I just upgraded to Outlook 2010 from Outlook 2007 (Windows 7 Ultimate). All my messages in my Personal Folders came over fine. However, I can no longer send or receive emails on any of my accounts. I get the following error message: 0x8004010F 'Outlook Data File cannot be accessed'.
I have run scanpst.exe on my Outlook.pst file but that did not help.
I installed the 32 bit version of Outlook per the default settings.
