How to manage a Microsoft 365 tenant without a CodeTwo Admin Panel account

If you purchased the software from one of our distributors (resellers) and you do not have your own CodeTwo Admin Panel account, you can still manage tenant-related settings as long as you are a global admin of your tenant. To access these settings, go to app.codetwo.com, log in using global admin credentials, click the ESIG for O365 More button button in the upper-right corner of the window, and then click Settings (Admin Panel), as shown in Fig. 3.

A simplified version of the Admin Panel opens in your default web browser (Fig. 4.). It gives you access to tenant management options: you can reconfigure connectors, specify which users are allowed to manage email signatures, enable/disable SIU, synchronize additional attributes, deregister your tenant from CodeTwo Admin Panel, etc. The only exception is the Subscription page: you are not able to modify your subscription in any way. Subscription options can be managed only by the person who owns the CodeTwo Admin Panel account (e.g. your reseller). The account under which your tenant is registered in the CodeTwo Admin Panel is shown next to Registered under (see Fig. 4. below).

Users who are not global admins but have permissions to manage signatures in your organization cannot access the Manage tenant pages in the way shown earlier. If they try to go to the Admin Panel settings as shown in Fig. 3., they will land on the CodeTwo Admin Panel login page (Fig. 5.).
