Consider the following scenario:
Note This issue does not occur if an Office 365 user uses Microsoft Outlook 2010 to look up an on-premises user’s free/busy data.
This issue occurs because Outlook 2013 defines a new Working Elsewhere free/busy value for calendar items. When Office 365 users request free/busy data, the on-premises Exchange 2010 server incorrectly maps the new free/busy value.
To resolve this issue, install the following update rollup:
(https://support.microsoft.com/kb/2891587/ )Description of Update Rollup 3 for Exchange Server 2010 Service Pack 3
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
