Join the program

Insiders are passionate people who love Microsoft 365 apps, want to try out new features first, and make a difference in the products they use every day by providing early feedback. Ready to onboard? Go to the Join section of our site and choose your favorite platform (or platforms!) to get started.

Insider levels

The Microsoft 365 Insider program has two channels: Beta Channel and Current Channel (Preview). These channels determine how often, and how early, you get updates. Pick the one that’s right for you. Either way, we’re here to help and listen.

Beta Channel

We recommend this channel for people who want to try out new features while they’re still in active development, identify issues, and provide feedback. You will receive frequent updates that include new features as well as bug fixes and other updates.

Beta Channel is best suited for people who don’t mind the bit of risk involved in using unsupported builds.

Current Channel (Preview)

We recommend this channel for customers who want to receive supported builds with less frequent, more stable updates and minimal risk.

New features are released about once per month and may include bug fixes and other updates.

Note: For iOS, there is only one Insider level: Beta Channel.


Supported operating systems

Microsoft 365 Insider builds are available for the following operating systems:

  • Windows
  • Mac
  • iOS

You’ll need to be running a version of the operating system that is supported by Microsoft 365. For information, see the System requirements for Microsoft 365 and System requirements for Microsoft 365 mobile apps. We recommend that you run the most current version of your operating system.

Try new features

When builds are released, they usually include new features for you to try out. For a list of the features and updates that were included in a build, check the Release Notes on To learn more about features as they start rolling out to Insiders, visit the Microsoft 365 Insider blog on this site.

Why don’t I have a feature that’s mentioned in the Release Notes or Blog?

There are a few reasons why you may not see a new feature that you’ve read about.

  • Do you have an active Microsoft 365 subscription on your device? Most new features are only available to Microsoft 365 subscribers. If you are using a perpetual version of Office (i.e. 2016, 2019, LTSC), you won’t receive preview features.
  • Check for updates. You may not have the latest build on your device. Compare the build number from a Microsoft 365 app on your device to the latest build listed in the Release Notes.
    • Build numbers always go up with each new build. If the build number in your Microsoft 365 app doesn’t match the build number in the Release Notes or Insider blog, as long as your build number is higher than the one listed, your device will receive the feature when it is enabled. See “Features are rolled out in stages,” below.
    • For details on how to find Microsoft 365 build information on your device, refer to the What information should I have available when asking for help? section in the Get Support topic on this page.
  • Turn on the Coming Soon toggle. If you have the latest Microsoft 365 build installed, check for a “Coming Soon” toggle in the upper right corner of the app. If you see one, make sure that it is toggled on, as some new features will only appear when it is in the On position. Please note that this toggle does not always appear, and this is normal.
  • Features are rolled out in stages. Features in a specific build are exposed in stages to progressively larger groups of Insiders over time. If you are unsure whether this is the case, or if you have any other questions about accessing or using a new feature, please reach out to us on X (formerly Twitter) @MSFT365Insider or in the Micrososft Support Community forum.

Provide feedback

We’d love to hear your thoughts about what works, what doesn’t, and how we can improve.

Within a Microsoft 365 App

The quickest way to get your comments to our engineers’ ears is right from within Microsoft 365 apps. They read customer feedback daily.

  • From your Microsoft 365 app, go to Help > Feedback (or FileFeedback).

  1. Select Help > Feedback.

    Select Give Feedback in Mac OS

  2. In the Send feedback to Microsoft dialog box, choose the type of feedback you want to provide.

    Feedback dialog for Mac OS

  • From your Microsoft 365 app, select “” in the top right corner and then select Help & Give Feedback.
  • Open a Microsoft 365 app, tap your username in the top right corner of the app window, and select Settings > Send Feedback.

On the Feedback portal

On the Microsoft Feedback portal, you can browse for and submit feedback, upvote feedback from the community, and see status information from Microsoft.

In an Insider community

Be a part of our community and interact with fellow Insiders by posting to the Microsoft 365 Insider Answers forum or the Microsoft 365 Insider Tech Community. You can also tweet us @MSFT365Insider.

What kind of feedback is best?

Detailed and actionable feedback is vital for making changes and improvements to our apps. If you find a bug, have an issue, or have a great suggestion for how we can improve, we’d like to hear it. Here are a few tips that will help us categorize and share your feedback with the right people.

  • Use a concise and descriptive title
    Descriptive and specific titles help engineers understand the issue being reported. An example of a good title: “Excel’s ‘recent files’ list does not include recently added OneDrive files.”
  • Focus on one issue at a time
    Providing feedback one item at a time ensures the correct logs and data are received with each submission and can be assigned to someone for follow up. Also, it helps us identify the volume of feedback we’re receiving on a particular issue.
  • Write details in the Description box
    Information about your device, operating system, and apps are automatically reported when you submit feedback from an app. But detailed steps to reproduce the issue and screenshots (if applicable) are very helpful when you provide them.


Get support

Beta Channel

These builds are unsupported, but we encourage you to report issues and provide feedback from within the app.

Note: If you encounter an issue that is impacting your productivity, try changing to a supported channel, such as Current Channel (Preview) or Production.

Current Channel (Preview)

The most recent build is fully supported, so you can contact one of our experts at Microsoft Support if you need help.

Other ways to get help

What information should I have when asking for help?

When contacting us on X (formerly Twitter) or when posting in the Microsoft 365 Insider Community Support forum, please provide as much of this information up front as possible. The more details you can provide, the easier it will be to help troubleshoot the issue and determine the right solution. Here are some details to keep handy:

Step 1: Find the version/build for your platform:

Platform How to find your version/build
  1. Open a Microsoft 365 app and navigate to File > Account.
  2. Look for the About tab on the page and find the line that says “Version xxxx (Build xxxxx.xxxxx)”.
  3. If you are unable to launch a Microsoft 365 app, or the app closes or crashes before you can get to the Account screen:
    1. In Windows Settings, choose Apps > Installed Apps.
    2. In the search box, type 365 and press Enter.
    3. You should see the Microsoft 365 version number, which looks like this: 16.0.xxxxx.xxxxx.
  1. Open any Microsoft 365 app (such as Word), then navigate to the Word > About Word menu (or equivalent in any other app.).
  2. On the About window that opens, look for the line that reads “Version 16.XX (Build XXXXXXXX)“.
  1. Launch the TestFlight app, then select a Microsoft 365 app.
  2. The version number is listed under the app name, formatted as “Version 2.XX (Build XXXXXXXX)“.
  3. Be sure that you have installed the latest available version.
  1. Launch the Settings app, then tap Apps & Notifications.
  2. Find the Microsoft app you are looking for in the list of apps and tap on it.
  3. Scroll to the bottom of the app’s information screen and find the version number listed as “16.0.xxxxx.xxxxx”.


Step 2: Provide as much detail about the issue as possible:

  • Is there an error code or message? Make sure to provide the whole error code or message, or a screenshot of them.
  • Does this happen with all files in the app, or only with specific files?
  • Where is the file saved? On your local device, in the cloud (on OneDrive, or another cloud service)?
  • Is there something unique or different about the impacted file(s)? Are you using a specific font, a VBA script, a macro, or a different language than usual?
  • Are you running any add-ins? Is the issue still present if you disable your add-ins?
  • What steps are needed to reproduce this issue?
    • If you need to change any settings, be sure to specify.
    • Here’s an example: “Launch Word. Open a new document. Type anything into the document. Highlight the text, right click on it, then select Font. The Font menu doesn’t pop up.”
  • Is this behavior new to the build you have now, or did it happen in previous builds as well?
