Team disappears from the side rail if a channel is in the section
That behavior doesn’t match Microsoft’s documented custom-section model: moving one channel should organize that conversation, while other shown channels remain under Teams and channels. The documented case that hides a team is when all of its channels are hidden.
I’d first clear Unread and any Channels filters. Then select See all your teams, open the affected team, choose See all channels, and select Show for at least one channel other than the one in Favorites. Also check Teams and channels > More options > List options and try a different sort order.
If the team still disappears, switch Customize view from Combined to Separate and back, update Teams, and compare the desktop client with Teams on the web. If web works, this is likely a desktop client-state issue; if both behave the same way, capture the Teams version and screenshots and have your Microsoft 365 admin open a support case. I wouldn’t treat the three-click route as intended without confirmation from Microsoft. Does showing a second channel restore the team?
It behaves the same in the web version. Teams is up to date. I don't use any filters at the top. It is the same with Combined and Separate mode.
I just tested this again in the web version. After this issue started i have decided to get rid of my setup with sections (thanks Microsoft, now even less people use them). So i have removed all channels from my Favorites section and deleted it. Then all my teams started to show again in the side rail. A minute ago i have added one channel to a new section called Test. This team and all channels were still showing. Just when i selected Unread in the section settings, immediately whole team disappeared from the side rail.
So, if you decide that section should only show unread things. And even if you add only one channel out of many from the team into such section, then Teams thinks it should hide the whole team from the UI. It feels like a bug, although i will not be surprised this is by design somehow. As it aligned with Communities being added to the side rail, i am guessing they behave differently and it somehow affected old behavior with channels and sections.
