Can receive, but cannot send email from a connected hotmail account after win11 upgrade

I want to update this thread in case if somebody rans into a similar problem. I created a new profile with my Hotmail account as the default. Then I added my work account to it. So far, I didn't see any errors when sending email from either account. However, the conditional formatting I have used in my other profile doesn't work (has no affect). I am not sure it is related though. I am following up with support on that specific issue separately.
