No email filtering system is perfect and it's inevitable that the occasional message will end up in your spam or junk folder.

If you use Outlook for work, they may even get put into ‘quarantine’ and unless you know where to look and find those emails, you might think they never arrived at all. Note that quarantine applies only to organisations using Microsoft 365 with mailboxes in Exchange Online or standalone Exchange Online Protection (EOP), not personal Outlook accounts.

Here, we'll show you how to check for quarantined emails, release them from the quarantine folder and mark them as ‘not junk’ to avoid it happening again.

This procedure is the same for desktop and iOS and Android web browsers.
