Hi everyone
I'm not sure what I'm overlooking here, I keep getting the error message below even though the configurations appear to be correct. Could someone help suggesting what I might be missing based on the error code?
Event Viewer ERROR - "The user principal authorized for background operations does not have site administrator rights, so 'Site Collection Administrators' group is skipped during synchronization. This could result to limited access for some users. To fix this we recommend to configure SharePoint app-only principal for indexer user."
FYI - I am the Owner of the SharePoint Sites - Full Control
