I currently use OUTLOOK as an email application, but for the last few weeks when I sent several emails with a copy, Outlook stopped for 3 minutes and then sent the emails. Now when I use Thunderbird and do the same thing, the application does not stop. Now when I uninstalled the antivirus, the OUTLOOK application stopped again, but I reinstalled it and it stopped again.

Disabling the "Add recipient addresses from outgoing messages" setting should work around the issue as suggested at https://forum.eset.com/topic/41730-problem-with-eset-endpoint-security-11120392-and-outlook-2019.
