Microsoft will be deprecating Application Impersonation for Exchange Online this February 2025
Please set up OAuth for your CloudAlly backups. Your backup will cease if Authentication is not reset. This is because Microsoft will be deprecating Application Impersonation for Exchange Online in February 2025.
In 2022, we removed our dependency on Microsoft's Application Impersonation due to the impending deprecation. Please follow the very simple steps below to re-authenticate your backup tasks to ensure the health of your backups with CloudAlly.
Steps to authorize CloudAlly Exchange Online backups using OAuth
1. Log in to your account.
2. Click on the Office 365 Exchange backup task.
3. Click the "Connected" or "Disconnected" icon.
4. Select "Use OAuth-based authorization."
5. Click the "Authenticate" button.
6. Login to your Microsoft backup services account to complete the authentication.
Please consider this urgent: Any Exchange backup still using Application Impersonation will no longer work once Microsoft deprecates the service.
