Hello Don!
Removing and reinstalling MSN will not resolve the Inbox error that you’re getting since it will not target the damaged email synchronization file (SDF).
Please follow these steps instead for a Windows Vista or 7 computer:
1. Close all windows and click Sign Out at the top of the MSN window, then select Sign Out and Close.
2. Click on Start then inside the Start Search or Start search programs and files box at the bottom, type %USERPROFILE% and press Enter. If you get an error, please double-check the spelling and make sure that there are no spaces.
3. On the new window, please click on Organize at the top left hand corner then click on Folder and Search Options. This would open the Folder Options window.
4. In the Folder Options window, click on the View tab at the top. In the View tab, under Advanced Settings look for "Hidden files and folders" then click on "Show Hidden Files and Folders".
5. Just below "Show hidden files and folders", uncheck both "Hide extensions for known file types" and "Hide protected operating system files (Recommended)".
6. Click Yes on the Warning window. Then, click Apply and click OK to close the Folder Options window.
7. Double-click the folders in the following order:
> AppData
> Local
> Microsoft
> MSN
> db30
8. Arrange the files by type so it will be easier to locate the files we need. To do this, on the top left-hand corner of the window, click on the down arrow beside View then click on Details. After this click on Type at the top of the window to arrange the files by type.
9. Scroll down the list until you find the files that end with .SDF
10. Delete the two .SDF files that show your email address. To do this, right click the file and click on Delete
IMPORTANT: If you have other email accounts that have the same issue, please delete the .sdf files for the other email accounts.
11. Close all open windows.
After doing the above-mentioned steps, please continue with refreshing the local data storage as mentioned on this link: http://answers.msn.com/thread.aspx?threadid=1e24ba67-43eb-44af-a24d-8462d528464b
If the same orange triangle shows on the Inbox, please click on the triangle beside the Inbox and select More Information. Kindly copy the complete error information especially the one beginning with the hexacode 0x.
Feel free to reply to this post for any questions and feedback.
Thanks!
