Office Integration Start a collaborative conversation directly from familiar Office applications Share from any conversation Easily transition from talking to sharing work Flexibility to control how you want to collaborate Have confidence that you are in control Simple, Direct Collaboration Add files to conversations Just like e-mail has attachments, so do conversations. Add files to phone calls, IM chats, or conferences Transition from talking to working Easily add your screen, a PowerPoint presentation, or a whiteboard to your conversations Sharing Activity Users are presented with a more visual way of deciding which activity they want to engage in around sharing 6

7. Joining conferences Lightweight conferencing experience confirms that you are in the right meeting and ready to participate Single click scheduling Users are presented with a single button for scheduling common meetings Join in Outlook ribbon Return to the calendar and push the “join online” button to enter the meeting Online meetings are an essential part of your workflow Schedule most common types of meetings with the fewest clicks Bring join to the user, rather than taking the user to join Reinforce that participants are ready and able to participate Keep the experience simple and expand as the meeting expands Easy Online Meetings Meeting invite Clean and clear message body emphasizes joining via Lync 2010 but allows you to also join by phone 7

8. Asynchronous viewing Presenters can navigate other content in the meeting. Helpful for review content before presenting or taking notes on the shared whiteboard Video View meeting participants and meeting content at the same time Meeting management Keep track of meeting participants, access call controls, and view notifications just like you were in a phone call or IM Roster and lobby It’s not just about what is being shared, but also who is seeing it. Roster controls let presenters manage the room, including admitting people from the meeting lobby Lync 2010 lets you set the stage and keeps you in control Join experience inspires confidence and trust Content is king (when present) Presenters are informed and in control Social context is important; know who is “in the room” and who is making changes Professional Online Presentations 8

35. Migration and Coexistence 35

36. Migration and Coexistence Challenges Microsoft Lync Server 2010 changes the impact Interoperability Lync 2010 is the only desktop conferencing Support for Web based conferencing client (Conference join link moving to https:// based (from meet:// and conf:// ) New Conferencing access model Federated user treated as external Tightened role based application sharing New lobby functionality New Web conferencing server not backward compatible New assigned conference with changed simpler conference URL Challenges Existing meeting invite for migrated meetings must still work Migrated meetings must work as before 36

37. Migration and Coexistence Solution – Existing meeting invite for migrated meetings must still work Lync Server 2010 server supports live meeting before Lync Server 2010 client upgrade Design Lync Server 2010 front end server contains a Live Meeting compatible web conferencing server PSTN dial-in inter-pool transfer Admin experience during migration Migrate existing meetings for migrated user (DBImport/export, or MoveUser) Optionally move Live Meeting content using Lync Server 2010 ResKit tools User experience after migration Client not updated All scheduling functions from OCS 2007 R2 Outlook add-in work All conferencing URLs in existing invites work Client updated All conferencing URLs in existing invites work New conferences scheduled generate Lync Server 2010 style invite Modifying existing conference invites convert invites into Lync Server 2010 style and resend 37

38. Migration and Coexistence Solution – Migrated meetings must work as before Lync Server 2010 server support compatibility mode Lync Server 2010 front end server provides compatible behavior for two types of meetings: Migrated meetings Meetings scheduled on Lync Server 2010 server using previous version clients Admin experience during migration No admin action needed User experience after migration Federated users treated as authenticated user Application sharing can be started by anybody in meeting No lobby 38

39. Migration and Coexistence Limitations Migrated user gets new assigned PSTN conference ID Live Meeting content is not moved automatically with meetings Existing CWA 2007 R2 server needs to be kept around Meetings scheduled using Lync 2010 clients on Lync Server 2010 server will not work after user is moved back to a previous version OCS server 39
