Outlook for Mac 2019 - Search not working :-(

I connected with MS support and here is the reply I got that worked for me MAC 2019 Stand alone Office.

Hi, thank you for contacting Outlook for Mac support. My name is Chaithra and I will be assisting you today. Please note this is an Offline support and the responses will be delayed.

Before proceeding, I would like to keep you informed that Outlook for Mac does not have its own search engine, rather it take the help of spotlight to search. So, let’s try re-indexing the spotlight search and check if the search works fine.

Referring to your concern, please follow the below steps and run the provided command:

1. Restart the computer and log into the user.

2. Make sure Outlook is quit after the restart.

3. Launch Terminal found within the Applications folder.

4. Make sure the user you are logged in as is an administrative user. If not you can use the "su" terminal command to switch to an admin user.

5. In Terminal type the following.

sudo mdutil -E /

(Note: The volume name must be changed to the name of your startup volume.)

It will prompt for your Mac password. Please enter it and wait for it to complete. You will see 'Indexing enabled' message. Once this is done, re-index the Outlook data folder once again and check if it resolves the issue. Please, Quit Outlook completely by click on Outlook Menu -- Quit Outlook and then try these steps:

1. Choose Apple menu -- System Preferences -- Spotlight -- Privacy.

2. In Finder menu under the Go menu click "Go to Folder...". Copy and paste the following location dialog box and click Go:

"~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/"

3. Drag the ‘Main Profile’ or if you have created any profile and made a default profile folder to the Privacy tab. Wait 5 seconds then remove the folder, and Spotlight will re-index the folder.

4. Launch Outlook and perform a search. Wait for at least 10 minutes as the search results should start to slowly appear as each email in the profile is indexed. Note there is no status indication for the re-indexing. The re-index will just silently finish in the background.

Let me know if this helps.

Thanks!
