Keep familiar tools. Make records responsibilities clearer.
SharePoint supports shared sites and document libraries. Teams brings conversations and teamwork together, with channel files stored in SharePoint. OneDrive supports individual files and sharing, including files shared in Teams chats.
OpenText Content Manager is an electronic document and records management system. It helps organisations manage information with classification, metadata, access controls, retention and disposal processes.
