Clear a sender so that messages are not quarantined

[silsbeel]

I have an external contact on a project and when he sends messages they are
quarantined. I've clicked on the wrong link in the quarantine notification
to clear the user and instead have just released the messages. How can I
otherwise verify this source?

Outlook has no quarantining function. Go read the manual regarding your
anti-virus software (or whatever is interrogating your e-mail traffic)
to determine how to configure it.
