Here is the link to the MS article

I see now it only refers to View menu commands disappearing rather
than the whole toolbar.
I'll describe how I have created to toolbar and button to clarify
I open a message
right click on the toolbar and pick Customise
Click New and call it "DocMan"
Then click on the Commands tab, select Macros and drag my macro onto
the custom toolbar
This has been working fine on my pc which is running outlook 2007, but
the other pc is running outlook 2000 ans the toolbar was running ok
for a couple of weeks, then last week it just disappeared. I recreated
the toolbar and button, but it wouldnt save it so when I closed
Outlook and re opend it I had to recreate the toolbar. Then all of a
sudden it started working ok again. Now yesterday it disappered again.
Any suggestions much appreciated
Regards
Grant
