Outlook 2013 indexing not up to date

Hi

You may want to rebuild the Outlook Indexing

Open outlook
Go in File tab
Then in Options
Click on Search
In the Source field, click on Indexing Option
Click on the Advance button

In the troubleshooting section, click on Rebuild.

Then reboot your PC.

Rebuild the index in Outlook 2013
Go to Outlook Settings (File | Options)
Go to the Search settings
Click on Indexing Options
Click Advanced
Click Rebuild
Click OK and then Close to dismiss the dialogs
Indexing will rebuild. It will takes some times to rebuild.

Hope this helps

Rebuilding the Windows Index should work. If you still have issues, go to Control Panel, Programs and Features, click on Office and do a Full Repair. After this, shut down, start back up and rebuild the index again.

If Exchange, make sure the OST file is up to date. You can move the OSB file to a USB key, and then restart Outlook to rebuild the OST file.

Hi Wilder1626 and Deadman,
I did what you suggested about 4 hours ago. Should I be thinking in terms of hours or days regarding how long it will take? I can't see any evidence that anything is happening. In the past, probably when I upgraded to Outlook 2013 or got a new computer I remember when I tried an email search I would get something like "Outlook is not finished indexing, results may be incomplete" I would get this for a few days until eventually it was finished indexing and any searches would include the latest emails. When I try a search now I'm not getting any such message. So I'm wondering is it actually doing anything. When I go into File>Options>Search>indexing Options the magnifying glass is moving and I see the attached screenshot showing 123,444 items indexed. I'm pretty sure this is exactly what I saw 4 hours ago.

I forgot the screenshot!

You might try Outllook in a new, test, Windows User Account (profile) and see if that works. It may possibly be a damaged Windows User Account.

Is it still running? 4 hours is long. You can always wait a little longer, just in case.

If you don't see any progress,  like John says, you may try Outlook in a new User Account see it this will work.

Hi John,
It is Outlook 2013 Office 365 Exchange online. I found the OST file. How do I know how up to date this is. This my main OST file. I have a few others.

Problem seems to be completely solved. Although Wilder1626 and John Hurst seem to be saying the same thing I followed Wilder1626's link and scrolled down to "Re-create an offline Outlook Data File (.ost)". I followed these instructions meticulously and the ost. file immediately started being rebuilt. My old ost. file size was over 3.3GB. It took about 5 hours to rebuild it but it stopped about 4% short of the old file size. This is probably good enough...I hope.

@Martin Campbell - Thanks for the update and I was happy to help.

@Martin Campbell, I'm glad i was able to help.

Hi again John and Jean-Marc,
I've asked a new question "Outlook 2013 contacts no longer searchable"
Obviously it's related to this one.
