Try this: Find Outlooks Custom View Menu - Outlook Tips

It is possible to customise Outlook 2007 including removing the View menu. Perhaps at some stage you meant to customise something else but accidentally dragged the View menu off the Menu bar.

If you click on the dropdown symbol at the end of an Outlook toolbar then Add/remove buttons & select Customise then select any other menu such as Go you will see that you can drag it away from its location or even right click & select Delete.

I therefore suggest that you search Outlook Help for Customise menu bar then choose Remove a toolbar, button, or menu. Look under the heading Remove a menu [where it states that menus can be restored] and the See also entries [which take you to Restore the original settings for buttons, commands, or toolbars which seems to me to be the bit you need].

Added later - Once you have the problem fixed, open File explorer and go to
%LocalAppData%\Microsoft\Office
then you can backup all the .qat files there after which you can go to
%UserProfile%\\AppData\Roaming\Microsoft\Outlook
to backup the outcmd.dat file
These files contain your QAT, menu & toolbar definitions. [there are explanations in Outlook Help - Where does Microsoft Office Outlook 2007 save my information and configurations?]

Best of luck,
Denis

It occurs to me that I assumed in my reply [above] that you had set [MS Office 2007] Outlook Help to offline i.e. to use the local Help file instead of the non-existent online help files.

In the bottom-right corner of the Help window you will see either Offline or Online. If you have previously selected Online then just click on it and select Show content only from this computer.
