I didn’t realize how much I use the tool bar in Outlook, but once it was gone, I felt crippled. I have no idea why I lost the toolbar. Corrupt file maybe? Even when I went into the Customize Toolbars dialog box, it was gone:
- Close Outlook
- Open your C:\Users\usernamehere\AppData\Roaming\Microsoft\Outlook directory
- Rename the file outcmd.dat to outcmd.dat.old
- Restart Outlook
Standard toolbar restored. Likely any other toolbar customizations you may have done are now gone/reset.
