How to control if you have quarantined emails

You can access your quarantine page at any time from the web page Microsoft 365 Defender / Quarantine 

If you are waiting for a specific email that has been quarantined, please contact ServiceLine.

How your quarantine page looks

Your personal quarantine web page lists all the messages that have been withheld over the past 30 days (even after you have released them to your inbox).

The page will list your quarantined emails with the following information:

• Date and time of receptions
• Subject
• Sender
• Quarantine reason
• Release status Policy type
• Expiring date
• Recipient

Due to the last Microsoft changes and to cyber security reasons, the following buttons have been disabled:

• Release
• Request release
• Delete messages
• Preview messages

If you need a message to be released, please contact ServiceLine. Our technicians will investigate and let you know whether the message contains dangerous links or files attached or if it comes from a reliable source.
