Running Automatic and Manual Office 365 Updates

Office 365 is a set of cloud-based services including popular applications such as Word, Excel, PowerPoint, and Outlook. All Office 365 applications can be used in a web browser. But Word, Excel, PowerPoint, Outlook, and OneNote are traditional applications that you can install on a computer running Windows or macOS. When using the web versions of Office 365 apps, you’re always using the latest versions with the latest features. Stand-alone versions of Office 365 apps provide more convenience and performance when editing documents, but you may need to check for updates. Software vulnerabilities can be found in any application, and Office 365 is no exception.

Vulnerabilities can be used by malicious actors to initiate malware or ransomware attacks on your computers. Microsoft regularly fixes new-found vulnerabilities and includes them in Office 365 software updates. That’s why you are more protected if you use Office 365 software that is up-to-date. This blog post covers Office 365 update settings and explains how you can change these settings by using different methods.

Update Options in Office 365 Applications

How to update Office 365? Let’s look at how to update Microsoft Office 365 applications installed on a computer by using the update options in these applications. You need to have stand-alone applications from the Office 365 suite installed on your computer and an Office 365 subscription. Make sure the subscription plan you use includes stand-alone Office applications. Log in to Office 365 in one of the applications by using an active account with the assigned license.

  1. Open one of the Office 365 applications installed on your computer, for example, Microsoft Word 365.
  2. In the menu bar of the Word window, click File.How to check for Office updates in Word 365
    The File menu opens.
  3. Click Account (More > Account).How to check for Office updates in the Account page of Word
  4. The Account screen opens. We have already logged in to Office 365. In the Office Updates section, click Update Options. In the menu that opens, you get four options:
  • Update Now – this is the option to update Microsoft Office right now.
  • Disable Updates – use this option if you want to turn off Office updates.
  • View Updates – this option opens a Microsoft web page with the information about Microsoft 365 updates and each version. You can check software changes compared to the previous version.

  1. To start the update process, click Update Now.How do I update Microsoft Office
  2. First, Office 365 needs to check for Office updates. If there are available Microsoft 365 updates, then the updates are downloaded and installed. You should see four steps during updating Microsoft Office 365:
  • Checking for updates – Office 365 software connects to Microsoft servers to check for updates.
  • Downloading Office updates – Microsoft Office updates are downloaded to the computer.
  • Save your work before continuing – opened Microsoft Office 365 applications must be closed to continue and install updates. Save changes to open files if necessary and click Continue. Office 365 applications are closed after you click Continue.
  • Applying updates – downloaded Office 365 updates are being installed on the computer.
  1. The appropriate window is displayed at each step while updating Microsoft Office 365.Updating Microsoft Office
  2. Once the Microsoft 365 update is finished, you should have the latest version of Office 365 available on your computer. Now you can reopen the Office 365 applications.

Update Channels

One of the Office 365 features is that installed Office applications such as Word, Excel, and PowerPoint are updated more frequently compared to traditional Microsoft Office 2019, 2016, etc. Microsoft provides several update channels for customers. The update frequency depends on the selected update channel. Thus, you can control how often updates should be installed by selecting the update channel. Let’s look at the most used update channels.

Semi-Annual Channel. Security updates are provided once per month. Non-security updates are provided twice per year. New features are released in January and July. Features included in the Semi-Annual Channel were previously released in the Monthly Channel. This channel is the default Office 365 update option for Office 365 Pro Plus and is generally the basic option. Other names for this channel are “Broad” and “Deferred”. Use this channel if you want to keep the oldest supported build longer and avoid frequent major updates.

Semi-Annual Channel (Targeted). This update channel is similar to the Semi-Annual Channel, but new features are released four months earlier – in March and September. Security and non-security updates are delivered monthly. This channel is positioned as the testing channel because new features are available earlier.

Monthly Channel. The newest features are provided as soon as they become available. Security and non-security updates are delivered monthly. The Monthly Channel (also known as the Current Channel) is the default option for Office 365 Business subscription plans (such as Office 365 Business Premium).

Monthly Channel (Targeted). This update channel is similar to the Monthly Channel but updates are released about a week in advance. This channel was formerly known as the “Insiders” build and now is known as the “Current Channel Preview” build.

  2. Click File > Account and locate the About Word section.
  3. The version number, build number, and update channel name are displayed in this section. In our example, we have Office 365 version 2108, build 14326.20404. The Current Channel is used to deliver Office 365 updates.Office 365 latest version

Methods to Edit Update Channel Options

There are multiple methods to change an Office 365 update channel. Office 365 must be already installed when you use the second, third, and fourth options:

  • Using settings in the Office 365 admin center
  • Using the command prompt on a Windows machine where Office 365 applications are installed
  • Editing registry settings in Windows
  • Editing a group policy in Windows
  • Using the Office Deployment tool with a custom configuration

Note: When you move from a channel with a higher Office 365 build number (for example, Current Channel) to a channel with a lower build number (such as Semi-Annual Channel), the update (the amount of downloaded data) can be larger than usual. Features available only in the newer version are removed in this case.

Channel options in the Office 365 admin center

Using Group Policy Editor

In Task Scheduler, make sure that the Office Automatic Updates 2.0 task is enabled. This task is required to run automatic updates for Office 365. The task detects changes in the policy and updates the selected channel in the configuration.

  1. To open Windows Task Scheduler, click Win+R, type taskschd.msc, and click Enter. As an alternative, you can find the appropriate shortcut in the Start menu or Control Panel.
  2. Go to Task Scheduler Library > Microsoft > Office and find Office Automatic Updates 2.0.
  3. In our example, everything is OK, the task is present. We can now configure a group policy for selecting a channel for Office 365 updates.Checking the task to check Microsoft Office updates in Windows Scheduler
  4. To open Windows Group Policy Editor, click Win+R, type gpedit.msc in the Run window, and click Enter.
  5. The needed administrative template is missing. There is no Microsoft Office folder that contains the needed policies in the Administrative Templates folder. For this reason, we need to add the required administrative template to edit Office 365 update group policies.The needed Office 365 administrative template is missing in Group Policy Editor
  6. You can close Group Policy Editor for now while you add the missing administrative templates.
  7. Download administrative template files for Office 365 by using this link:
    Depending on the version of Office 365 installed on your Windows computer, select the 32-bit or 64-bit version. We use the 64-bit version.
  8. Run the downloaded file:
  9. Define the directory to which files should be extracted, for example, C:\temp\o365+\
  10. ADMX files are extracted to the selected directory. ADMX files are Windows administrative template files used to configure settings by changing registry entries. ADMX files are XML-based files that can be created and edited in an editor that supports the XML format.Note: The ADM extension changed to ADMX starting from Windows Vista and Windows Server 2008.
  11. Check the admx subdirectory in the directory to which you have extracted the files (C:\temp\o365+\admx in our case). There are subdirectories for different languages. We use English and also need files in the en-us directory.Extracting admx files to configure Office 365 administrative templates
  12. Windows administrative template files (ADMX files) are stored in C:\Windows\PolicyDefinitions\ where C:\Windows\ is the default Windows installation directory. This path can be defined as %systemroot%\PolicyDefinitions\ for any name of the directory in which Windows is installed.Location of administrative templates in the Windows system folder
  13. In order to add administrative templates, you should copy the appropriate ADMX files to %systemroot%\PolicyDefinitions\, which is a system folder.In the screenshot below, you can see the contents of C:\Windows\PolicyDefinitions\. We copy the extracted files from C:\temp\o365+\admx\ and C:\temp\o365+\admx\en-us\ to C:\Windows\PolicyDefinitions\ and C:\Windows\PolicyDefinitions\en-us\ accordingly.
  14. Run gpedit.msc and open Windows Group Policy Editor once again.
    Now the needed templates are available.
  15. Go to Computer Configuration\Administrative Templates\Microsoft Office 2016 (Machine)\Updates.
  16. Double-click the Update Channel setting.Opening Office 365 administrative templates in Group Policy Editor

By default, a policy should update automatically every 90 minutes. The Office Automatic Update 2.0 task should run after you update the policy and run gpupdate for the changes to take effect.

Using the Office Deployment Tool

Using the Office Deployment Tool was explained in the blog post about Office 365 ProPlus and remote desktop configuration. The tool is used to start Office 365 installation with custom parameters. In order to define the Office 365 update channel, download and extract the tool. Then edit or add the following section to the xml configuration file:


<Updates Channel=”MonthlyEnterprise” />


Define the Office 365 update channel such as:

<Updates Channel=”Current” />


<Updates Channel=” Channel=”Deferred” />

You can define any supported update channel. Save the XML configuration file and deploy Office 365.

Office 365 update channel configuration set in the group policy (explained in the previous section) has higher precedence than the configuration for the Office Deployment Tool. Make sure that the update channel is not set in the group policy to configure the update channel with the Office Deployment Tool.


Office 365 updates allow you to have up-to-date applications with bug fixes and new features. You can tune the update options depending on your needs and set the frequency of receiving the updates. Different Office 365 update channels are used for this purpose. Multiple methods can be used to define the update channel. Office 365 updates fix security vulnerabilities that can be considered as a potential threat to your data.
