Under event settings in Google calendar settings, I selected ‘From Everyone’ and it now syncs fine between em Client and Google calendar.
Hurrah!

Cool! We’ll add this info to our knowledgebase. Thanks everyone for opening and sticking to this topic, and shoutout to our developer for figuring it out 
This is a serious security issue. “From Everyone” is a really bad idea.
Bad agents are sending phishing invites that will automatically be added to your calendar. We had an issue in our org with this and have to change to the “when I respond to the invitation in email”. Unfortunately since the bad actor invite was automatically accepted once, the account is now getting bombarded with spam invites. I highly suggest you change that setting.
Its only an issue if you accept a calendar invitation. If you don’t know them delete the invitation. Same goes with any emails you have to be aware of phishing email these days & delete them. The mail client carnt be held responsible for that. Its all about user education with emails.

Just put a block on the sender.
I wish that were the case. If you have “from everyone” the invite will be placed on your calendar whether you accept the invite or not. This is part of Google’s ‘smart features’ but if you disable that, then you lose out on a lot of other beneficial things. The only alternative I’ve found from that is to use known or when you reply to invite.
As far as blocking the sender, Of course we do, but it’s almost futile as the email and domain is basically randomized and they don’t use the same one twice.
Edit to add a reference (is this allowed?) from folks who can explain it more eloquently than I:

Otherwise just google the subject and you’ll see what I’m talking about.

I wasn’t aware it did that.
Yes you are correct that it adds the event automatically to the Google calendar “as soon as I received the email” without accepting the invite from further testing and it creates a public event.
Even creating the event as private in eM Client mobile app doesn’t make any difference.
@Kim_Fisher Can the devs look at this again to make it work with setting Google calendar settings to “when I respond to the invitation in the email” or “only if the sender is known” to fix this issue.
Hey, we appreciate the concerns you’ve brought up and are currently reviewing it.
Hey all, I’m sorry to say that we simply cannot do anything about this. Our developers have thoroughly explored it, but it is a Google limitation and we haven’t been able to find a way around it.
Re: the security issue, though. I don’t mean to trivialize it, but I want to stress this only comes up if yes, you actively interact with these invites – as is the case with spam emails after all. The rule of thumb: identify phishing attempts, don’t interact. Again, I really do empathize with cases where one might accidentally interact with such an invite, and if you ever start getting an onslaught of fraudulent invites, I understand you might want to consider whether the setting for the sake of syncing invites is worth it. But I do consider it a hypothetical, and again, our hands are tied in this case.
Thanks for looking into this issue. At least we can now get invites synced online this way and hopefully Google will update this in the future.

I actually looked into Thunderbird over the past 2 weeks. It’s pretty good, but it just does not have the same smooth coupled interface like most of the other email clients. I think that’s the trade-off with being able to customize it so much. Also it had it’s own limitations like meet/zoom integration directly in the invite and other calendar functions that took extra steps to perform, so I didn’t find it worth switching.
Basically every tool is going to have some limits so if we can get to 90 to 95% of the way there, I think that’s realistic.
So back to emClient and trying to figure out how to not have calendar entries disappear after I accept them 
I have From Everyone set and the calendar invite still does not work correctly. To reiterate, it is when I accept on Windows desktop emClient (v.10.4.4209) and it does show in my emClient, but never syncs to google which I verify by going to calendar.google.com in my browser.
This is a major issue for me as I get invites and updates to invites constantly and I can’t manage them within emClient.
Hopefully there is a solution or work-around that will fix it for me.
My work around is to accept the invitation on my phone using Gmail.
The only emClient work around I found was to accept it, then accept as tentative then accept as normal again.
No idea why that worked. Bit of a faff tbh
Did you get resolution on this. I’m experiencing a very similar issue. When accepted in Google Calendar invite syncs to EmClient. When accepted in EM Client, calendar invite does not sync to Google. I’ve been able to successfully add some of the invites to my calendar by going back to email with them, but not all.
I have From Everyone set and the calendar invite still does not work correctly.
That setting Everyone does work for me personally synching calendar invites from Android to iOS or iOS to Android and updates in Google calendar online within a few seconds.
Don’t know why it’s not working for you.
Maybe try “if you haven’t already” power off and on your mobile device and disable and re-enable your mobile cell data or wifi. Failing that suggest to uninstall and reinstall the mobile app again and reimport your desktop settings via QR Export.
To reiterate, it is when I accept on Windows desktop emClient (v.10.4.4209) and it does show in my emClient, but never syncs to google which I verify by going to calendar.google.com in my browser.
If you are accepting calendar invites “in eM Client for desktop” and its not synching to your Google Calendar online but the invite does show accepted in eM Client, then could be you have something eg: running resident blocking or interferring with the synching to Google online.
Programs such as eg: optionally installed Firewall / Security programs or optionally installed Antivirus programs or vpns can sometimes interfere with Mail Clients syncing. So if you have anything like that installed “try completely disabling those to test” incase of interference.
If you have no optionally installed programs like that or you do but disabling those made no difference, “then try resetting the Windows builtin firewall to default settings” and reboot your computer and see if that then syncs the desktop calendar invites.
