eMClient loses inbox entries

eMClient has begun to lose entries in the inbox. No error notification and the unread entries will just suddenly disappear from the inbox. They may return hours later while the junk folder will receive new entries periodically. The other way to get the entries back in the inbox is to exit eMClient, run CCleaner, and then re-launch eMClient. I have the app set to check for new mail every 5 minutes and another web based email client provided by my ISP gets mail quickly and doesn’t lose the entries. eMClient is v.10.0.3530.0 and is running on W11 v.22H2 bld. 22621.4249 with a 12th Gen Intel(R) Core™ i7-12700 @ 2.10 GHz & 16.0 GB (15.7 GB usable) & 1TB SSD. Any idea what’s going on with eMClient?

The problem continues and no response from eM Client support.

eMClient has begun to lose entries in the inbox.

Emails dissapearing in the Inbox. They may return hours later.

That’s very strange your Inbox emails dissapear and then sometimes reappear in the Inbox later.

As your emails appear online ok in your Webmail, I would suggest to then “try creating a new database to test” incase it’s corrupted in some way. To do that close eM Client and go to the following eM Client hidden database folder and rename it to eg: eM Client-Old. Then reopen eM Client and setup as new and see if that fixes it.

(Hidden database folder Windows)

Windows hidden eM Client database folder)
“Users\yourusername\AppData\Roaming\eM Client”

Now if the new mail database still has email randomly dissapearing and reappearing from the Inbox, try next uninstalling eM Client and “delete the database” when asked on the uninstall wizard and then re-download eM Client V10.0.3530 from the release history page and reinstall as new.

Also recommend after reinstalling “for a test to disable the Inbox Categories” so everything then goes in your Inbox. To do that go to “Menu / Settings / Mail / Categories” and disable Show Categories and then Save & Close settings and then see if all your emails stay in your Inbox

Now if your Inbox emails still randomly dissapear and then reappear later, then there must be something outside of eM Client causing it. You might then need to test with a “new Windows user profile” and see if that fixes it

The other way to get the entries back in the inbox is to exit eMClient, run CCleaner, and then re-launch eMClient.

I would avoid running CCleaner “while you are troubleshooting eM Client” as those type of programs can sometimes delete registry entries and files that eM Client might need to work.

Thanks, but what file/folder to rename or do that to the entire emclient folder? There are dozens of them in the emClient folder.

You rename the actual eM Client folder itself.

So that folder will then show as eg: “Users\yourusername\AppData\Roaming\eM Client-Old”

Dont rename any of the files inside it.

OK, still no improvement after your rename and still no fix. I ran the database recovery command and it did not fix the issue, but there doesn’t seem to be any issues with the application files themselves. I downloaded the app and attempted to run the repair funtcion, but it fails every time about 2/3ds of the way through. It’s strange, but the display will show a complete inbox content and suddenly half of the entries will just disappear. The newest half. Later on, they will return after the program has refresed itself a few times. Meanwhile, the junk folder will have accumulated several entries. This problem started with the lastest automatic update. Is there any way to remove, or back out the latest update?

The newest half. Later on, they will return after the program has refreshed itself a few times.

After renaming the old database and reopening eM Client, when you re-setup your accounts, did you try “Disabling Categories in Settings” to then see if the messages that suddenly disappeared then showed back in the single Inbox ?

Also did you look in the “Favourites / Unread folder” at the top left to see if the dissapeared messages then all showed in there ?

Also have you tried uninstalling eM Client and deleting the new database and reinstalling the latest V10 again via the release history page and setting up brand new ?

If you did try disabling Categories and “none of the disappeared Inbox messages” are showing in your account Inbox, or showing in the Favourites / Unread folder, or showing in the Junkmail folder with a brand new install and new database and no rules or blacklist setup, then sounds like to me as previous surmised, there is eg: something either outside of eM Client on the computer running resident causing this to happen, or possibly a problem with your current user profile being your webmail is showing all the Inbox messages ok.

Is there any way to remove, or back out the latest update?

What version of eM Client did you have previously where the messages didn’t disappear ? Was that only when you had V9 or was it a previous build of V10.

The prior version was whatever version 10 was before V10.0.3530. Just now, I launched eMClient and all of this afternoon’s emails were missing from the inbox list. The morning emails were there, as they have been all day. Of course, the app immediately began a refresh and all of the rest of today’s emails popped up in the inbox before the refresh finished, but there were 9 new emails in the junk folder. Favorites always matches the inbox. The fact that no emails are ever lost, just very late in eventually showing up is good. I wonder (and this is a stretch), but could the current version of eM Client have issues working with the 1TB SSD that is drive C on this system? Thanks for your help,

Ok to try the older V10.0.3447, you can then again uninstall your current version and “don’t delete the database” when asked on the uninstall wizard.

Then close eM Client and again rename your new eM Client hidden database folder to eg: eM Client-Old-1 and then download V10.0.3447 from the release history page and reinstall. Then open eM Client and setup as new again and see if the emails then stay in your Inbox or suddenly dissapear.

If it then works ok with the older version, backup eM Client first via the “Menu / Backup” and then try upgrading again to the latest version.

However if it still happens with the older version V10.0.3447, then close eM Client and “delete the database” when asked on the uninstall wizard and then download the latest V10 again. Then reinstall eM Client V10.0.3530 and “skip the initial setup wizard” and then when eM Client opens, close eM Client. Then delete the new eM Client hidden database folder and rename your latest eM Client-Old-1 hidden database folder back to eM Client and reopen eM Client.

I see to you are currently have W11 v.22H2 bld. I would also suggest to “try updating to 22H3 bld” which had alot of fixes and updates etc which was pushed out late last year. That should already be available in your Windows updates. If it’s not suggest to contact Microsoft for assistance.

Could be something in the old Win 11 22H2 build causing it. So just a thought to try that too.

Could the current version of eM Client have issues working with the 1TB SSD that is drive C on this system ?

No the hard-disk type has nothing normally to do with that. SSD and M2 (Solid state drives) are just alot faster to read data compared to the old IDE or Sata mechanical drives.

If I run “repair” on the inbox folder, the missing emails will reappear immediately. Later, they may disappear. This issue definitely started after the last eM Client update. There have been at least two Windows Updates since the issue began and it began some time after a WU as I had WU paused for while. At least now I can get the missing emails back at will and not have to wait for an update or blind dumb luck to find them. Thanks again for your help. Jim

If you are running the manual eM Client database repair via the command line and emails reappear afterwards, then that usually means your previous database in V10.0.3447 was eg: “possibly corrupted in some way” so when you then upgraded to the new V10.0.3530 which also then upgrades the database again, it may have caused this issue with the messages dissapearing.

However if recreating a new test database in the new V10.0.3530 made no difference, then it normally points to something outside of eM Client. Hopefully though V10.0.3447 works ok.

There have been at least two Windows Updates since the issue began and it began some time after a WU as I had WU paused.

I would recommend to not pause Windows OS updates / patches for too long as there can be eg: big security risks doing that. Also sometimes if you delay them too long “they can then sometimes eg: dissapear from the OS automatic updates” and you then have to manually find & download separately, which can then be complicated depending on your computer experience.

I have run the “C:\Program Files (x86)\eM Client\MailClient.exe” /dbrepair command from the CMD line to fix corrupted junk folder entries, but it has had no effect on the inbox folder. To fix the inbox missing entries, I right click the inbox folder, select properties on the popup, and then select the “repair” tab, followed by the “repaiir” button, and OK. This restores the contents of the inbox folder for awhile. Eventually, roughly the later half of the inbox enteries will disdappear while the application is not on the screen. I have eM Client set to refresh every ten minutes and sometimes it will fail to complete a refresh. That seems to be when it loses some of the entries in the inbox folder. I think I will just wait for the next update to see what happens, since I can manually repair the folder at will.

You shouldn’t need to keep repairing your database. So either your current database is corrupted in some way, or something outside of eM Client is causing that issue.

Did you try completely uninstalling eM Client and deleting your current problematic database and then reinstalling either “your previous V10.0.3447 or later V10.0.3530 version” and setting up new to test as per my previous instructions?

I have done everything you suggested to no avail. I was unable to go back a version because the database was by a newer version. I believe the database is corrupted in the inbox as no other folders have the issue and there doesn’t seem to be any way to clear that up even when the inbox is empty. I have discontinued using eM Client, but kept it installed as the database contains mail I wish to keep andI haven’t had time to secure it elsewhere. I have eM Client backups, but I’m guessing they are corrupted also. I have not uninstalled the app and will see if future versions correct the inbox corruption. I never received a reply from eM Client support either. Thanks for the help. I will close this thread.
