I’ve been experiencing freezing and unresponsiveness since installing yesterday. eM Client will work for some time but once I start interacting with it, it will freeze. This seems to occur after heavier use and also happened when it was downloading all my mail for the first time after installation. Killing the MailClient.exe process and restarting does not help; it freezes as soon as I relaunch it. Only a full reboot lets me use the software for a while until it repeats this cycle.
eM Client 10.4.4209 (d96494b)
Windows 11 Pro
Version 25H2
OS build 26200.7462
Windows Feature Experience Pack 1000.26100.275.0

If you have just installed eM Client and it’s freezing and it’s definitely not still synching your account folders, then it might be possibly eg: something running external to the mail client Interferring.
So first “click the dropdown on the right of Refresh” and click Show Operations and dblcheck if there is still anything initially synching. If there is wait till that completed and see if it then works ok.
Now “if there is definitely nothing synching and it’s randomly freezing”, then if you have any eg: optionally installed firewall / security program or optionally installed antivirus program or vpns “other than what comes default with your OS”, then try completely disabling those to test.
Next “If you have nothing optionally installed like that or you do but disabling them made no difference” then if you have a IMAP, Exchange, Office 365 or iCloud account, suggest to “Menu / Accounts” and try removing and readding your account again and see if that fixes it.
If it’s a POP account and you have already downloaded email and it’s no longer on the server, before removing and readding your account, “create a folder on your desktop” called eg: popmail, and “drag all your existing downloaded mail and mail folders into that folder”. Then once you are certain they are all there, remove and readd your POP account again via “Menu / Accounts”.
Then once your POP account has been re-added, “drag your desktop popmail back into the same mail folders” as you had prior to removing then.
Lastly if you have eg: Multiple accounts it might be freezing if you eg: have mail “that might be possibly corrupted within a specific account” so it freezes when it detects it. So if you do have multiple accounts, try adding them “one at a time” to see if it’s a specific account doing it.
I’m not able to show operations as the client is entirely frozen when this occurs. I only have one IMAP account (iCloud).
During troubleshooting I tried running em Client as administrator and enabled all logging. I also deleted a lot of emails. The client has been stable so far, hopefully this has fixed it.
I’m not able to show operations as the client is entirely frozen when this occurs. I only have one IMAP account (iCloud).
Then you might have a database issue, so suggest to next “close eM Client” and go to the following hidden database folder and rename it to eg: eM Client-Old.
(Windows hidden eM Client database folder)
“Users\yourusername\AppData\Roaming\eM Client”
Then uninstall eM Client and go to the release history page and re-download the latest version and reinstall and “setup as new” and see if it still freezes incase it was an installation issue.
If it still freezes then must be something going on either in the OS or with the computer in some way. One reason mail clients can sometimes freeze is eg: if your CPU is overclocked, so make sure that’s at normal speed if it is overclocked.
If your CPU is not overclocked, then I would next eg: disable all non OS user related optional programs on Windows startup and reboot to rule out any startup program interference. You can google how to do that if you don’t know.
Lastly sometimes programs can lock up if you eg: have outdated motherboard or videos drivers or outdated firmware etc. So make sure all your Windows driver’s & firmware etc is up to date.
Thanks for the info. I think I may have fixed the issue by disabling the GPU for eM Client. It has been running for a few days now with no issues.
For anyone having a similar issue, in Windows 11 go to System > Display > Graphics, create a custom setting for MailClient.exe (the default path is C:\Program Files (x86)\eM Client) and choose power saving for the GPU preference.
I also began to experience screen issues when waking the display from sleep where the login prompt would not show and the taskbar was busy after I managed to login. This seemed to occur when eM Client was left running. After some searching it seemed to be video driver related and I recently updated to the latest drivers, so I think there is an issue with the current version.
Thanks @AgileAntelope - I was experiencing the same eM Client freezes where I’d have to end task constantly, with all of the identical versions/updates that you listed. While it hasn’t been that long yet after making the GPU preference adjustment, eM Client normally would have locked up my PC by now.
I started to experience the freezes again. I uninstalled / reinstalled eM Client yesterday and used a new database. It froze while I left it running overnight. When I restart it reports database issues and fixes them. Not sure that to do at this point except wait until there are driver / windows / eM Client updates and hope something will fix this issue. I’m running a stock Dell desktop, no overclocking or anything out of the ordinary.
