Question : Can not expand the folder.  The attempt to log onto Microsoft Exchange failed.

All of a sudden one of my users is getting a the above message when she tries to open public folders.  She is logged into Exchange and able to send and receive mail.  She is in cached exchange mode but gets it when she clicks on all public folders.  She can see Public Folders when she goes into OWA.  I have deleted her .OST file, I have recreated her outlook profile and we have even changed her password none of which solved the problem.  Any ideas?

You can install nested ESXes but you cannot install 64Bit VMs in the nested ESX. Just 32 Bit VMs are possible.
