After rebuilding MS Outlook Index, the search function is working again. Thanks for your contribution.
First of all, thank you for your article Eric.
I had this issue with Outlook 2016 and tried everything you explained without success. I think the problem relies upon the Outlook PST file.
When I click on it, in advanced properties, I check the “allow index” square and then apply, then I open outlook, but search still doesn’t work. Then I go back to my pst file and find that the index option is not checked.
Sorry, I forgot to say that in safe mode outlook search works perfectly
Now, I am using Outlook 2016 with Windows 10 OS without any searching issue.
I solved it, Eric !
It is from file .pst advanced properties. Must check allow indexing !!!
Hi,
I am having a problem like this.
Apart from the search function, some emails are missing from Outlook Mailbox. Due to the busy schedule, I haven’t taken backup of Outlook data file since last 15 days. So, it seems impossible to recover missing emails from Outlook 2016 folder.
Please help me as soon possible!
Thanks,

Follow the procedures as we have discussed in this tutorial for eliminating search issue. I hope, you would be successful to resolve this one ongoing issue.
But, Recovery of missing emails is possible through repairing damaged Outlook PST file.
That does not work on office 365 upgrade, only rebuilding the windows profile does the trick, tedious but other than that no go.
We have a ticket into Microsoft about this issue with no fix thus far.
Hi Eric,
I did entire work in the following steps:
1. Via ‘online mode’ Outlook 2016 is working fine for the search
2. index rebuild three times.
3. Remove unnecessary add-ins from MS Outlook menu bar
4. Now, I am enjoying the adequate search result.
Hi Eric,
I am at a total loss. i have run the scanpst on my main .ost folder, as well as the other folders and for a while it seems that the search indexes and then it just seems to reset and omit all Outlook results / indexing. it gets stuck at 53 297 item indexed, but i another some 140000 items in mail that are not indexed.
something odd is going on. i have checked the correct setting in the file / contents setting in indexing as well as rebuilt and restarted the PC numerous times. I have even recovered office on line (reinstall effectively) but this hasn’t helped either. please please can you help.
Hi Andrew,
Could you please let us the Outlook version you are working upon as solution varies from version to version.
Hi Eric,
It is version 16.0.6965.2058
I have now completely uninstalled and reinstalled and it is still unable to search in outlook 2016.
Looking forward to your assistance.
thanks

7. Now, Trick the radio button along “Index Properties and File Contents”.
8. Repeat the same procedure for ‘OST’ file.
9. Set “Plain Text Filter” and click on ‘OK’.
10. Close the application

It was the only solution that worked for me, then about a week later, Outlook 2016 search as back to not working again with the error “Search results may be incomplete”.
It works, but it doesn’t access the index, and you have to wait. I’m convinced there’s a bug because Outlook 2013 search works fine on Windows 10 PC and doesn’t crap out like this.
I have observed that the problem is related to damage in Outlook file. Can you help me on this one issue?
Sure!
You should go for Outlook repair tool.

Hi Eric,
My Outlook 2016 becomes nightmare for me. Its search functionality has stopped working since 1st may. I have tried all methods mentioned above but didn’t get the expected result.
However, I didn’t check PST corruption issue yet. I have no idea about ScanPST.exe file location.
Can you provide the location of Scanpst.exe as I want to try the last solution provided by you in this post?
Thanks in advance!
Hello Daniel,
In MS Outlook 2016, predefined location of ScanPST.exe is mentioned below:
For 32-bit Windows PC:
C:\Program Files\Microsoft Office\Office16\
For 64-bit Windows PC:
C:\Program Files (x86)\Microsoft Office\Office16\
Do let us know if the problem still persist.
Hi Eric,
My searching is still not working, and it’s too slow. It first shows the result of 2015, 2016 and it takes ages to show the latest one.
My outlook 2016 is already updated to the latest version(7870.2031) it says when I try to update it.
Tried modifying indexing, rebuilding everything but nothing fruitful.
Any suggestion would be really helpful.
Regards
Umesh
Hi Umesh,
If the search problem still exists, then create new Windows profile.
I have found rebuilding the windows profile has worked for my company.
How about outlook 2013 shared mailbox that my inbox emails will go missing and then returned after I restarted my Outlook.
Thank you.
Somehow Outlook users accidentally move the location of ‘outlook data file’. In this situation, you should restart Outlook again.
