How do I configure my SharePoint migration projects with the correct SharePoint URL?
When creating a Document Migration project with SharePoint as either the Source or the Destination, the correct SharePoint URL must be provided for input. When the actual migration entries (the Mailboxes) are created, the name of the Document Library must be included.
For example, if the SharePoint site URL is https://tenant.sharepoint.com/ThisIsMySharePointSitePath/ layouts/15/start.aspx# , then use the following portion for the correct URL settings: https://tenant.sharepoint.com/ThisIsMySharePointSitePath
In order to migrate from or to the "Shared Documents" document library, type "Shared Documents" in the Mailbox migration entry.
If you are pulling the name directly from the URL, here is an example of the URL with the "Shared Documents" in it: https://tenant.sharepoint.com/ThisIsMySharePointSiteUrl/_layouts/15/start.aspx#/Shared Documents/Forms/AllItems.aspx
The default site is usually found at https://tenant.sharepoint.com
