How to disable the Outlook roaming signatures feature
You want to disable the Outlook roaming signatures feature released by Microsoft because your old signatures are being synchronized from Outlook for Windows and Outlook on the web (OWA) and mixed up with signatures added by CodeTwo Email Signatures 365.
Use the links below to learn how to:
- Disable roaming signatures by using PowerShell (works only for Outlook on the web and new Outlook for Windows)
- Disable roaming signatures globally via GPO (works only for classic Outlook for Windows – instructions for IT admins)
- Disable roaming signatures individually (locally) for a user (works only for classic Outlook for Windows)
Microsoft is in the process of rolling out the -PostponeRoamingSignaturesUntilLater parameter used in the steps below. The roll out is expected to be completed by mid-November 2023. If the solution doesn't work for your Microsoft tenant, you can either try again later or open a support ticket with Microsoft and ask them to have Outlook roaming signatures disabled in your organization.
- Connect remotely to your Microsoft 365 tenant with PowerShell, as described in this article.
- Run the following cmdlet
Set-OrganizationConfig -PostponeRoamingSignaturesUntilLater $true
- Disconnect from your tenant using:
- Sign in to your domain controller.
- Run the Group Policy Management Console as an admin (type gpmc.msc in the Start menu).
- Right-click the relevant organizational unit (OU) and choose Create a GPO in this domain, and Link it here (Fig. 1.).
- In the New GPO window that opens, name your policy object (e.g. DisableRoamingSignatures) and click OK (Fig. 2.).
- Right-click your newly-created GPO and select Edit (Fig. 3.).
- When the Group Policy Management Editor opens, go to User Configuration > Preferences > Windows Settings > Registry in the left-hand navigation pane. Next, right-click Registry and select New > Registry Item (Fig. 4.).
- Configure the settings for the new registry item as shown in Fig. 5.:
- Action: Update
- Hive: HKEY_CURRENT_USER
- Key Path: Software\Microsoft\Office\16.0\Outlook\Setup\
- Value Name: DisableRoamingSignaturesTemporaryToggle
- Value Type: REG_DWORD
- Value Data: 1
If you’re using Outlook 2013 SP1 in your organization, replace 16.0 with 15.0 in the Key Path value.
If you’re using both Outlook 2013 SP1 and newer Outlook versions in your organization, you might be required to create two identical registry items that differ only in terms of the Key Path value, as highlighted in the previous paragraph.
- Click Apply and OK to apply your changes and close the configuration window.
Once the GPO propagates, the Outlook roaming signatures feature will be disabled for your users.
There are two ways to disable roaming signatures in Outlook for Windows on a local computer:
- Download and run a REG file to quickly update Windows registry
- Manually add the key that disables roaming signatures to Windows registry
You can download the REG file linked below and then execute it to quickly add a Windows registry key that disables the roaming signatures feature in Outlook for Windows on your computer. If you prefer to modify Windows registry manually on your own, have a look at this section instead.
- Download the zipped REG file from here.
- Unzip the file.
- Double-click the file to run it - you need to have administrative privileges on the computer where you want to update Windows registry.
- Click Yes to close the warning message and add the key that disables the roaming signatures feature. Once Windows registry gets updated, a relevant message will be displayed.
- Launch or restart Outlook for Windows for the change to take effect.
- Run the Registry Editor (RegEdit) with administrative privileges.
- Copy the following path:
Paste it into the Registry Editor’s address bar, as shown in Fig. 6., and press Enter to navigate to that path.
If you’re using Outlook 2013 SP1 to connect to Microsoft 365 (Office 365), the path won’t work. To fix it, replace 16.0 with 15.0.
- Right-click anywhere inside the right pane and select New > DWORD (32-bit) Value (Fig. 7.).
- Name the value DisableRoamingSignaturesTemporaryToggle and press Enter.
- Next, double-click the value. In the Edit DWORD (32-bit) Value window that opens, enter 1 in the Value data field and click OK (Fig. 8.).
- Close the Registry Editor and restart Outlook for Windows for the changes to take effect.
