I had upgraded to a new MacBook Pro 14" with M3 Pro Chip and Spotlight stopped working, which I initially noticed only in Outlook but later realized was all of Spotlight. What worked is at the very bottom, but I did the 2 steps below first, which might have made a difference.
THESE 2 STEPS ARE WHAT I TRIED WHICH WORKED INITIALLY THEN DID NOT WORK
I got my search reindex working by doing 2 things, one suggested by 3zabb and the other by Barbara Brannon (in this order).

I am running Sonoma 14.2.1 and Outlook Legacy.
I fixed this problem by:
- Click on Outlook on the toolbar [NOTE: I think 3zabb meant “Click on the Outlook menu”]
- Hover over Services
- Click Services Settings
- Open the Searching tab
- Checkmark Spotlight
- Click Done

To all those who have suffered this problem AND the lack of clear response from Microsoft Support about it --
I came upon some instructions from a few years ago when I first faced this issue. This method IS working, and it's worth remembering how to trick Spotlight into re-indexing a database (in this case, the Outlook 15 Profiles folder).
- From the Apple menu, choose System Preferences
- Click Spotlight
- Go to the Privacy tab
- Click the plus sign (+) to add a folder to the list of non-indexed folders
- (Here, search your computer for the Outlook 15 Profiles folder, which is located deep within a Library folder)
- If prompted for confirmation, click OK
- After a moment, select the item you just added to the list and click theminus sign (-) to remove it
- Close Spotlight preferences
- Rebuilding will take some time so make sure you leave your computer on for a while. You can use the computer while the search index builds.
In my experience this time, after a restart of my Mac and a relaunch of Outlook, the re-indexed items began reappearing little by little in a new search!
After numerous attempts over recent years to retain my carefully curated folder structure for an enormous database of emails, I do NOT recommend the method of selecting New Outlook and then immediately reverting to Legacy Outlook. Too much risk of corrupting the OLM database.
NOTE:
I did not restart my computer
I did not switch to “New Outlook” and back
The index initially rebuilt then disappeared the next time I woke my computer. It did not have search results in Outlook after a restart.
HERE IS WHAT WORKED:
I went to SYSTEM SETTINGS/Siri and Spotlight/Spotlight Privacy (way down at the bottom), There I chose to exclude "Macintosh HD" (my internal SSD) and restarted the computer. I then removed "Macintosh HD" from the exclusion list and again restarted the computer. It's all good now.
