To globally turn off the Outlook Roaming Signatures feature using PowerShell and prevent changes to your signature format in OWA, follow these steps:

1. Open a PowerShell window.

install-module ExchangeOnlineManagement

Note: If you haven't installed it yet, please install the ExchangeOnlineManagement PowerShell module. This requires PowerShell 5 or above.

2. Connect to Exchange Online.


3. You can just run the following commands to disable roaming signatures.

Set-OrganizationConfig -PostponeRoamingSignaturesUntilLater $true

Note: $true: Roaming signatures are temporarily disabled for Outlook on the web and the new Outlook for Windows. When roaming signatures are disabled, Admins can use signature-specific parameters like SignatureHtml, AutoAddSignature, AutoAddSignatureOnReply, etc., on the Set-MailboxMessageConfiguration cmdlet to configure email signatures. 
For Windows, the registry setting to disable roaming signatures will continue to work.

If you decide to return the Roaming Signatures feature, for example, to see the signatures list to switch between your signatures in Outlook, you can turn it on by following these steps:

1. In the PowerShell window, connect to Exchange Online.


2. Run the following commands to enable roaming signatures.

Set-OrganizationConfig -PostponeRoamingSignaturesUntilLater $false​

Note: Enabling the Roaming Signatures feature took about 24 hours.

To manually turn off the Outlook roaming signatures feature and prevent changes to your signature format in Classic Desktop Outlook, follow these steps:

1. Launch the RegEdit (Registry Editor).

2. Navigate to:


3. Right-click anywhere on the right panel, select New, then select DWORD (32-bit) Value.

4. Enter the DWORD name as DisableRoamingSignaturesTemporaryToggle and press Enter.

5. To edit the value, you can either right-click the DisableRoamingSignaturesTemporaryToggle and select Modify or double-click DisableRoamingSignaturesTemporaryToggle.

6. In the Edit DWORD (32-bit) Value window, enter the value 1 in the Value data field.

7. Select OK to save the changes and close the window.

8. Restart Outlook so the change takes effect.
