Where are the users’ mailboxes located?

Many of the deployment requirements for Exchange and Lync integration depend on where the user’s mailbox is located.

The following articles cover deployment requirements. These include DNS configuration, Exchange Server configuration, and Lync Server configuration.

Is the user part of an on-premises Exchange Server organization, or are they in Office 365 Exchange Online? 
  • If the user’s mailbox is located in Exchange Online, see the following Knowledge Base article:
    2614242  How to integrate Exchange Server 2013 with Lync Server 2013, Skype for Business Online, or a Lync Server 2013 hybrid deployment
  • If the user’s mailbox is homed on an on-premises Exchange server, see the following Microsoft Knowledge Base article:

MORE INFORMATION

These issues occur when Lync can't determine the user’s email address, can't locate the user’s Exchange server, or can't connect to the user’s Exchange server.

When the Lync client tries to discover the Exchange server of the Skype for Business Online user, the Lync client references the Active Directory WindowsEmailAddress attribute (or the MAIL attribute). Lync then tries to connect to the Exchange server through the Autodiscover process by using the domain suffix of the email address in the WindowsEmailAddress AD attribute. If the Skype for Business Online user doesn’t have an Exchange Online mailbox, or if the necessary attributes aren’t being synced from on-premises, Exchange integration with Lync fails.

After Lync determines where it should look for the Exchange server, it uses Autodiscover to find the user’s mailbox server and connect to it. If the Autodiscover service on whichever Exchange server the user’s mailbox resides is unavailable, the integration between Exchange and Lync fails.

As soon as Lync has the correct mailbox server to connect to, it tries to authenticate by using the Skype for Business Online user credentials first. If those credentials fail, Lync prompts for credentials after you sign in. If the wrong credentials are entered, or the user clicks cancel, the integration between Exchange and Lync fails.
