Hi friends, I am experiencing a serious problem on Outlook in Windows 11 PC. When I open Outlook, I came across this unknown error message "Outlook Error code 0x80040900." I dont know what could be the issue. Why I am getting this unknown error? Could anyone please help me to fix it? Any kind of help would be highly appreciated.

After not getting any response, I started searching about this issue on Google and came across this guide. The main issue was happening due to enable the antivirus. After disabling Kaspersky on my PC, I tried to open Outlook and I it was simply opened. Anyway the problem got got resolved, thats it.
