OutlookSearchRepair for Mac: Is It Still Available, and What Do You Use Instead?

No, OutlookSearchRepair is no longer available, and it would not run on a current Mac if you found a copy. Microsoft's note on the tool says it stopped working with macOS Mojave (10.14), and its download link on download.microsoft.com returned “404 Not Found” when we checked on 21 October 2026. You can still do exactly what it did, by hand: check for duplicate copies of Outlook with mdimport -L, then reindex your Outlook profile with Microsoft's mdimport -g command. The steps are below. If you use new Outlook for Mac, you do not need any of this.

What OutlookSearchRepair was

OutlookSearchRepair was a small utility that the Office for Mac support team released in August 2017 for Outlook 2016 for Mac. Microsoft later listed it in an “Outlook for Mac support tools” article, next to utilities that reset Outlook's preferences, made Outlook the default mail app and cleared recent addresses, and described it in one line: it “repairs search results within Outlook”. You were meant to run it when search in Outlook showed nothing, or only older items, even for a message you already had open.

It existed because legacy Outlook for Mac does not keep its own search index. It hands that job to Spotlight, the macOS search index. When Spotlight's copy of your Outlook data is incomplete or damaged, Outlook search comes back empty even though your mail is fine. The tool did two things about that, in this order:

1. It looked for duplicate installations of Outlook. If it found any, you removed the extra copies and restarted the Mac.
2. You clicked Reindex. It showed “Reindexing, please wait” while Spotlight rebuilt the index of your Outlook profile, which could take an hour or more, and finished with “Done! Reindexing has completed!”

Both steps are still possible without the tool, which is why its disappearance matters less than it seems.

Is OutlookSearchRepair still available?

No. This is what we found on 21 October 2026:

• The download is gone. The tool's download link, download.microsoft.com/.../OutlookSearchRepair.zip, returns 404 Not Found.
• So is the page that offered it. Microsoft's “Outlook for Mac support tools” article, which carried the download link and the instructions, now returns a “Content not found” page on learn.microsoft.com.
• One Microsoft article still names it. Troubleshoot search issues in Outlook for Mac, last updated in September 2026, still says “Run the OutlookSearchRepair utility” as its first step, but no longer links to it. That is why people still search for it. The rest of that article is the replacement, and it is what the steps below follow.

Copies of OutlookSearchRepair.zip on third-party download sites are not distributed by Microsoft, and even a genuine copy would not work on any macOS release since 2018. There is nothing to gain from installing one.

Does it work on current macOS?

No. Microsoft's note on the tool said that, because of changes in macOS Mojave, it no longer works on 10.14 and higher. Mojave was released in 2018. Every later version, including Catalina, Big Sur, Monterey, Ventura, Sonoma, Sequoia and Tahoe, is covered by that note. If you are on any of them, skip the tool and go straight to the steps below.

First, check which Outlook you have

OutlookSearchRepair, mdimport and every Spotlight fix only affect legacy Outlook for Mac, the version that searches through Spotlight. Microsoft now calls the current app simply Outlook for Mac, and its search is powered by Microsoft Search instead.

• If the Help menu shows Revert to Legacy Outlook, you are on new Outlook. Skip to the section on new Outlook below.
• If you see a Legacy Outlook switch that is turned on, you are on legacy Outlook, and the steps below apply.

Microsoft has also announced that, starting October 2026, legacy Outlook for Mac stops working with Exchange Online mailboxes, because the Exchange Web Services it relies on are being retired; with on-premises Exchange it keeps working until 9 October 2029 (Microsoft's end-of-support page). If your mailbox is a Microsoft 365 work or school account, switching to new Outlook is the lasting fix for Spotlight search problems as well.

What to use instead: reindex Outlook for Mac step by step

These steps follow Microsoft's current support article for legacy Outlook for Mac, in order. Stop as soon as search works again.

1. Let indexing finish

If you recently added an account, created a profile, or imported a PST or OLM file, Spotlight may simply not have finished indexing it. Outlook shows “No Results” while that is in progress. Leave the Mac on and connected to power for a while, then search again.

2. Check the profile name

A profile name containing a special character such as a slash (/) can stop Spotlight from indexing it. To see the name, open Finder, go to Applications, Control-click (or right-click) Microsoft Outlook, choose Show Package Contents, then open Contents, SharedSupport and Outlook Profile Manager. If the name has a special character, quit Outlook and rename the profile's folder in ~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/.

3. Make sure Spotlight is allowed to index the profile

Open the Apple menu, choose System Settings, then click Spotlight (or Siri & Spotlight) in the sidebar. At the bottom of the window, click Search Privacy (or Spotlight Privacy). If your Outlook profile folder, or any folder above it, or your whole disk is in that list, Spotlight is not indexing it. Select it, click the remove button (−), and click Done.

4. Look for duplicate copies of Outlook

This replaces the first thing OutlookSearchRepair did. Restart the Mac, which also restarts Spotlight. Then open Terminal (Finder, Applications, Utilities, Terminal), type this command and press Return:

mdimport -L

It lists every Spotlight importer on the Mac. If “Microsoft Outlook Spotlight Importer.mdimporter” appears more than once, you have more than one copy of Outlook. Delete the copy you do not use, empty the Trash, restart the Mac, and start again from step 1.

5. Reindex your Outlook profile with mdimport

This replaces the Reindex button. In Terminal, run Microsoft's command below, with your Mac user name in place of <user_name>:

mdimport -g "/Applications/Microsoft Outlook.app/Contents/Library/Spotlight/Microsoft Outlook Spotlight Importer.mdimporter" -d1 "/Users/<user_name>/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/Main Profile"

The path after -g is where Outlook is installed by default, and the path after -d1 is your profile. Main Profile is the default profile name; if you renamed your profile or installed Outlook somewhere else, change those paths to match. If you are not sure of your user name, type whoami in Terminal. When the reindex has finished, quit and reopen Outlook.

6. No Terminal? Use Spotlight's privacy list

Microsoft also gives a method with no commands, which reindexes the same folder:

1. Open System Settings, click Spotlight (or Siri & Spotlight), then click Search Privacy (or Spotlight Privacy).
2. In Finder, choose Go, then Go to Folder, paste ~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/ and press Return.
3. Drag the Main Profile folder (or the folder with your profile's name) into the privacy list.
4. Wait a few seconds, select it in the list, click the remove button (−), then click Done. Spotlight now reindexes that folder.
5. Repeat for any other profile folders you use.

Microsoft notes this can take several hours, depending on how much email you have.

7. Last resort: reinstall

If you have given Spotlight enough time and Outlook search still finds nothing, Microsoft's final step is to uninstall and reinstall Office for Mac. Before that, a full Spotlight rebuild of the whole disk is worth one try; our guide to Outlook for Mac search not working covers it, along with recreating the profile.

How long does reindexing take?

Plan for an hour or more. Microsoft said OutlookSearchRepair itself could need an hour or more depending on the size of the profile, and the privacy-list method several hours for a large mailbox. Apple says building a Spotlight index can take hours, or days for a lot of data, and that it goes faster while the Mac is idle, plugged in and online. Outlook search can be slow or incomplete until it is done, so it is best started at the end of the day. If indexing seems stuck rather than slow, see Outlook search indexing slow or stuck.

If you use new Outlook for Mac

New Outlook for Mac does not search through Spotlight, so OutlookSearchRepair, mdimport and Spotlight rebuilds make no difference to it. If its search misses email, try the same search in Outlook on the web at outlook.office.com. If it fails there too, the problem is not your Mac; see why Outlook search does not find emails that exist and every fix for Outlook search not working.

Search that does not depend on Spotlight

A Spotlight reindex tends to be a fix you repeat, often after a macOS update. Inbox Search is an Outlook add-in that builds its own index of your mailbox on your device and searches it from inside Outlook, so it does not rely on Spotlight at all. It works in Outlook on Windows, Mac and the web, and your email content is not sent to our servers.

Frequently asked questions

Where can I download OutlookSearchRepair?

Nowhere official. Microsoft's download link for OutlookSearchRepair.zip returned 404 Not Found on 21 October 2026, and the Microsoft page that offered it has been removed. Copies on other download sites are not from Microsoft, and the tool does not work on macOS Mojave (10.14) or later anyway.

Does OutlookSearchRepair work on macOS Sonoma, Sequoia or Tahoe?

No. Microsoft's own note on the tool says it no longer works on macOS Mojave (10.14) and higher, because of changes Apple made in Mojave. Sonoma, Sequoia and Tahoe are all later releases.

What replaced OutlookSearchRepair?

Two Terminal commands from Microsoft's own support article. mdimport -L checks for duplicate copies of Outlook, which is what the tool checked first, and mdimport -g reindexes your Outlook profile in Spotlight, which is what its Reindex button did. Without Terminal, add your profile folder to Spotlight's privacy list and remove it again.

How long does it take to reindex Outlook on a Mac?

Expect an hour or more, and several hours for a large mailbox. Microsoft said OutlookSearchRepair could need an hour or more depending on the size of the profile, and that the privacy-list method can take several hours depending on how much email you have. Search may be slow or incomplete until it finishes.

Do I need OutlookSearchRepair in new Outlook for Mac?

No. Microsoft says search in new Outlook for Mac is powered by Microsoft Search, not Spotlight, so OutlookSearchRepair, mdimport and Spotlight rebuilds do not change it. They only apply to legacy Outlook for Mac.
