5. Set it to Disabled.
6. Apply the GPO.
   
   

This will disable signatures for all users in that group.

Using Exchange Admin Center:

1. Log in to the Microsoft 365 admin center.
2. Go to Exchange Admin Center.
3. Under mail flow, create a new rule to remove signatures or disclaimers.
4. This method is more advanced but gives full control.
   

Common Issues and Troubleshooting

Even after following the steps, you might still have some common issues. Here’s how to fix them:

Signature Still Appears After Removal

• Double-check that you saved the changes.
• Look for multiple email accounts: you may have removed the signature for one, but not another.
• Restart Outlook.

Sync Issues Between Devices

If you use Outlook on multiple devices, and the signature keeps coming back:

1. Ensure you’ve removed or disabled the signature on each device (desktop, mobile, web).
2. Signatures don’t always sync automatically unless managed through Microsoft 365 central admin tools.
   
   

Admin Settings Blocking Changes

If you can’t edit or remove your signature:

• Your admin may have applied a GPO or Exchange rule.
• Contact your IT administrator for help.
• They might have used a script or group policy to set or lock down email signatures.
