Outlook 16.23.1 not searching correctly on Mojave 10.14.4

This is how I fixed this annoying issue for my env:

• Outlook 16.34
• Catalina 10.15.3

mdimport -i ~/Library/Group\ Containers/UBF8T346G9.Office/Outlook/Outlook\ 15\Profiles/Main\ Profile/Data/Tasks/

find ~/Library/Group\ Containers/UBF8T346G9.Office/Outlook/Outlook\ 15\Profiles/Main\ Profile/Data/Messages/ -type f -mtime -2 -exec mdimport -i "{}" ;

I wish you the best.

Slight typo in those commands; both paths are missing a space between "15" and "Profiles".  Here's the corrected commands:

mdimport -i ~/Library/Group\ Containers/UBF8T346G9.Office/Outlook/Outlook\ 15\ Profiles/Main\ Profile/Data/Tasks/

find ~/Library/Group\ Containers/UBF8T346G9.Office/Outlook/Outlook\ 15\ Profiles/Main\ Profile/Data/Messages/ -type f -mtime -2 -exec mdimport -i "{}" ;

Huni - step 7 of the link you provided suggests that I do precisely what my original question is about. Namely, that when I run the mdimport -g command in Mac OS 10.14.4 (Mojave), I get an error that the "-g" parameter is no longer supported. Specifically ...

'-g' no longer supported. Importers may only be tested by installing them.

This was the question I initially posed.

FYI, This problem seems to be resolved for my after upgrading to MacOS 10.14.5 and reindexing the outlook profile (see below steps).

After updating Mac OS to v10.14.5, you can re-add the account and check the result. If the issue persists, perform the following steps mentioned below to re-index the Outlook data folder and check if it resolves the issue. First let's quit Outlook completely and then open 'Terminal' and then copy - paste the below mentioned command:

sudo mdutil -E /

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 and check the behavior. Please, Quit Outlook completely and then try these steps:

1. Choose Apple menu > System Preferences, then click Spotlight.
2. Click the Privacy tab.
3. In Finder:

a. On the Go menu click Go to Folder...

b. Copy and paste the following location into the "Go to the folder:" dialog box and click Go:

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

4. Drag the ‘Main Profile’ folder to the Privacy tab. Once added, remove the folder, and Spotlight will re-index the folder. Note: You must perform this step for any additional profile folders you may have. The status of the re-indexing is not shown anywhere. so you need to wait for some time and check the result.

Thank you for this post. I had a similar issue but not caused during the update but after a Time Machine installation on a new Mac. Outlook did not search. I tried everything from this post and other posts as well. Only solution that managed to work for me was to delete Outlook App, delete Outlook containers and profiles. Just like written in here but only the Outlook part: https://support.office.com/en-us/article/uninstall-office-for-mac-eefa1199-5b58-43af-8a3d-b73dc1a8cae3 Afterwards I reinstalled Outlook and now it works just fine. It was a long process but I couldn't manage in any other way.

I don't see how I can continue to use Outlook if I can't search my mail.
