Before starting the setup, make sure you have the following:
-
An Azure Active Directory subscription
An Azure Active Directory subscription is required for Exclaimer Cloud to connect to and synchronize data from. Azure Active Directory subscriptions are automatically provided with most Microsoft 365 plans; however, you can sign up for free if you do not have an Azure Active Directory subscription. See How to configure and synchronize Azure AD for use with Exchange On-Premises.
-
Azure Active Directory Connect configured and synchronizing
To ensure all the user data is automatically synchronized between the on-premise and Azure Active Directories, it is necessary to have Azure Active Directory Connect configured and synchronizing. See how you can set up Azure AD Connect to use the tenant.
-
Credentials for a Global Administrator account within the Azure Active Directory subscription
During the setup, you will be prompted to sign in with an account to authenticate various Azure apps. The level of permissions required for the account used during setup is given by the Global Administrator admin role.
If the account is configured to require multi-factor authentication, then this may also be required during the setup process.
