I had to do a fresh install of Win 10 and eM Client to get the client to install at all. Is there a guide to importing the accounts, data and rules to get back to where I was before eM Client stopped working?
Have you been doing regular eMC backups?
Are you using IMAP or POP3?
If you have been doing regular eM Client backups in Win 10 either manually via “Menu / Backup” or automatically via “Menu / Settings / General / Backup” and have saved your harddisk profile "Documents folder to another internal or external drive (prior to reinstalling Win 10), then copy the latest dated backup.zip file from your saved “Documents / eM Client” folder to your new Win 10 same profile folder and then restore that backup in eM Client via “Menu / File / Restore”.
If you haven’t been doing eM Client backups, then if you have a copy of your entire harddisk (prior to reinstalling Win 10) on another internal or external drive, then you can copy the entire contents of the old eM Client hidden roaming database folder eg: “C:\Users\yourusername\AppData\Roaming\eM Client” and replace your current eM Client hidden roaming database folder with that one, which will also then restore your email how it was before.
Note: if you do restore your eM Client hidden roaming database folder, close eM Client first.
Lastly if you don’t have any backup or a saved copy of your entire harddisk prior to reinstalling Win 10, then (if you have an eg: IMAP, Exchange, Office 365 or iCloud account), just go to “Menu / Accounts” and reset up your account as new either using the automatic email wizard via “Add Account” at the top, or manual option very a “Add / Mail / Other” depending on your specific mail server. Your mail will then automatically restore after a short time from your mail server as it was before.
Thanks! I’ll give it a try.
