Hi,

As per the information and details provided by you, to solve the issue of free busy, please follow these steps: -

The main reason is KB2837643 and KB2837618, I found that both updates must be uninstalled, if you have a one or the other installed, you will have intermittent access to those resources, and if you have both installed, it wont work at all. In additions both updates cause a profile corruption, requiring the Microsoft Outlook 2013 profile to be recreated.

I hope this information will be helpful for you.

Thanks and regards

Hi Steve,

We're not trying to open a users calendar but trying to look at free busy data for scheduling. When the user logs onto OWA, they add an individual, free busy scheduling is not displaying. My outlook 2013 is joined to the domain, and my free busy is working. When I logon to OWA, add a user to a calendar invite, free busy is not displaying in OWA. I verified all the exchange 2007 web services and don't see any issues.

Here's scenario:

User 1 - Outlook 2013 workstation not joined to domain, free busy in outlook 2013 not displaying (receives no connection), OWA free busy not displaying, verified patches KB2837643 and KB2837618 not installed. This is a replacement PC but previous setup with same settings worked.

User 2 (Me) - Outlook 2013 workstation joined to domain, free busy in outlook 2013 is working and displaying schedules. OWA free busy not displaying. Patches KB2837643 and KB2837618 not installed,

Hi Goyal,

I verified Patches KB2837643 and KB2837618 are not installed on end user machine.

Thanks,

Kenny

Thank you for the update, Kenny. I found the following article which explained "Issues With Accessing Free/Busy Data From a Non-Domain Workstation" in detail, please have a look at it and check if it applies:

"The problem is rooted in how the client software goes about determining where to find the Availability Service.  The Availability Service is web-based, and the client needs to know what URL to connect to in order to swap the relevant SOAP/XML requests. To find this, the client must first determine the SOAP/XML URL for the AutoDiscover service.  Once that is found, the AutoDiscover Service can be queried to determine the Availability Service URL."

Since this forum focus more on Outlook client side question, it's better to post your question to the Exchange forum to get further assistance:
