    7. We need to now disable Lync Online for E4 users. If all users in the company need phone lines, we can disable Lync Online for everyone (refer 7b to disable companywide). If only selected users require Enterprise voice, then disable Enterprise for them as follows.
      • Login to Office365 control panel, Click ‘Users’, select required user and ‘Uncheck’ Lync Online.
        You can also check list of Office 365 Lync Online users on the ‘Lync Online Control Panel’. If you are enabling Lync Enterprise Voice for all users then this list should be empty.
      • If you want to disable Lync Online for everyone in the company, then follow these steps
        Under Office 365 Admin Center, Domains, click ‘Active’ next to your customized domain.
        Then click ‘Change Domain Purpose’ and ‘uncheck’ Lync Online.
        Now we have disabled Lync Online, let us enable ‘Unified Messaging’ on Office 365.
    8. Sign onto portal, in the top ribbon menu, Select Admin and Exchange
    9. Select ‘Unified Messaging’ and click + to create a new ’UM Dial Plan’. Give a name to the UM Dial plan and enter values for other fields as follows. Enter your appropriate Country Code and Click Save.
    10. Under ‘Recipients’, Mailboxes, Select a User and double click on the selected user to get into details. Scroll down and click ‘Mailbox Features’, click Unified Messaging and enable it.
    11. For UM mailbox policy, click ‘Browse’ and select policy just created and click ‘Save’.
    12. Next enable Unified Messaging for all Users using the same steps.

This completes Exchange Online and Unified Messaging integration with VOIP Connections Hosted Lync.

Next step is validation.

  1. Login onto Office 365 email portal, select Outlook from top ribbon menu, click People, Contacts and you will immediately notice ‘Status’ of contacts.
  2. When someone leaves a voice mail on Lync, it will appear as email and transcribed by Unified Messaging.
