Unlike Microsoft 365 for Home, I can’t seem to switch between the Office Insider release builds via File-> Office Account-> Office Insider when using Microsoft 365 Apps for Business. Instead, I need to use custom installers to achieve this. As I test the various Office release channels, I prefer not to reinstall but to simply update; Go from the oldest release channel and switch to a newer each time. Is there any way to still be able to switch between Microsoft 365 Apps for Business channel releases by using Group Policy or editing the Registry?

By default, within Microsoft 365 Apps for Business and Enterprise, you indeed can’t change between the Office Insider levels from within an Office application as you can with Microsoft 365 for Home.

The main reason for this, is because the Office Insider Beta Channel (previously known as Office Insider Fast) is not a supported build of Office and that is not a state to be in as a company.

However, if you have a specific need to test out the Beta Channel release as a business or enterprise user, Microsoft offers the following methods;

Registry or Group Policy setting: Show the option for Office Insider

This will reveal the Office Insider button just like in Microsoft 365 for Home.

Useful when you need to switch between Channels or want to give the user control over which Channel they use.

This will reveal the Office Insider button just like in Microsoft 365 for Home. Useful when you need to switch between Channels or want to give the user control over which Channel they use. Registry or Group Policy setting: Update Channel

Useful when you don’t regularly change between Channels and don’t want to create custom installers.

Useful when you don’t regularly change between Channels and don’t want to create custom installers. Create custom installers to switch to Office Insider builds.

Useful for larger deployments and when you need to make additional changes such as which Office applications are installed and which language packs.

The Group Policy and Registry methods are detailed below.

Note: These methods can also be used to quickly switch over a certain user when you want to deploy a certain fix that he or she really needs but is not yet available in your default/corporate release channel.

Method 1: Group Policy setting: Show the option for Office Insider

When you have Microsoft 365 Apps for Business or Enterprise installed on a Professional or Enterprise edition of Windows, then you can use a (local) Group Policy to enable the Office Insider button in the File-> Office Account section.

Once you’ve added the Administrative Template files (ADMX/ADML) for Microsoft 365 Apps for enterprise, Office 2019, and Office 2016 to you computer’s PolicyDefinitions folder you can set the following policy;

Local Computer Policy-> User Configuration-> Administrative Templates-> Microsoft Office 2016-> Miscellaneous-> Show the option for Office Insider



Enabling the Office Insider button for Microsoft 365 Apps for Business and Enterprise.

Note: When enabling this policy, make sure the Update Channel and Update Path policies aren’t enabled or the Office Insider button will show but the selected Insider settings will not apply.

Simply set the preferred value in the Group Policy editor and then close all your Office applications and wait a few minutes.

Now when you open an Office application and go to File-> Office Account, you’ll see the Office Insider button with the Change Level command to set your preferred Office Insider Channel but also to disable it and go back to the Office Channel that was assigned to you.

After switching Office Insider settings, make sure you choose Update Options-> Update Now to switch to the correct Channel.

Method 2: Registry: InsidersLabBehavior

If you can’t set Group Policies, you can achieve the same results as method 1 by setting (or creating) the InsidersLabBehavior Registry value on your computer.

Key: HKEY_CURRENT_USER\Software\Policies\Microsoft\office\16.0\common

Value name: insiderslabbehavior

Value type: REG_DWORD

Value: 1

After implementing the Registry value, the same instructions as for the Group Policy method apply to update or downgrade your Microsoft 365 Apps installation.

Method 3: Group Policy setting: Update Channel

When you have Microsoft 365 Apps for Business or Enterprise installed on a Professional or Enterprise edition of Windows, then you can use a (local) Group Policy to switch between the release channels including the Beta Channel.

Once you’ve added the Administrative Template files (ADMX/ADML) for Microsoft 365 Apps for enterprise, Office 2019, and Office 2016 to you computer’s PolicyDefinitions folder you can set the following policy;

Local Computer Policy-> Computer Configuration-> Administrative Templates-> Microsoft Office 2016 (Machine)-> Updates-> Update Channel



Setting your Office 365 channel release via a local Group Policy.

Valid values, from the newest channel release to the oldest build, with their corresponding update channel name are;

InsiderFast

Beta Channel

(aka: Office Insider Fast)

Beta Channel (aka: Office Insider Fast) FirstReleaseCurrent

Current Channel (Preview)

(aka: First Release for Current Channel or Office Insider Slow)

Current Channel (Preview) (aka: First Release for Current Channel or Office Insider Slow) MonthlyEnterprise

Monthly Enterprise

Monthly Enterprise Current

Current Channel

Current Channel FirstReleaseDeferred

Semi-Annual Enterprise Channel (Preview)

Semi-Annual Enterprise Channel (Preview) Deferred

Semi-Annual Enterprise Channel

Simply set the preferred value in the Group Policy editor and then close all your Office applications and wait a few minutes.

Now when you open an Office application and go to File-> Office Account-> Update Options-> Update Now, it will update (or downgrade) your Office installation to the latest version of that release channel.

Note: Your Microsoft 365 administrator must have enrolled you in the proper release channel for some builds to be available to you. However, if the Microsoft 365 Apps Current Channel (Preview) release is available to you, the Beta Channel (Office Insider Fast) release is available to you as well.

Method 4: Registry: Updatebranch

If you can’t set Group Policies, you can achieve the same results as method 3 by setting (or creating) the Updatebranch Registry value on your computer.

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\office\16.0\common\officeupdate

Value name: updatebranch

Value type: REG_SZ

Just like the Group Policy values, you can set the following strings (from newest release channel to the oldest build);

InsiderFast

FirstReleaseCurrent

Current

MonthlyEnterprise

FirstReleaseDeferred

Deferred
