If you want to prevent users from adding signatures in Outlook, here is how you can do that. It is possible to enable this setting with the help of the Registry Editor and the Local Group Policy Editor. After turning it on, Outlook won’t display the option to add the signature that you created earlier.
Let’s assume that you are in a team, and you do not want to include any signature in any email sent on behalf of your company. There are two options. First, you can remove the signature manually. Second, you can use this method to get the job done. These guides below are fruitful when you have multiple customized signatures, and you do not want to remove them.
How to prevent users from adding signature in Outlook
To prevent users from adding signature in Outlook using Registry, follow these steps:
- Press Win+R to display the Run prompt.
- Type regedit and hit the Enter button.
- Click the Yes button.
- Navigate to office in HKCU.
- Right-click on office > New > Keyand name it as 0.
- Repeat these steps to create another sub-key named common.
- Right-click on common > New > Keyand name it as mailsettigns.
- Right-click on mailsettings > New > DWORD (32-bit) Value.
- Set the name as disablesignatures.
- Double-click on it to set the Value data as 1.
- Click the OK button and restart your computer.
Let’s check out more about these steps.
To get started, press Win+R to open the Run prompt, type regedit, press the Enter button, and click on the Yes option on the UAC prompt to open the Registry Editor on your PC.
Then, navigate to the following path:
HKEY_CURRENT_USER\Software\Policies\Microsoft\office
Right-click on the office key, select New > Key and name it as 16.0. Then, right-click on the 16.0 key, select New > Key from the context menu, and set the name as common.
After that, you need to create a sub-key under the common key. For that, right-click on common > New > Key, and name it as mailsettings.
Once done, create a REG_DOWRD value. T do that, right-click on mailsettings > New > DWORD (32-bit) Value and call it disablesignatures.
Double-click on this REG_DOWRD value to set the Value data as 1.
Then, click the OK button and restart your computer to get the change.
If you want to allow Outlook to add signatures to e-mail messages, you have two options. You can set the Value data as 0 or delete the REG_DWORD value. If you want to delete the REG_DWORD value, right-click on it, select the Delete option, and click on the Yes button.
The same thing can be done with the help of the Local Group Policy Editor. However, you need to install the administrative template for Office first.
