Free/busy Exchange hybrid troubleshooting with Microsoft Edge

24th of February, 2017 / / 1 Comment

Those of you who have configured Exchange hybrid with Office 365 before know that free/busy functionality can be troublesome at times and not work correctly.
Instead of searching through Exchange logs I found that you can pin point the exact error message through Microsoft Edge to assist with troubleshooting.
To do so;

  1. Open Microsoft Edge and login to Office 365 OWA (https://outlook.office365.com/owa) with an Office 365 account
  2. Create a new meeting request
  3. Press F12 to launch developer tools
  4. Conduct a free/busy lookup on a person with a mailbox on-premises
  5. Select the Network tab
  6. Select the entry with “GetUserAvailability”devtools-getuseravailability
  7. Select the body tab (on the right hand side)
  8. The MessageText element will display the exact error messagedevtools-messagetext
