Teams desktop app: Teams and Channels disappearing

Question

Teams desktop app: Teams and Channels disappearing

Vlada 0

Hello,

I am a member of 20 Teams teams, but some of them keep disappearing from the Teams section in the desktop application, even after I click on “See all your teams.” It is impossible to find the missing teams using the Search function.

However, when I open Teams on the web, all 20 teams are listed.

Interestingly, when I perform some actions in a missing team using Teams on the web, like opening a file or checking the activity, the team appears in my desktop app within a few minutes. Also, if someone tags me in one of the missing teams, it appears there as well. However, this is extremely inconvenient for my daily work routine.

I have tried repairing and resetting Teams. I have also logged out and back in several times. However, the problem keeps coming back.

Is this an issue with the Teams desktop app? How can I resolve it?

Thank you in advance.

I have user with a similar issue. Been happening the last several weeks. Going to Settings -> Apps -> Teams -> Advanced Options, and used the Repair button nothing is fixed. Reset will get them back for a day maybe two. The web version of Teams always works. I have tried completely removing the teams app and re-installing and it continues to happen.

Hi Alina, I tried the fix you advised a few times in the past, it helps but after some time, like a few days of a week, the problem comes back just as @Joshua Nye says.

Hi @Vlada

Thank you for your update!

Many users have experienced that the Teams desktop app does not consistently display all Teams or Channels, while everything appears correctly on Teams Web. In many cases, a missing Team only shows up again after new activity occurs such as someone tagging you or you opening a file in that Team. This behavior indicates a synchronization delay combined with cache inconsistency.

I have reviewed the situation again and can confirm that this issue happens randomly for multiple users, and at the moment there is still no permanent fix available.

However, based on users feedback, switching to the "Seperated view" has helped improve the issue for some people. You may try enabling this view to see if it works better with your interface.

Open Microsoft Teams (new version).

Click on the “…” (More options) in the left navigation bar or top-right corner.

Select “Customize View” or go to Settings.

Under View options, choose “Separate” instead of Combined View.

Teams will switch to the classic layout, where Chats and Teams/Channels are displayed separately

Finally, to ensure everything remains up to date in the meantime, you can temporarily use Teams Web, where content is usually synchronized more reliably.

Answer 2

This behavior is typically caused by how Teams shows, hides, and organizes teams and channels in the desktop client rather than by a loss of membership.

In the current Teams experience, some teams can be automatically moved to Hidden teams if they have not been visited for a while. Those teams still exist and still receive activity, but they no longer appear in the main Teams list until they are explicitly shown again.

To check and correct this in the desktop app:

Go to the Teams view.
Scroll to the bottom of the list and look for Hidden teams.
Expand Hidden teams and locate the missing teams.
For each missing team, hover over the team name, select More options …, then select Show to move it back into the visible list.

If the issue is that specific channels within a team are missing rather than whole teams:

At the bottom of the chats and channels list, select See all your teams and channels (or See all your teams).
Select the relevant team.
Next to any channel that should be visible, select Show.

Notes:

Hiding all channels in a team also hides the team from the main list; showing at least one channel brings the team back.
Hidden channels and teams still receive notifications for @mentions, tags, and followed threads, which matches the behavior described (they reappear after activity).

After explicitly showing the teams/channels that should always be visible, the desktop app should keep them in the main list and align more closely with what is seen in Teams on the web.
