Missing out on important emails? Check out this guide on how to personalize email settings so you can remove emails from quarantine in Office 365 with ease.


Missing a critical client email to solidify a deal can be almost as devastating as an employee being duped by a malicious email. While it can be liberating to have emails filtered out automatically for you, it’s not uncommon for the filter to accidentally quarantine an email that you would deem important. And, in 365 Defender, the feature to enable users to request the release of an email from quarantine is not enabled by default.  

While we want to be able to empower users to search for legitimate emails in Microsoft Defender’s quarantine, we also want them to be able to expedite their ability to remove emails from quarantine in Office 365. The following steps detail how 365 users can ensure they don’t miss any essential emails. 

An Important Reminder 

First off, having a visual cue to periodically check the quarantine can give vigilant users an extra step in security. 

We highly recommend that our clients place the shortcut URL on their desktop (see below) so that they don’t miss any legitimate emails.
