I have problems with My Windows 7 OS
 I have installed Outlook and added 2 users in it. I am using this computer at home and so it is not connected to any domain. I have imported ‘.pst’ file from my old computer to the new computer’s Outlook which have a profile named ‘ABC’. It connects through POP and it is working properly. When I am login to another user name, DEF, it is not starting the Outlook and I am getting an error message which says ‘Default email folder is not able to open’. I don’t know why this is happening. Is there some problem with the importing of the ‘.pst’ file? If anybody knows the solution to solving this, please help me. I will be thankful for all your help.
