Get email signature saved to an Outlook account via API

Hi there,

I am using the Microsoft Graph Mail API to send emails from our custom CRM via an Outlook account that our user has added. We want to fetch the email signature saved in outlook by the user and allow them to include this in the emails sent via our custom CRM using the Microsoft Graph Mail API.

I was not able to find any reference to email signatures here: https://learn.microsoft.com/en-us/graph/api/user-get-mailboxsettings?view=graph-rest-1.0&tabs=http

I also found an article that outlined that this is not currently possible: https://learn.microsoft.com/en-us/answers/questions/1093518/user-email-signature-management-via-graph-api

Can you please confirm if such a feature exists?

    Hi @Safia

    This question has been around for a while. As of now, we still cannot manage email signatures using the Graph API, because email signatures are stored by the Outlook client, not in the mailbox. By calling the mailboxSettings API, only mailbox-level objects can be obtained, but email signatures are not included.

    I suggest you submit a user voice on this or vote for the request form.

    Hope this helps.

    I really don't understand why Microsoft don't save these signature in the cloud then users could use it on their office 365 account on the web. And developper could easily retrieve users signatures in apps. This is a hudge lack in graphAPI.
