I upgraded 2 computers to the Office 365 February update: https://support.office.com/en-us/article/What-s-new-and-improved-in-Office-2016-for-Office-365-95c8d81d-08ba-42c1-914f-bca4603e1426?ui=en-US&rs=en-US&ad=US
Ever since then search is broken in Outlook on both computers - any search returns no results. Windows 10 search outside Outlook works fine. I've rebuilt the index, used ScanPST.exe and tried other things at https://lookeen.com/blog/how-to-fix-outlook-2016-search-problems and https://support.office.com/en-us/article/Reset-indexing-by-rebuilding-your-Instant-Search-catalog-213a2728-0ef4-427a-9bb2-aed329a59b17 but the problem remains on both computers.
Did February 2017 Office 365 update break Outlook Search?

Hi Mickey,
The incident Erick mentioned above mainly affects Outlook online mode and OWA(Outlook Web App). You can use your Office for Business account (Microsoft.yourdomain.onmicrosoft.com) to log into OWA(Outlook Web App) and see if the search function works fine there. If yes and the search issue only affects the Outlook desktop client from your side, the issue you’re encountering is not related to the incident and we apologize for delivering it in the first reply.
If the issue only affects the Outlook desktop client, please refer to the troubleshooting steps I mentioned above and please also share with us the requested information for troubleshooting.
However, if you really want to revert to an earlier version of Office 2016, you can refer to the article to do it. Reverting may cause data, settings and customizations losing, so we truly recommend you back up your mailbox data and Outlook settings before reverting Outlook.
Best Regards,
Aaron
The February 2017 version of Office 365 breaks searching of emails, as detailed at https://answers.microsoft.com/en-us/msoffice/forum/msoffice\_outlook-mso\_other/office-365-outlook-search-not-working-help/17bd8fca-0308-4c6e-9fb4-06d12e2bd0c1
How can you revert to the January 2017 version to get rid of this problem until Microsoft comes up with a solution? It seems you need a specific code for the version to which you want to return.
And does reverting lose your settings and customizations?
YES - Office update definitely breaks Outlook search!
Can someone explain what to do about this problem before Microsoft locks down the thread again? The Microsoft folks went silent after they asked for an email and it was not the same address as the one in their records. I gave them the onmicrosoft address on the account, but that is not hooked up to email (not sure at which end, and I never used it and forget how they pestered me into creating it). I gave them the order number, but they've gone silent.
Has Microsoft pulled the update?
Can we roll back to January without messing up all our customizations?
Did February 2017 Office 365 update break Outlook Search?
