Can I uninstall Outlook on Mac?

Yes, you can delete Outlook, just like any other third-party app on your Mac. But keep in mind that dragging the app to Trash isn’t enough for a full uninstall. To remove Outlook completely, you also need to clean up its leftover files.nYou can do it manually by checking system folders for Outlook data, or much faster with an automated dedicated tool like App Cleaner & Uninstaller, which wipes out Outlook and all hidden files in a few clicks.

What happens if I uninstall Outlook - will I lose my emails?

No, uninstalling Outlook doesn’t delete your actual emails if your account is cloud-based (like Microsoft 365, Outlook.com, Exchange, or Gmail). Your messages, calendar events, and contacts stay stored on the server and will reappear once you sign in again.nWhat you do lose is the local cache Outlook keeps on your Mac - basically a copy of your mail data. That’s perfectly fine, and Outlook will rebuild it if you reinstall and log back in.nIf you use a POP account (rare these days), your emails might be stored only on your Mac. In that case, back them up first before uninstalling to avoid losing anything important.

What is Outlook and when to uninstall it

Outlook is Microsoft’s email client that bundles together mail, calendar, notes, and tasks in one place. It launched for Mac way back in 2010 (bundled with Office) and is still widely used today. It’s like a command center for calendars, video meetings, teams, reminders, and the full productivity toolbox, all synced from your Mac, iPhone, or the cloud.

But even smart tech can cause headaches:

Outlook gobbles up disk space – over 1 GB, sometimes a lot more, especially with big attachments or multiple accounts, which is crucial on Macs with limited space.
Mac users report constant crashes, memory spikes, and sluggish search, even on powerful new Macs. BTW, I would also complain if Outlook used too much RAM.
Outlook performance gets doubtful after macOS upgrades. Add in sync delays, missing calendar invites, or weird bugs, especially with Teams integration.
It’s as simple as your company switching email providers, or you’re swapping to something that works better for your workflow (think Mailbird, Spark, or Apple Mail).

Ways to remove Outlook

Method	Difficulty	Time	Removes leftovers
Manual	Moderate	10–15 mins	If you know where to look and don’t miss anything
Terminal	Hard	5–10 mins	Yes (if commands correct)
App Cleaner & Uninstaller	✅ Easy	✅ 30 seconds	✅ Full automatic cleanup

Uninstalling Outlook manually

Outlook scatters support files all over your Mac. To wipe it out fully, you need to track them down.

Quit Outlook.
Stop background processes.
Open Activity Monitor → search for Outlook → quit related tasks.
Delete the Outlook app.
In Finder, open the Applications tab → find & control-click Microsoft Outlook → select Move to Trash.
Clean leftovers.
In Finder’s menu, click Go → Go to Folder and type ~/Library/. Check the Library folder for Outlook files by com.microsoft.Outlook or just Outlook, and remove them.
Here are the directories where I found Outlook files on my Mac:
- ```
~/Library/Application Scripts/
```
  Copy
- ```
~/Library/Containers/
```
  Copy
- ```
~/Library/Group Containers/
```
  Copy
- ```
/private/var/db/receipts/
```
  Copy
- ```
/private/var/folders/
```
  Copy
  To find Outlook cache in this directory, type outlook in the search box, check the folders filter, delete cache starting with /private/var/folders/ and related to Outlook.
Note:
I checked Microsoft Outlook version 16.101.2 on Mac M3 Pro running on Tahoe. Since you and I may use different versions of Outlook and macOS, the directories can vary. So, it will not be excessive to double-check these paths:
- ~/Library/Application Support/
  
  Copy
- ~/Library/Caches/
  
  Copy
- ~/Library/Preferences/
  
  Copy
Empty Trash.

Uninstalling Outlook with Terminal

If you’re comfortable with commands, Terminal can wipe Outlook out in seconds. Just be careful, Terminal deletes files immediately with no undo.

Quit Outlook and stop all background processes using Activity Monitor.
Open Terminal (Applications → Utilities).
Remove the Outlook app by running this command:
```
sudo rm -rf /Applications/Microsoft\ Outlook.app
```
Copy
→ Enter your Mac password when asked.

Remove Outlook leftovers. Just be careful – mistyping commands can delete the wrong files. Run each of these lines and hit Return after each:

rm -rf ~/Library/Group\ Containers/UBF8T346G9.Office

Copy

rm -rf ~/Library/Group\ Containers/UBF8T346G9.ms

Copy

rm -rf ~/Library/Containers/CalendarWidgetExtension

Copy

rm -rf ~/Library/Containers/Microsoft\ Outlook

Copy

rm -rf ~/Library/Application\ Scripts/*Outlook*

Copy

rm -rf ~/Library/Application\ Support/CrashReporter/*Outlook*

Copy

rm rf /private/var/db/receipts/*Outlook*

Copy

rm rf /private/var/folders/*/*/*/*Outlook*

Copy

Deleting Outlook with a special uninstaller

This is by far the easiest method. With a dedicated tool like App Cleaner & Uninstaller, Outlook and all its traces disappear in seconds.

Get and open App Cleaner & Uninstaller.
Select Microsoft Outlook from the list of applications.
Hit Uninstall.
Review the list of files to be removed and confirm.

Already dragged Outlook to the Trash before? No problem. Do the following:

Switch to the Remaining Files tab.
Select the Outlook leftovers.
Click Remove → confirm removal.

Resetting Outlook with App Cleaner & Uninstaller

Like any app, Outlook can have its bad days. Maybe it crashes, perhaps it won’t sync, or probably it just feels buggy. In cases like that, a quick reset can do wonders. You can reset Outlook back to its default state in seconds using App Cleaner & Uninstaller:

Run App Cleaner & Uninstaller.
Locate Outlook among the applications and control-click it.
Select Reset Application from the dropdown.
Confirm to remove Outlook’s service files.

Final look

You’ve got three solid ways to uninstall Outlook on your Mac – each with its strengths. Manual cleanup works well if you know your way around macOS folders. But it takes time, and it’s easy to miss a file or two. Terminal is too risky, where one typo can cause trouble.

That’s when using App Cleaner & Uninstaller makes sense – it handles the job fast, complete, and by the book. With this tool, Outlook and any other app disappear in seconds – every cache, preference, and hidden folder included. Your Mac ends up cleaner, lighter, and ready for whatever comes next.
