Troubleshooting errors in SharePoint Online (PowerShell mode)

Troubleshooting errors in SharePoint Online (PowerShell mode)


Ensure that you have met all the prerequisites for the Microsoft 365 monitor.

From Applications Manager version 16300 onwards, Microsoft 365 monitor will use Microsoft Graph API as the primary mode of data collection.
We have migrated from PowerShell to Graph API as Microsoft 365 PowerShell commands were taking more time to execute for huge resources and needed Administrative user privileges to execute the commands. Microsoft provides only archived data in the Graph API. To monitor live data, use the PowerShell mode considering the user privileges and the time taken to fetch huge resources.
For REST API related common errors in Applications Manager from version 16310, refer this KB.
