After upgrading from Office 2007 to Office Pro Pluys 2010, all of my email accounts, folders, messages, etc...showed up fine. I decided to add my work email account (an Exchange account), and it added successfully and began updating to bring those message over. While it updating, I decided I did not want that email account on Outlook, so I went to Account Settings and deleted it. After restarting Outlook, I got this message,



“Cannot open your default e-mail folders. Outlook cannot start because a data file to send and receive messages cannot be found. Check your settings in this Microsoft Outlook profile. In Microsoft Windows, click the Start button, and then click Control Panel. Click User Accounts, and then click Mail. Click Show Profiles, select this profile, and then click Properties.”


I followed those instructions but did not find "Mail" in the "User Accounts" window. I have only one Account/Profile on this system; Administrator.



I have completely uninstalled Office 2010, rebooted, installed Office 2007, then upgraded to 2010 again but continue getting the same error message.


Any help is greatly appreciated!


I'm running Windows 7 Ultimate 64bit
Was upgrading to Office Pro Plus 2010 32 bit

You'll actually want to go Start > Control Panel > Mail. I'm not sure why it would mention User Accounts in there, as there is no link to the Mail settings from User Accounts.

Once clicking on Mail, you'll want to click on the Data Files button. There you should see a list of the data files being used. I'm guessing that the default will be the Exchange .OST file that didn't get properly populated. You'll want to click on the .PST file associated with the email account you want to keep, and click "Set as Default". You should probably remove the .OST file for your Exchange account as well.

Hope this helps.
