I'm working with a client that is in process of updating their end users from Office 2010 to Office 2016 and Exchange 2010 to Exchange Online (O365). The issue is that the client endpoints are being updated before the server side.
Apparently, there was an update in Exchange 2013 that enabled a new "Show As" capability as "Working Elsewhere". This however is not supported in Outlook 2010 and is wreaking havoc in the environment when someone sends out a calendar
status set to "Working Elsewhere".
Is there a way through GPO or some type of compatibility setting that we can set to disable this in 2013/2016 clients to ensure that this compatibility isn't an issue? Or is there an update for 2010 that will support this?
Thanks in advance.
