Search function in Outlook doesn't work after upgrading to Windows 11

After upgrading, I found search results suggesting that if the Outlook search doesn't work after upgrading, to go "search", then "Search Tools", then "Indexing Status" &  then it says "Currently indexing 24,608 items indexing...but nothing happens.  As a workaround it suggests finding 4 registry keys & deleting them BUT none of these are seen so I have no idea what to do next.

Of course, the only reason I upgraded to Windows 11 was Microsoft pushing me, now I cannot search in Outlook which is important to me.

Any ideas??

Thank you,

Randy
