I have followed http://technet.microsoft.com/en-us/library/jj150486(v=exchg.150).aspx in migrating our modest PF on Exchange 2007 to Exchange 2013 (we are sitting on a co-existence at the moment).
After step 7 and on Step 8, when I set myown account as test and opened Outlook, I was greeted with the below message when I tried to open our PF from Outlook 2010 (KB2596517 is already updated and this was working from Mailbox 2013 and opening the PF on 2007 fine )
"The set of folders cannot be opened. The attempt to log on to Microsoft Exchange has failed."
I ignored the error (alas!) and completed Step 8 only to realise the error persisted. After which I had to follow the steps for roll back but the error persisted. I had to dismount the PF on 2007 and re-mount it to bring it back online.
Anyone else having similar issues and any advise?
Many thanks,
