The remote server returned an error:(401) Unauthorized
説明
At times there are 401 and 403 errors returned from SharePoint Online during a migration. The errors were never seen while testing a connection from Migrator for Notes to SharePoint (MNSP). The errors were only present when migrating data to SharePoint Online.
原因
There are multiple migration hosts which are performing migrations using the same account to connect to SharePoint Online.
対策
Each migration host should have a separate SharePoint Online admin account for connecting to SharePoint Online.
Not having a separate account and running multiple migrations from MNSP hosts could result in migrations getting throttled.
