The Windows SharePoint Services adapter Web service encountered an access-denied error when moving a file from source document library {0} to destination document library {1}. The BizTalk host instance account requires Contributor-level permissions. To fix this issue, add the BizTalk host instance account {2} to the SharePoint Enabled Hosts group and make this group a member of the Contributors role in SharePoint. The group membership will not take effect until you restart the BizTalk host instance.
