I am noticing in my Office 365 tenant that there are numerous "failed login attempts" on almost all the users in the company?  Why does this typically happen and what should I do to protect the company?  I'm wondering if its a bot trying to attempt a hack.

FYI, the main admin account is MFA so that is secure.  Should I consider putting a limit on attempts to login?  If so, how do I do that and will that prevent users from logging that currently have access?
