Hi,

since my upgrade from Windows 7 to Windows 10 I have the problem, that in 80 % of the time after sending a mail. Thunderbird is "not responding" for a minute or two. I does not crash.

I have read some similar issues where Antivirus Software was to blame. I uninstalled Avast Antivirus Software and right now I am only running Windows Defender. In Windows Defender I added exclusions for the installation folder and the profiles folder.

I also added a permission in the Windows Firewall.

In Thunderbird Safe Mode the problem still appears so I guess it's not a problem with Addons.

In Windows 10 Safe Mode the problem didn't appear for sending 10 mails in a row which I can't do right now in normal mode.

I also tried to unistall and reinstall Thunderbird.

This also happens with a new profile via "thunderbird.exe -p".

What could cause the problem here? Any more ideas? I am out of ideas right now.

I think I already find the culprit here: https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems which led me here: http://forums.mozillazine.org/viewtopic.php?p=13750937#p13750937

Since I disabled the windows service "Windows Search", it seems to work like a charme.

Since I had already disabled the setting "Allow Windows Search to search messages" (in Tools, Options, Advanced, General) I am not sure why this should work now or why this setting didn't have any effect.
