No server needed, you will use Lync as 'Software as a Service'. Much like you can use mail without having Exchange server, etc.

We already have an exchange server and our own domain controller. Can I still use it independent of those two other aspects mentioned?

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.

Office Productivity refers both to the act of being productive and efficient in an office or professional environment, as well as the software applications used to "produce" information. This includes the development of professional skills, creating work processes, and almost any program used to create or modify a document, image, audio or video clip. However, business application suites such as Microsoft Office, which include word processing, spreadsheet and presentation programs, are typically called productivity software, as contrasted with a "utility program," such as a file manager, which is used to organize files and folders on the computer. Many office- and business-oriented groups of programs are organized into suites.
