Teams to Begin Automatically Hiding Inactive Channels

Prevent Inactive Channels from Cluttering User Views

In another step in Microsoftā€™s overhaul of Teams channels, message center notification MC804771 (24 June 2024, Microsoft 365 roadmap item 325780) announces the implementation of a new housekeeping function to clean up user channel lists by hiding unactive channels (Figure 1).

The change will only be effective in commercial and government tenants. Education tenants wonā€™t have their channels cleaned up. The update to the Teams 2.1 client for Windows, MacOS, and browsers will appear in mid-July for targeted release tenants and reach general availability for commercial tenants in mid-August 2024 with worldwide deployment scheduled to complete by mid-September. GCC, GCC High, and DoD tenants will see the update about a month later.

Channel clean up happens for both member and guest user accounts.

The Chaos of Inactive Channels

Tenants are well aware of the problem of digital rot caused by too many teams. Each team can now have up to 1,000 channels, and Microsoft is keen for customers to create channels rather than teams to reduce the amount of digital debris in their tenants. A shared or private channel can often replace a team, especially as both come with a dedicated SharePoint Online site to store documents.

It would be nice if those who created channels always maintained those channels, but this doesnā€™t happen in the real world. Like teams, channels can be created only become inactive or uninteresting to users quickly. It might be that the channel isnā€™t needed, that people discuss the topic created for the channel in a group chat instead, or that the topic simply isnā€™t worth a separate channel. For whatever reason, people lose interest and inactive channels find their way into user channel lists.

To solve the problem, Teams will automatically detect and hide inactive channels that users have not interacted with recently. Microsoft hasnā€™t said what period is used of inactivity Teams uses to make the determination or what interaction means. Based on experience with the preview version of the feature, interaction seems to mean open a channel to view conversations. Microsoft says that 45 days is the point used to decide if a user is active in a channel. It seems like Teams checks for inactive channels every couple of weeks.

When Teams detects inactive channels, it offers the chance for the user to review the set and make the call to unhide some of the channels (Figure 2).

Itā€™s a good idea to review the set of inactive channels selected by Teams because useful channels that are temporarily inactive will appear in the list.

Settings for Channel Cleanup

The Teams Settings app includes the ability for users to opt out of automatic channel cleanup as well as an option to initiate the cleanup process on demand (Figure 3).

If you opt to clean up now, Teams checks the current channel list and displays any that it believes to be inactive.

The important thing to remember is that a hidden channel is still available to a user and can be unhidden at any time by viewing the set of channels for a team and unhiding any that they want to see.

Inform Users About Channel Clean Up

Automatic clean up processes are usually a good idea and hiding inactive channels is an example of one thatā€™s worthwhile. However, like anything else that affects users, some explanation is necessary for people to understand why and what is happening. No one wants a bunch of help desk calls asking where a favorite (but inactive) channel has gone.


So much change, all the time. Itā€™s a challenge to stay abreast of all the updates Microsoft makes across the Microsoft 365 ecosystem.

  1. I am all for to hide some channels in my list. I am actually actively going and hiding some of them that are inactive or not relevant. But i wonder how are they going to do this. Some channels are not active for a while, but still important. I should see if new messages appear there. Will it automatically unhide them in such case. I am guessing that it will not. Which will be less useful and make some messages gone unseen.

    1. Re. channels are important – that’s why you get a chance to review them before Teams auto-hides. And if a channel is truly important, I guess people will go looking for it if it is hidden and be able to find it in the channel list.

  2. Hi Tony thanks for the info. Some colleagues reported that they cannot find some channels in Teams anymore and so I found your post:)

    I can experience the same behavior. We have lots of customer teams that get created from a MS Flow following a certain structure (5 general channels for each team). Lots of these channels are hidden now. I already unchecked the button in MS Teams saying:

    “Clean up channel list” but it seems like this is not reverting it. In some customer teams we have more than 100 channels for existing projects and the general channels such as “Basic Information” for example is at the very bottom and I would need to manually make it visible. This is obviously now acceptable.

    Does anyone know:

    Is there a way to globally deactivate that feature via MS Teams Admin and/or Intune to prevent newly registered devices / teams from cleaning up the channel list? Could not find anything so far.

    How can I revert these changes on existing devices so that it was like it was before (the general channels are on the top again).

    Thanks!!

  3. Can anyone confirm whether or not if a channel becomes active again once Microsoft has hidden it, will users receive notifications of the recent activity or will the channel become active again?

      1. FWIW, i have seen angry comment on MS blog that it doesn’t unhide channel and users are missing messages in such channel that was deemed inactive for them as they are not actively opening it.
