Can't Search Outlook PST files after upgrade from Outlook 2016 to Outlook for Office 365 MSO RRS feed

  • Question

  • Hi,

    We are having some trouble searching through PST files that we have stored on a network server after upgrade our clients from Outlook 2016 VL 32-bit to Outlook for Office 365 MSO (16.0.11929.20396) 32bit. We have users on either version of Windows (7 & 10) that after this upgrade installation, they (including myself) are unable to search through PST Files/archive files. The search appears to work perfectly fine on the Inbox of the OST, It just appears there are issues with specifically PST files. 

    What I've tried to do to remedy the issue were the following:

    - Restarting the PC and Outlook for Office 365

    - Checking Indexing status

    - Selecting "Rebuild Index" in the advanced section of Index Options (Which appears to not work?)

    - Stopping the Windows Search Service, Backing up the Search folder from C:\ProgramData\Microsoft\, and Deleting the folder to force a index rebuild. (I swore this would work, but apparently not)

    - Testing removing "Microsoft Office - <Username here>" from the "Modify" section in Indexing options, restarting the Outlook Application, and testing search in the PST files (Which partially works but leaves a "search is not working right now" message up, takes very long depending on archive size, and doesn't return all but some results)

    I could really use some help with this! Thanks!

  • Hi,

    It is not recommended to put the PST file on the network server since this may corrupt your PST file. So it is suggested to move your PST file to local and test to see if you can search the PST file normally.

    If the issue persists, then please directly open this PST file in Outlook to see if the PST file is corrupted.

    • If the PST file is corrupted, please try reparing your PST file.
    • If the PST file is not corrupted, then there may be something wrong with your search tool, please start your Outlook in safe mode (Press Win + R, type “outlook /safe”, press Enter.) and see if the issue continues.


    If the issue is fixed after you put the PST file to local, then please just put it here and don't move it to the network server again.

    Besides, there are some other methods you can try:

    1. Creating and using a new Outlook profile via Control Panel > Mail > Show profile and see if there is any difference.
    2. Repair your Office installation.


    Hoep this can be helpful.
