Overview:

It is possible to locate the OAB and EWS URL's which are needed for the Nebula Synchronizer when Microsoft Exchange is your calendar system. Follow this guide to find out how this is done.

How to:

Start/Open Outlook and notice the small Outlook icon in the taskbar / System Tray. If you hold the CTRL key and do a right click on the Outlook icon you will see a menu as the screenshot below shows.



Select "Test E-mail AutoConfiguration", as this will open the test functionality (see screenshot below). Fill out the E-mail Address and password, and click the Test button.



In "Results", you can find the EWS and OAB urls.

  • EWS: also shown as the Availability Service URL or OOF URL
  • OAB: also shown as the OAB URL

If you get an error message, or no link to the OAB is supplied, it could be due to a setting on the Exchange server. Please contact your (local) Exchange Administrator and they will supply you with the correct URL's.
