IT WORKS AGAIN!! THANKS

I tried the new outlook but i'm unable to import my existing emails :/ account is a pop account so that is def not a solution for me

I have been in contact with microsoft support and these are their instructions moments ago. I'm currently doing the re-indexing Thanks for letting us know. We'll need to re-install Outlook so that the Outlook search configurations for Spotlight search can be re-created. Can you please download the Office 365 installer using the following link: https://go.microsoft.com/fwlink/?linkid=525133 Then delete your "Microsoft Outlook" app from the /Applications folder. Your mailbox data files are stored at another location and will remain intact. Make sure to empty your trash folder so that the "Microsoft Outlook" app is fully uninstalled. Run the Office 365 installer that you downloaded. Then please follow the steps below to re-index your Outlook Profile: Choose Apple menu -) System Preferences, then click Spotlight. Click the Privacy tab. 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/ Drag the ‘Main Profile’ folder to the Privacy tab. Once added, remove the folder from the same Privacy tab, and Spotlight will re-index the folder. Note: You must perform this step for any additional profile folders you may have. See the following article from Apple to learn more: https://support.apple.com/en-us/HT201716 Allow some time for the re-index, as this is happening in the background, with no visible indication and the duration depends on the amount of content. A few hours should be about enough for a re-index and then try searching again.
