Usually, we tend to look at the registry when there’s a problem with any particular software, and that’s true for this particular issue. However, jumping directly to the registry shouldn’t be your first option since there’s another way that could do the trick.

The first step here is to navigate to Outlook Options via the program itself; the hit the Search tab situated in the left-pane. After that, click on Indexing Options, then select Microsoft Outlook. To move forward, tap the Modify button below then select Microsoft Outlook again by ticking the box beside it.

Click OK, and that should be the end of your problems.

Check Group Policy Setting

While at it, you might want to also have a look at at the Group Policy settings and make a slight change if needed.

Run gpedit.msc to open the Local Group Policy Editor and navigate to the following setting:

Computer Configuration > Administrative Templates > Windows Components > Search

In the right side, you will see Prevent indexing Microsoft Office Outlook. Ensure that it is set to Not Configured or Disabled.

That’s it really. Everything should be up and running right now with problems, or little problems. Just make sure to follow the instructions properly.
