Office 365 - Registry question about Update Channel

David Moon 371 Reputation points


I have done a o365 channel change from Semi Annual to Monthly, using GPO and Intune policy. Simply policy to change from deferred to Monthly Enterprise.
So that triggers few changes to the workstations.
One of the change being to the registry key:
UpdateChannel =

However, CDNBaseUrl remains as "".

The channel update happens all works OK.

However, CDNBaseUrl still remains as "".

So my question is, does it matter if CDNBaseUrl value does not match UPDATECHANNEL value?

Thanks, DM.

    Hi @David Moon ,
    Welcome to Q&A forum!

    The following information comes from this official article: How to manage Office 365 ProPlus Channels for IT Pros, please check if it helps you.

    Q: I installed Office initially on one channel and later used GPO to assign a new one, is it normal for the CDNBaseURL and UpdateChannel not to match?
    A: It depends. If a GPO is used to change channel, values will not match. CDNBaseURL will reflect value when Office Deployment Tool (ODT) was run where Update Channel "winner" will reflect the GPO. If ODT was used to change change channel, ODT will directly change CDNBaseURL to value defined in Config.XML and if priority order above aligns, UpdateChannel value will match.

    Any updates, please let me know.
