Access and assign permissions to the Signatures app
Once you're finished registering your Microsoft 365 tenant to CodeTwo you can start working on your email signatures.
You can access the Signatures app (signature management app) at app.codetwo.com (or click Signatures in CodeTwo Admin Panel). The app allows you to create and manage email signature and autoresponder rules from any device and platform (Windows, Mac, mobile devices, etc.).
On first launch, you need to sign in to your Microsoft 365 account and accept the required permissions. Only authorized users can manage signatures and automatic replies (out of office messages) in your organization. Learn more below
By default, email signatures and automatic replies can be managed by all of your tenant's Microsoft 365 global admins. You can also grant access to the Signatures app to other users in your organization. To do so, sign in to CodeTwo Admin Panel, select your Microsoft 365 tenant on the Tenants page, and go to Signature rule admins (Fig. 2.).
To manage signature rule admins, you need to be the owner or an admin in CodeTwo Admin Panel. Learn more
You can add individual users and groups (Microsoft 365 groups, distribution lists, security groups and mail-enabled security groups) by clicking Add > User or Add > Group, respectively.
Your users/groups don't need to be assigned any licenses in Microsoft 365 to become signature rule admins in CodeTwo Admin Panel.
To remove a user/group from the signature rule admins list, click Remove () next to them.
By default, the list contains all your organization's global administrators. Global admins cannot be removed to avoid situations where no user can access and manage rules.
If a user/group is added to the list, this user / all members of this group can sign in to app.codetwo.com and manage all email signature and autoresponder rules.
If you select a group that has other groups nested inside, the members of both the top-level group as well as all nested groups will be granted permissions to manage email signatures.
If you plan to assign rule management tasks to non-admin users, make sure the app registration options in the Microsoft Entra admin center or the User consent to apps option in the Microsoft 365 admin center are temporarily set to the defaults, as described in this article.
Inviting guest users to become signature rule admins
Guest users added to your Microsoft 365 organization can become signature rule admins if they are a member of a different Microsoft 365 organization.
