Updating Outlook is a lot like changing the batteries in your smoke detector: it’s mildly annoying, easy to ignore,
and the moment you don’t do it, everything starts beeping at 2:00 a.m. (Except Outlook beeps with crashes,
login loops, and “Why won’t search find anything?” energy.)

The good news: updating Outlook on Windows (PC) or macOS (Mac) is usually a two-minute joband you can choose
automatic updates (recommended) or manual updates (for control freaks, IT policies,
or “my internet is powered by hamsters” situations). This guide covers both, including the
new Outlook vs classic Outlook on Windows, plus the Mac tools like
Microsoft AutoUpdate and the Mac App Store.

Why Updating Outlook Is Worth Your Time (Even When You’re Busy)

Outlook updates aren’t just “new emoji” (although yes, sometimes it feels like that). Updates typically include:

• Security patches that protect your mailbox and device
• Bug fixes for crashing, freezing, slow startup, or broken search
• Compatibility updates for Windows/macOS changes, Exchange, Microsoft 365, and add-ins
• New features (especially if you’re on Microsoft 365)

Translation: staying updated helps Outlook behave like a helpful email assistant, not a dramatic theater kid.

Step 1: Identify Which Outlook You’re Using

This is the secret to updating Outlook correctly, because “Outlook” can mean different things depending on your setup.

On Windows (PC): New Outlook vs Classic Outlook

• New Outlook for Windows is typically installed/updated like an app (often through the
  Microsoft Store). It has a more modern look and is closely tied to cloud services.
• Classic Outlook is the traditional desktop version included with Microsoft 365 or Office
  (like Office 2021/2019/2016). It updates through Office’s updater (Click-to-Run) or Windows Update (for some older MSI installs).

Quick clue: If you see a toggle that says something like “Try the new Outlook,” you’re probably in classic Outlook.
If the whole interface feels new and app-like, you may already be in new Outlook.

On Mac: Microsoft AutoUpdate vs Mac App Store

• If you installed Microsoft 365/Office from Microsoft, Outlook updates through Microsoft AutoUpdate.
• If you installed Outlook from the Mac App Store, updates typically come through the App Store’s update system.

How to Update Outlook on Windows Automatically

Automatic updates are ideal because they happen quietly in the background, like a competent roommate who replaces the toilet paper
without making a speech about it.

Option A: Classic Outlook (Microsoft 365 / Office) Automatic Updates

1. Open Outlook (classic) or any Office app (Word works too).
2. Go to File > Account (or Office Account).
3. Look for Office Updates and Update Options.
4. If you see Enable Updates, click it. This turns automatic updates back on.
5. Once enabled, Outlook updates automatically when Office downloads and installs updates.

Note: On some work/school devices, IT may manage updates. If buttons are missing or locked, that’s usually policynot you.

Option B: New Outlook for Windows Automatic Updates via Microsoft Store

If your new Outlook is installed as a Store app, updates typically happen automatically through Microsoft Store app updates.
Many systems keep Store apps updated in the background.

If you want to confirm auto-updates are enabled:

1. Open Microsoft Store.
2. Go to Settings.
3. Make sure App updates (automatic updates) are turned on (wording can vary by Windows version).

Option C: Older MSI-based Office installs Updates via Windows Update

Some perpetual or older MSI-based Office installations receive updates through Windows Update/Microsoft Update rather than the in-app Office updater.
If that’s your setup, keep Windows Update running and ensure you’re receiving updates for Microsoft products.

How to Update Outlook on Windows Manually

Manual updates are great when you’re troubleshooting, you suspect you missed a patch, or you simply enjoy pressing buttons that say “Update Now.”

Manual Update: Classic Outlook (Microsoft 365 / Office desktop)

1. Open Outlook (classic).
2. Click File > Office Account (or Account).
3. Under Product Information or Office Updates, select Update Options.
4. Click Update Now.
5. Wait while Office downloads and installs updates.
6. Restart Outlook when prompted (or restart your PC if things feel “sticky”).

If you don’t see “Update Now”: click Enable Updates first (if available), or check whether your Office version is managed by IT.

Manual Update: New Outlook for Windows (Store app)

1. Open Microsoft Store.
2. Click Library (usually on the left).
3. Select Get updates (or Update all).
4. Let the Store download and install available updates, including Outlook.
5. Reopen Outlook.

Tip: If Outlook says something like “Update to keep using Outlook,” it’s often pointing to Store updates for the new Outlook app.

How to Update Outlook on Mac Automatically

Option A: Microsoft AutoUpdate (Most Microsoft 365 / Office installs)

On macOS, Outlook updates are commonly handled by Microsoft AutoUpdate (MAU). Once set, it checks for updates automatically.

1. Open Outlook or another Microsoft app like Word.
2. On the top menu, select Help > Check for Updates.
3. When Microsoft AutoUpdate opens, check the box for Automatically keep Microsoft apps up to date.
4. Close the window. MAU will handle updates going forward.

Optional (advanced): Some versions of MAU let you choose channels (like Current, Preview, or Beta). If you value stability, stick with
the standard/current channel. If you enjoy living on the edge, Preview/Beta existsbut don’t blame your inbox when it gets adventurous.

Option B: Mac App Store Version Automatic Updates

If Outlook was installed via the Mac App Store, it usually updates through the App Store update settings.

1. Open App Store.
2. Choose App Store > Settings.
3. Enable Automatic Updates (wording may vary slightly).

How to Update Outlook on Mac Manually

Manual Update: Microsoft AutoUpdate

1. Close Outlook (optional, but helpful if you’re troubleshooting).
2. Open Outlook (or Word), then go to Help > Check for Updates.
3. In the Microsoft AutoUpdate window, click Check for Updates if needed.
4. Click Update (or Update All) and wait for installation to finish.
5. Reopen Outlook.

Manual Update: Mac App Store

1. Open App Store.
2. Click Updates (or go to your account page where updates appear).
3. Click Update next to Outlook, or Update All.

How to Confirm Outlook Actually Updated

Sometimes you click update, everything looks normal… and you still wonder if anything changed. Totally fair.
Here’s how to verify the version.

Check version on Windows

1. Open Outlook.
2. Go to File > Office Account.
3. Look for About Outlook (or version/build info in Product Information).

Check version on Mac

1. Open Outlook.
2. On the menu bar, choose Outlook > About Outlook.
3. Review the version number/build.

If you’re troubleshooting a specific bug, version numbers matter. Support teams love them almost as much as they love asking if you restarted your device.

Common Update Problems (and Fixes That Don’t Require Screaming)

1) “Update Options” or “Update Now” is missing on Windows

• You might be on an IT-managed device. Some organizations control Office updates centrally.
• Updates may be disabled. If you see Enable Updates, click it.
• MSI-based Office install. Updates may come via Windows Update rather than inside Outlook.

2) Update downloads but Outlook still misbehaves

• Restart Outlook (and ideally your computer).
• Disable add-ins temporarily (some add-ins don’t love change).
• Consider running an Office Repair on Windows:
  • Go to Settings > Apps > Installed apps.
  • Select Microsoft 365 or Office > Modify.
  • Try Quick Repair first; use Online Repair if needed.

3) Microsoft Store won’t update new Outlook

• Make sure you’re signed into the Store.
• Open Library and press Get updates again.
• Restart Windows and retry.
• If it’s stuck, Store troubleshooting may help (it’s not glamorous, but it’s effective).

4) Microsoft AutoUpdate on Mac throws errors

• Try opening MAU again via Help > Check for Updates.
• Install the latest Microsoft AutoUpdate if prompted.
• If errors persist, MAU troubleshooting steps often involve reinstalling the updater component and checking permissions.

5) “I updated Outlook and now it looks different”

Some updates adjust layout, fonts, or default behaviors. If you moved from classic to new Outlook (or got a major UI update),
take five minutes to re-check:

• Notification settings
• Focused Inbox
• Reading pane preferences
• Signature formatting
• Add-in availability

Think of it as Outlook rearranging the furniture. The couch is still thereit’s just… somewhere emotionally different.

Pro Tips for Updates That Don’t Ruin Your Day

• Update when you can restart. Many fixes apply cleanly after a restart.
• Don’t mix channels unless you mean it. Preview/Beta can be useful, but stability matters for most people.
• Back up important data if you’re doing major repairs. Updates normally preserve your mail/profile, but repairs or profile rebuilds can be disruptive.
• If you’re on a work device, ask IT before forcing changes. “I found a button and I pressed it” is not always a corporate-approved workflow.

FAQ: Quick Answers to Common Outlook Update Questions

Does updating Outlook delete my emails?

Typically, no. Updates are designed to preserve your accounts, mailbox data, and settings. Still, if you’re doing repairs
or profile rebuilds, it’s smart to know where your data lives (especially for POP accounts or local archives).

How often should I update Outlook?

If automatic updates are on, you don’t need a schedule. If you’re updating manually, checking monthly is reasonablesooner if
you hear about a security patch or you’re troubleshooting issues.

Why does Outlook on Windows update differently on two computers?

They may have different Outlook types (new vs classic), different Office installation methods (Click-to-Run vs MSI),
or different IT policies controlling update channels.

What’s the safest approach for most people?

Turn on automatic updates and manually trigger an update only when you suspect you’re behind or you’re fixing a problem.

Real-World Update Experiences (Because This Is Where the Plot Twists Live)

Let’s talk about what actually happens in the wildwhere people have deadlines, eight open browser tabs, and an Outlook inbox
that looks like a museum exhibit titled “Unread Messages: A Tragedy in 4,000 Parts.”

Experience #1: The “I’m Updated… I Think?” spiral.
A common scenario: Outlook starts acting weirdsearch returns nothing, calendars don’t sync, or the app feels sluggish.
You go to update, and it claims you’re already up to date. That’s when the detective work starts. On Windows, the first
question is whether you’re on new Outlook (Store updates) or classic Outlook (Office updates). I’ve seen
people update Office religiously while the new Outlook app quietly stays outdated in the Microsoft Store like a houseplant
nobody waters. The fix is usually simple: open Microsoft Store, go to Library, hit “Get updates,” and suddenly Outlook
remembers how to behave.

Experience #2: The corporate laptop with “mystery settings.”
On managed devices, the Update Options button may be missing, grayed out, or replaced by the emotional equivalent of a
“No Touchy” sign. This isn’t Outlook being rudeit’s policy. Organizations often control update channels to avoid breaking
add-ins or line-of-business integrations. The best real-world move: don’t fight the policy; document the problem, grab your
Outlook version/build number, and send it to IT. The fastest fixes happen when you give them specifics rather than
“it’s broken-ish.”

Experience #3: The Mac AutoUpdate window that pops up at the worst time.
Microsoft AutoUpdate on Mac is generally solid, but it has comedic timing. It loves appearing when you’re about to present,
join a meeting, or finally answer that email from last Thursday. The practical strategy is to let AutoUpdate run when you
can close Outlook for a momentlike right after lunch or at end-of-day. And if AutoUpdate errors out, don’t panic: reopening
Help > Check for Updates often clears transient issues. If it keeps failing, reinstalling the updater component is a
classic “annoying but effective” remedy.

Experience #4: “After the update, my Outlook looks different.”
This is where people assume they “broke something,” but it’s often just a feature update. The most common complaints are
signature formatting changes, layout adjustments, or settings that feel reset. The best habit here is to keep a tiny
checklist of your must-have preferences: reading pane position, message preview settings, Focused Inbox, and your signature.
A five-minute reset beats a week of quietly resenting your email client.

Experience #5: The “update fixed it” surprise.
Sometimes the story ends beautifully: Outlook crashes? Update. Attachments won’t open? Update. Search is slow? Updateand then
restart. It’s not glamorous, but it’s the digital equivalent of tightening a loose screw. Most users don’t need a deep dive
into channels and build numbers; they need a reliable process. Automatic updates cover the daily maintenance, and manual
updates are your “break glass in case of weirdness” option.

Bottom line: updating Outlook isn’t about chasing shiny new buttons. It’s about keeping your inbox stable, secure, and
less likely to sabotage your day with a surprise meltdown.

Conclusion

If you want the simplest life: turn on automatic updates and let Outlook quietly improve itself in the background.
If you want control (or you’re troubleshooting): use the manual stepsOffice Account on Windows for classic Outlook,
Microsoft Store for new Outlook, and Microsoft AutoUpdate or App Store on Mac. Either way, staying current is one of the
easiest ways to reduce crashes, fix glitches, and keep your email flowing like it’s supposed to.
