I use the online archive function provided by Exchange 2013 (not the 365 online!), and suddenly i get this message via Outlook 2013 when i try to open it:
Cannot expand the folder. The set of folders cannot be opened. Microsoft Exchange is not available.
err.. yes it is 🙂
After a fair amount of searching, i came across this: http://support.microsoft.com/kb/2992644
It requires a restart.. sigh.. but rebellious as I am, i just started outlook anyway. What do you know, its now working again 🙂
Now im off to deploy this via SCCM. Make a package with the /SILENT parameter, and you should be good.
