The first step in installing the Collaboration Manager 365 is creating an administrator account in your Office 365 tenant. You need the adminstrator account to secure the Collaboration Manager 365 is working properly.
Please use this account for installing the app and to configure the settings in your tenant.
Navigate to the administration website of your tenant.
Select "Add users" in the User management tile.
(optional) If you don't have the User Management tile available you can also click on Active Users under Users in the left navigation panel.
(optional) In the active users overview you then click on "Add a user".
Choose the account name. We recommend the same settings as in our screenshot.
Please check sure the username ends with ".onmicrosoft.com".
Choose a password and please make sure that the account does not have to change the password after the first login.
Under "Roles" select "Customized Administrator" and click the checkbox at "SharePoint Administrator" and at "Teams Service Administrator". We need these permissions to improve provisioning.
Check if the "Role" is "Customized Administrator" and then click on the "Add"-button.
The administrator account is now successfully created.
