Resource processing To allow target users access source SharePoint, linked guest users were created in the source and On Demand Migration immediately attempts to grant these user accounts necessary direct permissions. It can take time for guest accounts to replicate to SharePoint, which can result in a "User not found" error message for a guest account that has not yet been replicated during granting permissions. Workaround: Retry the SharePoint processing later. |
