eM Client often crashes when trying to open an event in calendar

eMC v8.1.1060 W10

For an unknown reason, eMC crashes when I try to open an event in a calendar (by double clicking or by right clicking then Open). This behavior seems to occur randomly, maybe once in every 2 to 3 similar actions. It affects events set by others as well as events I set myself.

I tested this behavior over the course of a week (the problem arose with my upgrade to v.8.1.160) and I couldn’t notice any given pattern: crashing will happen with all kind of events (set in eMC, in Google Calendar, in Zoom, in Zoom with the Google Calendar add-on, etc.).

And each time, eMC closes and checks the database (which never contains any error). I did a clean reinstall of eMC but it didn’t change behavior. Crashing still happens several times a day.

The error output I was about to copy and paste here contains 234 pages! I sent it numerous times to eMC and explained this odd behavior. I’m just waiting a bit before contacting support, hoping a user here might have an ‘easy fix’ .

Any one is experiencing this issue?

Am I the only one with this issue?

I am trialing emclient at the moment , just installed the latest version yesterday and the same issue has happened to me several times today - exactly as you describe. I sent a message when requested.

Any help appreciated.


I opened a ticket with support yesterday. I’ll keep you updated.

Yes i too had eM Client creash back to the desktop once today when i tried to open a Gmail Calendar event by dbl-clicking it. I got the restart emc message and to send the error report which i did.

Using EMC V8.1.060 for Windows

I encountered this issue too for a couple of months. The latest crash yesterday on v8.1.1060. It doesn’t occur too often.
Sometimes the Event Description has been lost or not synchronized to mail server. I use two computers and sometimes Event Description created on one computer has different (truncated) content on the other computer. As I said, it occured rarely. I haven’t seen it until 8.1.1054

Thank you @Moss, @cyberzork, and @Vladimir_Losinsky. Support team has a link to this thread so I hope they’re monitoring it.

Thanks for the update

This happened again this morning when dbl-clicking a Gmail calendar event, and i have the crash error report in notepad, but cannot paste it in this thread as says “Its too long” to paste in (more than 3200 char). I wonder if there is an email address I could send it too as an example ?

You don’t need to email it (when I copied the error log to Word it took 235 pages!). If it happens again just send the error report after the restart eMC message.

If ever you have a pro account it would be great if you too could open a ticket about this issue. I have no doubt about eMC technical team handling my request seriously but I just want to let them know this is not an isolated issue.


Ok I’ll just keep clicking the send error button.

I forgot mention, that my calendar is not Gmail. My calendar is (CalDAV account) on Kerio mail server.

No, I just posted the same issue, amongst other issues.

Thanks, I saw your other thread few minutes ago.

I now try to right hand side click /open until a solution is found.

In my case it crashes even with that method, unfortunately.

We tried to reproduce the problem but to no avail. Could you either post here the full error report or send it directly to me at wilson@emclient.com, please? Simply click the button “Show error” and attach the log to your reply.
Thank you.

Thank you @George_Wilson. I’ll send the error log to your email in few minutes.

Edit.: Done.

To all: We’ve fixed this issue so you can download and install the updated version of eM Client from here: https://www.emclient.com/dist/v8.1.1087/setup.msi

Please let me know if it helped.

Edit: Updated link


So far so good with the V8.1.1084. No crashes yet dbl-clicking any Gmail Calendar events :slight_smile:
