I am using EM Client version 9.2.2157 (5b49542) on Windows 11. Since two days ago, all Gmail accounts have stopped syncing - I get a red triangle next to the account head, which brings up a message saying “Connection failed: an attempt to connect to [email protected] failed. This could be caused by temporary server unavailability or incorrect settings. Please check the settings or click on the warning symbol to try connecting again.”
Other email services work just fine (e.g. Microsoft 365). For the gmail accounts, the calendar too seems to sync without any problem - it is only the mail that doesn’t sync. The mail works fine on other clients and web interfaces - only EM client throws up these errors. It is now over 48 hours since I started facing this problem.
I have already tried the following:
Deleting the gmail accounts and adding them again.
Uninstalling and re-installing EM Client 9.
Installing EM Client 8 (just in case the problem was with 9 alone).
For the gmail accounts, the calendar too seems to sync without any problem - it is only the mail that doesn’t sync.
As you already have the latest eM Client V9.2.2157 installed, then could be you may possibly have incorrect Gmail settings. Go to “Menu / Accounts” and “click on your Gmail account on the left”, and then “click the General, IMAP and SMTP tabs” to check the settings.
If you already have the same Gmail mail settings, then “might be some background program” possible interfering with the mail receiving.
Programs that can sometimes interfere are eg: Optionally installed Firewall / Security programs, Optionally installed Antivirus programs, Proxys and VPNS.
So if you have anything like that installed, try completely disabling those to test incase of interference.
Apart from that make sure when you add your Gmail account via the automatic account wizard that “at the end of the wizard” a browser appears to select your Google account and that you “click Allow” to give eM Client access to your Gmail account as per the following eM Client with Google workspace page.
I was having the same problem and had not encountered this with other email apps. I found that in the settings for my Gmail/Gsuite accounts I had to do the following for accounts I had already created. The issue was my VPN but this seems to have solved the problem.
Select Accounts from eM Client
For each Gmail/Gsuite account (and presumably any other accounts with issues)
Click on SMTP.
Change the port number to 465, and in the Connection Security line, select Force SSL.
