Tested on Windows 10 2004 with Outlook 2019. PC=core i5 or i7 8 or 16 gb RAM and SSD. Icewarp connector 12.3 slow down the PC. Outlook takes 24% CPU ressources (less than 8% without connector in IMAP account). About 30s after launching on a small account (less than 5Gb PST) to create new message, and wait 5 ou 10s to change directory in the mail. Synchronisation always on : it is so slow that the progressive bar never end.
