Lync is Microsoft’s messaging client for corporate use. It uses the OSU global address book to connect all employees together allowing for faster collaboration. Only users with a Microsoft Exchange? account (firstname.lastname@example.org) may use OSU's Lync service. You may also use Lync to communicate with persons who do not use Lync.
If you are unsure whether your account is capable, please contact your IT support group for clarification.
