Disable Microsoft Outlook Signature syncing

Microsoft Outlook now supports signature syncing across devices which for most is a very useful feature, but if you are sharing an email account and using personal signatures, then this could be an issue for you.

To disable the signature syncing in Microsoft Outlook, firstly try this:

1. In Outlook, select File > Options > General

2. Untick 'Store my Outlook settings in the cloud (requires restarting Outlook)

3. Close and re-open Outlook

If that does not work, then you can try disabling via the Registry and here are a couple of ways to do that.

Use a REG file to Quickly Update Windows Registry

Follow the steps below:

1. Download the zipped REG file from here.
2. Unzip the file.
3. Close Outlook.
4. Double-click the file to run it  (you need to have administrative privileges on the computer where you want to update Windows registry).
5. 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.
6. Launch or restart Outlook for Windows for the change to take effect.
