The On-premise Exchange can be integrated with the Lync Online through this method. In fact it is not an integration but a method to achieve it. You just have to install Directory sync tool and sync all the users from your on-premise to the cloud. After that, choose the users in Office 365 and enable the lync online license for them. Thats it. Now install the lync client on the pc/laptop and the integration will work when meeting all of the following criteria.

Criteria are as follows:

• Outlook client should be at least Outlook 2007 SP2 with latest hotfix applied
• Available Lync Online service license is assigned & do not assign Exchange Online service license to these object created in Office365 MOP
• SIP address for your Lync Online should be identical to your On-Premise primary SMTP address
• The On-Premise Exchange account should be configured to the same PC where you sign in Lync client for the same account

After that, Lync client will show the presence integrated with Outlook client and the conversation history will be saved to your On-Premise Exchange mailbox. The working principle explanation is at http://technet.microsoft.com/en-us/library/gg398806.aspx Outlook 2007 makes RPC calls to resolve SIP addresses only if the Display online status next to a person name option is selected. To view this option in Outlook 2007, on the Tools menu, click Options, click Other, and then look under Person Names

In Outlook 2010, on the File ab, click Options, click Contacts, and then look under Online status and photographs

In addition, the Lync Online Presence with Outlook client only works for the account for whom configured the type as Exchange Protocol or (Outlook Anywhere). (IMAP/POP/SMTP type is not supported the feature)
