In some situations you may encounter the following error message in Easy365Manager:
This means that you started and canceled the Office 365 authentication process.
You must complete the Office 365 authentication process in order to manage Office 365 resources like users, licenses and mailboxes using Easy365Manager.
The authentication is performed securely using the Microsoft Modern Authentication API and following Microsoft best practices. Easy365Manager will not know your Office 365 admin password.
If you’re running Easy365Manager version 1.5 or later as a non-Global-Admin you need to set up an Admin Consent on Microsoft Graph PowerShell in order to delegate access.
View this article on how to configure Admin Consent on Microsoft Graph PowerShell.
Refer to the Easy365Manager documentation for further information.
