Outlook signature

Question

Outlook signature

Frédérico Rodrigues 5

Hello,

I'm having a problem with signatures on Outlook. I deploy the signatures via GPO, which works fine because when I open Outlook classic, the signatures appear. But when I migrate Outlook to Outlook new, the signatures disappear. I've tried setting the DisableRoamingSignaturesTemporaryToggle registry key to 1 in HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Setup

it doesn't solve the problem.

I've also noticed that when I create an outlook new signature and return to classic, the signature doesn't appear.

Here's the answer from someone in the Microsoft community

“First of all, regarding the registry change you mentioned, I think you must have come across articles about the Outlook Signature Roaming feature. However, the signature roaming feature is designed to support synchronization of signatures on different devices for the classic version of Outlook only.

Please note that there is no direct iterative relationship between Outlook (classic) and the new Outlook. Outlook (classic) is a C-based application, while the new Outlook is web-based. Its design focuses on providing Windows users with a free, lightweight e-mail client.

Signatures in the classic Outlook are stored locally, while signatures in the new Outlook are stored on the server. There is no direct communication or synchronization between the two. Therefore, I can only suggest that you create separate signatures for classic Outlook and new Outlook.

Thank you for taking the time to answer this question. Feel free to post if you need any further help. I wish you all the best.”

So what I also understand is that by GPO it's impossible to deploy signatures on the new version, right?

And is it possible to deploy a genetic signature on the outlook web in a company?

Thansk for your help

Answer 1

In short - there's no way to use GPO to set up email signatures in the new Outlook. And if you're using VBScript, there are plans to deprecate it soon, so it won't be possible to use it for the classic Outlook either. There are alternatives, though.

You can use PowerShell to add email signatures to users' mailboxes. Set-MailboxMessageConfiguration , to be precise. Here is a walkthrough for the process . Mind it might not work with the "roaming signatures" aka "signature cloud settings" turned on. And, like @SokiGuo-MSFT mentioned, you can use mail flow rules to add disclaimers. The process is even easier if you use a dedicated signature generator, which lets you get HTML code ready to paste into Exchange admin center. This video includes a step-by-step guide.

Those methods are completely free to use, but have some limitations. Other alternatives require third-party signature management tools.

Hi @Frédérico Rodrigues

Welcome to our forum!

Yes, deploying email signatures via Group Policy (GPO) isn’t supported in newer versions of Outlook.

And is it possible to deploy a genetic signature on the outlook web in a company?

Do you want to make all users with same email signature? If so, you can transport rule to add disclaimers as the Organization-wide signatures.
