Give an example of a comprehensive collaboration tool kit

What will be an ideal response?

Microsoft's product Office 365 is a comprehensive collaboration tool kit. Office 365 is provided as a service over the Internet. Lync is a communications application that provides IM, audio and video conferencing, and shared whitespaces as well as shared desktops and shared applications. Furthermore, this set is integrated; SharePoint alerts can send emails via the Microsoft email server Exchange when tasks or other lists and libraries change. One can click on users' names in emails or in SharePoint, and Office 365 will automatically start a Lync text, audio, or video conversation with that user if he or she is currently available. All text messages that you send via Lync are automatically recorded and stored in the individual's email folder.
