Outlook 365 won't receive email? Help please.

I just updated my Bitdefender on Saturday along with my annual renewal on both my desktop and my laptop. As of this morning, I can send emails from my work account through Outlook 365 but I cannot receive emails in my work account (Gmail and other accounts have not been effected). This happened on BOTH my laptop (Win11) and Desktop (WIN10). My android phone which has Outlook, and was running Bitdefender but not updated was not effected. Has this happened to anyone else? Is there a solution?

I have reset all my account settings, restarted, etc. No luck
