You can remove or hide the “Report Message” / “Report Phishing” button in Outlook using several methods, depending on whether you’re using Outlook for Microsoft 365 (desktop), Outlook on the web, or via Exchange/Intune policies.
1. Using Outlook Desktop (Microsoft 365 / Office 365)
Method A: Remove from Ribbon via Customize Ribbon
·
Open Outlook.
·
Go to File → Options → Customize Ribbon.
·
In the right panel, select the tab containing
the Report Message / Report Phishing button (usually Home → Message).
·
Click Report Message and select Remove.
·
Click OK to save changes.
⚠️ This only hides it from your
current Outlook profile.
Method B: Remove via Add-in Management
The Report Message button is often part of the Report
Message / Report Phishing add-in.
·
Go to File → Options → Add-ins.
·
At the bottom, in Manage COM Add-ins, click Go….
·
Locate Microsoft Report Message Add-in or Report
Phishing.
·
Uncheck it to disable, or select it and click
Remove.
·
Restart Outlook.
This method disables the button completely.
2. Using Outlook on the Web (OWA / Exchange Online)
·
Log in to Outlook Web.
·
Go to Settings (gear icon) → View all Outlook
settings → Mail → Customize Actions.
·
Look for Report Message / Phishing toggle.
·
Uncheck to remove it from the message toolbar.
3. Using Exchange Admin / Intune Policies (Enterprise)
·
Exchange Online allows admins to disable the
Report Message add-in organization-wide.
·
Steps for admins:
·
Connect to Exchange Online PowerShell.
·
Run the following command to disable for all
users:
·
Disable-App -Identity "Report Message"
-Organization
·
Alternatively, configure Intune or MDM policies
to prevent installation of this add-in.
·
Recommended for enterprises to maintain
consistent experience across users.
Removing the button does not prevent users from reporting
phishing manually via email to security teams.
If you are not an admin, the easiest is Method A or B.
If you want to disable it for all users, use Exchange
Online/Intune policies.
