Hi Mark,
CAUSE
This behavior may occur if the Outlwvw.dll file is missing or damaged, or
if the corresponding registry settings are damaged.
RESOLUTION
To resolve this behavior:
Outlook 2003
Start Outlook
On the advanced toolbar, click on the Outlook Today button. If the advanced
toolbar is not showing, click on the View menu, go to Toolbars and select
Advanced.
Right-click on the folder name that is selected and choose Properties.
Click the Home Page tab.
Click Restore Defaults, and then click OK.
Quit, and then restart Outlook.
Outlook 2002 and 2000
Start Outlook.
If the Outlook bar is not already displayed, click Outlook Bar on the View
menu.
On the Outlook bar, right-click Outlook Today, and then click Properties.
Click the Home Page tab.
Click Restore Defaults, and then click OK.
Quit, and then restart Outlook.
If the issue is resolved and the Outlook Today page appears when you start
Outlook (if it is configured as the default start page) or when you click
Outlook Today, do not follow the remaining steps in this article.
If the issue is not resolved, quit Outlook, and then go to step 7.
Rename the Outlwvw.dll file to Outlwvw.old:
Start Windows Explorer, and then locate the Outlwvw.dll file. The
Outlwvw.dll file is located in the following folder for your version of
Outlook:
Outlook 2003
C:\Program Files\Microsoft Office\Office11\1033
Outlook 2002:
C:\Program Files\Microsoft Office\Office10\1033
Outlook 2000:
C:\Program Files\Microsoft Office\Office\1033
NOTE: This is the default location of the Outlwvw.dll file. The location of
this file may be different on your computer.
Right-click the Outlwvw.dll file, and then click Rename.
Type outlwvw.old, and then press ENTER.
Quit Windows Explorer.
Restart the computer.
Repair the Outlook installation:
Insert the Microsoft Office CD-ROM into your CD-ROM or DVD-ROM drive. Press
and hold down the SHIFT key while you insert the CD-ROM.
Start Outlook.
On the Help menu, click Detect and Repair, and then click Start.
NOTE: When you start Outlook, the Detect and Repair feature may
automatically start and reinstall the file. You may not have to perform
this step to repair your installation of Outlook.
If you are prompted to do so, restart your computer.
Start Outlook. Make sure that the Outlook Today page appears when you start
Outlook (if it is configured as the default start page) or when you click
Outlook Today.
NOTE: You may have to restore the default Outlook Today home page settings.
To do so, follow steps 1 through 5 earlier in this article.
