I shouldn’t have to shut down all my application manually before I shut the computer down for the night. If I trigger windows shutdown, you app should see that event and start shutting itself down before it releases that service.
When you shutdown, Windows just forces programs to close, but “does not automatically wait for them to close”. The open program / process just gets killed, so eM Client will then have to do an automatic repair on the OS restart due to the SQL mail database “was still open in memory” at the time, which then if that is happening alot can cause permanent corruption in your mail database leading to sometimes having to delete it and start again brand new. Some different type of programs might survive forced shutdown, but not eM Client.
So you have 2 options. Either “shutdown eM Client before you shutdown Windows”, or “shutdown in sleep mode”. Either way works for for me on Windows 10 & 11 and Mac OS Sonoma & Sequoia.
Also if you have a Windows laptop and normally slam / close the lid if your not using it for along time, “configure the OS to sleep rather than shutdown on lid closure” to avoid repairing as @skybat advised in his post in another thread.
