Prevent your emails from being caught in Microsoft 365 quarantine

What is the best way to stop messages from being quarantined?

I have whitelisted domains but it still happens.

Should I use mail flow rules?

Generally, yes. Create a transport rule to allow these. Rules are better than safelisting domains in the anti-spam policy
