Veeam for Microsoft 365 Not allowed to access Non IPM folder Error
Microsoft constantly pushes out changes, and sometimes these changes break things for 3rd party vendors. After a recent change, we had started seeing the error message “Failed to get folder properties. Not allowed to access Non IPM folder” across several backups. The Microsoft change to the properties of the TeamsMessagesData folder caused Veeam to be unable to retrieve the data over the EWS APIs. Luckily, the fix for this a quick and easy! Note: This requires you to be on Veeam for Microsoft 365 6.1.0.1015 or Newer. Implementing the change on prior versions will NOT resolve the issue. We recommend upgrading to a supported version before applying the following fix. Recent Veeam for Microsoft 365 releases cover this issue. Please follow these steps: If you continue to experience issues or would like assistance with any other issues you may be experience, please reach out to Support@Managecast.com.
