Google. Do I have to go through that whole thing again by removing account access? I had already switched to Chrome as the default browser, so I’m not sure what to do at this point. It’s so frustrating that this keeps happening.

I have the same issue today Jean. Frustrating it is. I am on Chrome, have always been, but never had the issue before. The only thing that has happened this morning was my AVG Free updated.

Completely disable AVG and see if there is any difference.

Gary, I’m sorry you’re also experiencing this frustrating glitch! I don’t have AVG, but I disabled Norton 360, refreshed eM Client, but still no sync. I then completely shut down my PC (that had worked in the past), rebooted, left Norton disabled, but still no sync. Let me know if you can think of anything else to fix this. Thanks!

Mine is working again:

  1. Removed eM Client access to Google
  2. Changed default back to Firefox from Chrome - allowed access to eM Client
  3. Rebooted computer
  4. Sync did not work
  5. Removed eMClient access to Google
  6. Changed default browser to Chrome
  7. Launched eM Client. Allowed access to eM Client
  8. Sync worked one way–I could enter event in eM Client and it synced to Google calendar, but event entered into Google calendar did not show up in eM Client.
  9. Tried rebooting again. eM Client syncs both ways with Google calendar again.

Thank you Gary, apologies been out with family whilst waiting for my weekly scan to finish.
I disabled AVG, closed eMClient, reopened it, refreshed sync, all working spot on.
I then enabled AVG again, and lo and behold, all working and syncing as it should.
Thank you and appreciated for your help.

Well done Jean, good to hear and well done, as Leader Gary suggested, I disabled AVG, closed and re-opened eMClient, sync worked on refresh, now still working even though enabled again. Thank you.

I am so frustrated with eM Client right now! Just 19 days ago I had this same problem, and here it is again. My Google calendar is not syncing with eM Client. It keeps happening over and over again. I removed permissions, changed my browser, re-allowed permissions, rebooted, and still no sync of my calendar. I have already missed an appointment because it wasn’t syncing. Is there anything that will permanently fix this problem?

Last time I had the issue, changing to a different browser worked, but this time it did not, and I can’t get my Google calendar to sync no matter what I do.


My Google calendar is not syncing with eM Client.

Try repairing Google Calendar as per my post at the end of the following Thread.

Sync gmail calendar - em Client - eM Client

I just started having this problem yesterday, Thursday, September 15, 2022, I’m in eastern USA. I use the Avast anti-virus program. eM Client was failing to sync with Google, and also with two other email accounts I have, all IMAP: and I first followed the steps listed here, removing my eM Client account from Google, then restarting eM Client. I got the popup in Firefox from Gmail asking me to authorize eM Client. I did that. Still, syncing not working on all 3 accounts. So, I temporarily stopped all the shields in Avast. Upon restarting eM Client, one outgoing email to my Gmail account got sent, and the freeshell and 1-voip accounts now synced. But still, Gmail will not sync my inbox or other folders that contain incoming mail.

I have the Evolution email client configured in a Linux VM. I just started that, and it is syncing with Gmail without issue. So this is an eM Client problem only.

[EDIT 9/17/22] Today, both my Google and other email accounts were again failing to sync. Knowing that temporarily disabling Avast anti-virus at least allowed the other account to sync, I again disabled Avast and clicked Refresh in eM Client. All my accounts successfully synced, including Google. I opened a ticket with eM Client - I bought a lifetime license. I’ll update that with the observation that for me at least, this appears to be a conflict with Avast. For those using AVG, note that these two merged awhile ago, so they’re basically the same now. Hopefully this will help somebody.

[EDIT 9/19/22] I finally got eM Client working again, with all Avast shields running. I had to change my account settings from:

port: 993
security policy: Use SSL/TLS on special port (legacy)

port: 587
security policy: Use SSL/TLS on special port (legacy)

Email receipt works fine with these settings, but sending was failing. I changed SMTP to:

port: 587
security policy: Force usage of SSL/TLS

And now I’m able to send and receive again. I opened a ticket with eM Client, after spending the $10 for the privilege, but was essentially told “talk to Avast, this is their problem”. I figured this out myself. I doubt I’ll get my $10 back.

I needed help to recover from eMC’s cock-up of a few weeks ago. This latest failure is totally inexcusable, so I am uninstalling the program and going elsewhere for my e-mail service.

Cyberzork, after spending over an hour yesterday removing my eM Client from Google, changing browsers, rebooting multiple times, and re-adding eM Client to Google, it finally started syncing again. If this happens again–and I’m sure it will–I will try repairing Google calendar.

My main concern with this issue is that there is no way of knowing it didn’t sync unless I happen to go directly to my Google calendar and see that there are entries that are not on eM Client. My husband shares his Google calendar with me, and that was the only reason I found out that it wasn’t syncing. I happened to look at the Google calendar on my Android phone, and saw that he had entered appointments that did not show up on eM Client. In the past when this happened, I have missed appointments. So embarrassing to have to tell people that it wasn’t my fault–it was my calendar’s fault. “Yeah, sure it was,” they think.

Big66Bumble47, what e-mail client will you switch to? I also looked into other clients, but to be honest, it looks like all of them have issues and complaints. I really love eM Client when it works, but I, too, am looking into other options. I haven’t found one that seems to have the same features as eM Client, though, and I’d rather not switch if eM Client can only get this issue resolved. Which one will you be using?

Hello Jean,

I have switched to Yahoo Mail. This seems to work OK (so far!) although I do receive a few unwanted advertisements. Good luck.


Big66Bumble47, thanks for that info. Yahoo won’t work for me. I like that eM Client has Mail, Calendar, Contacts, and Tasks. I love everything about eM Client–except that it keeps having these problems that never seem to get fixed.

Those are the exact settings I have been using, but my calendar still is not syncing with Google. I am really ready to scream. I have gone through these hoops so many times, and it eventually starts syncing again after multiple changes of default browser, rebooting, etc., but then in a matter of hours or days, it stops syncing again. Repairing the calendar did not make any difference.

Does anyone have a permanent solution to this? Thanks.

I just verified my calendar is syncing. I had just entered a new event via my cell phone this afternoon. After reading your message, I see that the new event is showing on my eM Client calendar.

You’re correct, these repeated syncing problems are annoying. Hopefully, mine will be stable for a long time. Unfortunately, I don’t know of a better email client with IMAP email, calendar and contact syncing with Gmail. Up until 8 years ago, I was using ThunderBird and was happy with it, but then it corrupted a calendar at work. :frowning: That’s when I switched to eM Client. So, I guess none of them is perfect.
