Since about a week eM Client (v8 Pro) crashes multiple times a day. Most of the time when trying to delete one or more emails.
If its happening alot deleting any emails, then sounds like your local mail database account might have possibly become corrupted, or maybe something has happened with eM Client itself.
So i would first try first forcing a repair of the mail database manually via the command line.
(Force a repair of the eM Client database manually for Windows)
Close eM Client and then open a Windows Command Prompt. Not a Powershell, Then Paste and run the following command:
“C:\Program Files (x86)\eM Client\MailClient.exe” /dbrepair
(Force a repair of the eM Client database manually for Mac)
Close eM Client and then “open the Terminal app via either Launchpad or Utilities” on the Mac. Then Paste and run the following command.
/Applications/eM\ Client.app/Contents/MacOS/eM\ Client /dbrepair
Now if the repair makes no difference, suggest to next try “removing and re-adding your account”.
So If it’s an IMAP, Exchange, Office 365 or iCloud (Non POP account), go to “Menu / Accounts” (PC) or “eM Client / Accounts” (Mac) and remove and re-add your account using either the regular “Add Account automatic wizard” at the top, or the manual “Add / Mail / Other” account option depending on your specific mail server requirement’s.
Now if its a POP account, first create a folder called eg: Old Mail down in “Local Folders” at the bottom left of eM Client and drag / move all your current messages and message folders as they are down under Local Folders. Then once you are certain all your current POP mail is under Old Mail, then remove your POP account at the top and then re-add it. Once its re-added again as new, then drag / move backup all your old POP mail from Local Folders to the matching new POP mail account.
Note:- If you don’t see Local Folders at the bottom left of eM Client, go to “Menu / Settings / General” (Pc) or “eM Client / Preferences / General” (Mac) and check the box “Show Local Folders” & Save settings.
Apart from that you might need to uninstall eM Client and delete the database and reinstall from scratch. Hopefully though the manual database repair or removing and re-adding of the acct fixes it.
Lastly if you get it then working ok with either of the above methods, then create a backup of eM Client via “Menu / Backup” (Pc) or “File / Backup” (Mac) so you can then easily restore if need be in the future. You can also setup automatic periodic backups via Settings / Preferences / General / Backup.
