Office 365 Channel Mismatch

Last Updated On: 27 Sep 2026|

Problem

The Microsoft 365 Apps update channel detected on a managed computer does not match the channel required by your organization.

Cause

Changing the channel configuration alone does not immediately change the installed Microsoft 365 build. The new channel is reflected only after Microsoft 365 installs a build published for that channel.

Resolution

Use the Microsoft Office Deployment Tool (ODT) to change the update channel, and then update Microsoft 365 Apps.

Create the channel configuration

  1. Download and extract the Microsoft Office Deployment Tool to obtain setup.exe.
  2. Create a file named updateChannel.xml in the same folder.
  3. Add the following configuration and replace Current with the required channel value:
<Configuration>
  <Updates Channel="Current" />
  <Display Level="None" AcceptEULA="TRUE" />
</Configuration>

Supported channel values for this configuration are Current, MonthlyEnterprise, SemiAnnual, and SemiAnnualPreview.

Deploy the configuration

  1. Compress setup.exe and updateChannel.xml into a ZIP file.
  2. Create a software package using the ZIP file.
  3. Set the installation command to setup.exe /configure updateChannel.xml.
  4. Deploy the package to the affected computers.

Install a build from the new channel

The channel switch takes effect after a Microsoft 365 build from the selected channel is installed. After deploying the configuration, use either of these methods:

  • Scan the computer and deploy the next applicable Microsoft 365 patch from Vulnerability Manager Plus.
  • Open a Microsoft 365 application and select Account → Office Updates → Update Options → Update Now.

Verify the Update Channel

  1. Wait for the Microsoft 365 update to complete.
  2. Run a patch scan on the computer.
  3. Confirm that the detected Microsoft 365 update channel matches the channel selected in updateChannel.xml.
