All SharePoint sites have an "Owner" that is a member of the department the site relates to. This allows each department to be self-sufficient about assigning permissions and creating new content.
The administration resources are intended to guide site owners through the most common functions (creating new sites and assigning permissions). However, if you have any issues with your SharePoint site, contact the OIT Support Center.
Who is the Owner of My SharePoint site?
The "Owner" of your department SharePoint site is the department admin assistant. If it isn't them, they will usually know who it is. However, if that is not the case, please contact the OIT Support Center to retrieve that information.
