Microsoft 365 keeps trying to update

Microsoft 365 keeps trying to update when the installed app, update channel, or device management policy does not match the update source. The fastest first step is to open File > Account in Word, Excel, or another Microsoft 365 app, then select Update Options > Update Now. If the prompt returns after that, the next fix depends on whether the install is home, business, or company-managed. (Microsoft Support)

Microsoft 365 update loop explained

The repeated prompt usually means the update path is out of sync, not that Office is broken. On a home install, the issue is often a missing update command, a disabled update setting, or a failed connection to the Office Content Delivery Network. On a managed install, the channel or policy may control the result.

What to check first

1. Open Word, Excel, or another Microsoft 365 app.
2. Go to File > Account.
3. Look for Update Options.
4. If it is present, choose Update Now.
5. If Microsoft says the update is finished, close the status window.

Say your laptop shows “Updating Office” every time Word opens, but the version number never changes. That points to a stuck update loop, not a fresh update request. If the same machine is on weak hotel Wi-Fi, the update may start, fail, and prompt again after the next launch.

What is most likely causing it?

Most often, the cause is a mismatch between what the app expects and where updates come from. Less often, the install is controlled by policy, or the update download path is blocked. If apps will not open at all, the update problem may be secondary to a damaged Office install.

Likely causes, from most to least common

• Update Options is missing or hidden because the install is managed differently.
• Update Now runs, but the same prompt returns because the update did not complete cleanly.
• A company device or volume license install is controlled by Group Policy or an admin tool.
• The Office CDN path is blocked, or the connection drops during download.
• Office apps will not open, so the normal update path cannot finish.

Update Options is missing

If Update Options is absent, do not assume the app has no update path. A missing button can point to a volume license install or Group Policy management. In home or small-business installs, Microsoft also says updates may need to be enabled first before the normal command appears.

1. Open a Microsoft 365 app and go to File > Account.
2. Look for any text that suggests updates are turned off.
3. If you see Enable Updates, select it first.
4. If the menu remains missing, open Windows Update or Microsoft Update and check whether Office updates are listed there.
5. If the device belongs to a business, stop here and contact IT.

Manual update path

Use the manual Office Updates download only when the in-app menu is absent or the normal path fails. That is a fallback, not the preferred route. If the install is managed, Microsoft recommends Microsoft Update or help desk support instead of trying to force a local change.

1. Close all Office apps.
2. Open the Office Updates page in a browser.
3. Download the update package that matches the installed Microsoft 365 build.
4. Run the installer and let it finish.
5. Restart the app and check File > Account again.

Why does Update Now keep returning?

If Update Now appears to finish and then comes back later, the update may have completed only partly, or the app may be switching between update channels. A channel mismatch, such as Current Channel versus Monthly Enterprise Channel, may make the app appear updated while the next launch still requests a different package.

Steps to isolate the loop

1. Run File > Account > Update Options > Update Now.
2. Wait for the status window to finish, then close it if Microsoft says the update is complete.
3. Quit the app fully and open it again.
4. Sign out of Microsoft 365, then sign back in.
5. If the prompt returns, check whether the device is pinned to a different Microsoft 365 Apps update channel.

A common first-timer mistake is clicking Update Now, seeing a brief success message, and assuming the job is done. If the channel has changed through the update process, the app may still ask for another package on the next launch. That is a channel mismatch, not always a failed repair.

Check for blocked update delivery

1. Confirm the device has a working internet connection.
2. Try a different network if the current one is restrictive.
3. Restart the app after the connection is stable.
4. If the same loop continues on a managed device, ask IT whether Office CDN access is allowed.

Company device or managed install

If the PC belongs to an organization, the update behavior may be controlled by Group Policy, volume license settings, or a management tool such as Cloud Update, Intune, or Windows Autopatch. In that case, the user usually cannot override the channel or the update source from inside the app.

How to tell it is managed

• Update Options is missing even though Office opens normally.
• The account page shows signs of a volume license install.
• Updates recur on every launch across multiple Office apps.
• The device is owned by work or school.

What not to change locally

1. Do not keep reinstalling from a consumer download source if the device is managed.
2. Do not change channels unless IT tells you to.
3. Do not use Microsoft Update as a workaround if policy controls the install.
4. Send IT the exact app name, the channel name shown on the account page, and the exact message.

Microsoft Learn says channel changes are completed through the Microsoft 365 Apps update process. Microsoft also recommends Cloud Update for managing Microsoft 365 Apps, and Cloud Update uses the Office Content Delivery Network to download and apply updates. Devices must be in Inventory before Cloud Update can manage them. (Microsoft Learn)

Microsoft 365 update decision table

This table maps the symptom to the most likely cause, the owner of the fix, and the next step. Use it to avoid treating every update prompt as the same problem.

Apps will not open

If Office apps cannot open, repair Office before deeper reinstall steps. Microsoft suggests repairing Office when the update path is blocked by a broken install. This is the right next step when the prompt appears, but Word or Excel will not launch far enough to reach File > Account.

1. Save any open work in other apps and close all Office programs.
2. Open Settings > Apps > Installed apps.
3. Select Microsoft 365 or Microsoft Office, then choose Modify.
4. Run the repair option offered by Windows.
5. Open Word again and retry File > Account > Update Options > Update Now.

If that did not work

1. Repeat the repair once if the first pass was interrupted.
2. If the device is managed, stop and contact IT.
3. If the repair fails on a home PC, use the manual Office Updates path or reinstall Office.

Still not working?

At this point, check the internet connection again, verify that the account is signed in, and look for a stale channel assignment. If the app still loops, use the manual update download or escalate to IT. Managed devices often need a policy change, not another local click.

Escalation ladder

1. Confirm the device can reach the internet without a captive portal.
2. Restart the PC and open the app with the same account that owns Microsoft 365.
3. Check whether the channel in the account page matches the one IT expects.
4. Use the manual update package if Microsoft Update does not resolve it.
5. Contact IT for Group Policy, channel, or Inventory issues on managed devices.

Prevention is simple on managed fleets: keep the update channel aligned with the management tool, and avoid mixing consumer installs with company-controlled packages on the same device.

Frequently asked questions

Why won't Microsoft 365 update?

The app usually cannot reach the expected update source, or the device is controlled by policy. Start with File > Account and Update Options > Update Now. If that path is missing, try Microsoft Update or contact IT for a managed install.

How do I stop Microsoft 365 from updating?

Open File > Account and look for Disable Updates if the menu is available. If the device is company-managed, you may not be allowed to change that setting locally, and IT has to control the policy instead.

Do I need to update Microsoft 365?

Yes, if you want current fixes and compatibility. Use File > Account > Update Options > Update Now on a home install, or follow the company process on a managed device. If the app is broken, repair Office first.

Does Microsoft 365 update automatically?

Often it does, but the exact behavior depends on the channel and the device setup. A local app can pull updates from the Office CDN, while a managed device may receive them through Cloud Update, Intune, or Windows Autopatch.

What if Update options is missing in Microsoft 365?

That can point to a volume license install or Group Policy management. Use Microsoft Update if the device is not managed by IT. If it is a work PC, send the symptom to the help desk instead of forcing a local change.

Can I update Microsoft 365 manually?

Yes. If the normal path fails, Microsoft may offer a manual download from Office Updates. Close all Office apps first, run the package, and then reopen Word or Excel to confirm the version changed under File > Account.
