Run the PowerShell script mentioned in the Microsoft article on the Orion server, not the target node.
- An Orion account with SAM administrator permissions.
- An all-in-one, inclusive Office 365 account with Global Administrator privileges to support the monitoring of all mailboxes.
Alternatively, use an account with an admin role that has permission to access data to be monitored via the Office 365 API.
Use UPN format (
username@domain) — not
domain\username format to enter credentials.
To avoid authentication issues if passwords change, use a service account for Exchange Web Services.
