Hello Eddy**,**
Good day! Thank you for reaching out to Microsoft community.
As per your description and my understanding, you would like to centralize the email signatures across all devices (mobile, computers, laptops, desktops) for the Outlook accounts in your company.
However, you do not have system-level access to manage signature centralization through Azure since this is controlled by your parent company. You are seeking an alternative solution that would allow you to manage the creation of a unified signature for all devices from a single platform or portal. [correct me if I am wrong].
Since you don't have system-level access via Azure to manage centralized email signatures, you can explore third-party tools that provide centralized management of email signatures for all devices, including desktops, laptops, and mobile devices.
- Exclaimer.
- Exclaimer is a widely used solution for managing email signatures centrally. It integrates with Microsoft 365 and Exchange, allowing you to create and manage email signatures for all employees from one place.
- Full compatibility with Microsoft 365 and Exchange
To better understand your issue, I need some addition information so that we can narrow down the main reason and find out the root cause by working together.
- May I know your affected account type and subscription/ license details?
- Is it Microsoft365 business, basic, standard, enterprise (E3/E5), educational or Microsoft Personal account (outlook.com/Hotmail.com/live.com) or any third-party account?
- Which one does it connect to outlook.office.com or https://outlook.live.com/?
- Which outlook platform are you using, is it New Outlook, Legacy (Classic) Outlook or OWA?
- Could you please provide us product and version details of your Outlook?
- Are there any third-party tools or signature management services your parent company has approved or considered in the past that you can leverage?
- Do you require different signatures for internal and external emails, or would the same signature apply in all contexts?
- Is there any existing system in place for managing other centralized configurations that you may be able to integrate signature management with (e.g., Office 365 Admin Center, or a third-party MDM solution)?
Please understand that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.
Thanks for choosing the MS community.
Looking forward to your response and have a great day ahead!!
