Autodiscover to external Exchange Server

0

Recently i had to migrate office mail from an on-premise Exchange (2010) server to Office 365. After the “switch over” (and changing DNS settings for mail and auto-discover to the Microsoft servers) i noticed that Outlook (2007) on the on-site PC’s which are member of the local domain, still auto-discovered to the on-premise exchange server. After some digging around i found out that outlook retrieves this information from Active Directory and you can change this via Active Directory Sites and Services.

  • Once opened, navigate to Services -> Microsoft Exchange -> -> Administrative Groups -> -> Servers -> -> Protocols -> Autodiscover.
  • Right click on your server and choose properties.
  • Go to the Tab Attribute Editor
  • Look for the setting serviceBindingInformation and change it to your needs.
  • OK to apply

After this change, Outlook auto-discovered to the correct server.
SCP AD autodiscover aanpassen

Note: If you don’t see Services, click View -> Show Services Node
