Teams Channel Disappear

[PDostiyar]

Hi all community members,

As we are doing different pilot group for our MS teams roll-out to whole organization currently we came across one issue that suddenly one of a Teams Channel Disappear from last two days we have around 18 users member of that Teams which had the default general channel and the other one "Pilot deployment" which is disapeard we have only two owners both didn't touch that part, also we checked Teams > Managed > Channels Under Active and deleted there is only general under active but nothing else.

though it had a planner tab which we created in that channel in the online planner we could see both the general channel planner and the Pilot deployment channel planner.

has anyone else came across same issue or concern.

Strange! And all 18 users cant see the channel anymore?

Check the audit log in the security and compliance center. There is a trigger for “deleted channel” and see if there is anything there!

we have checked all those part nothing found,

out of those 18 users only 2 were able to see the disappeard channel on their web browsers so using the web version as we have created a form survay to check with all the users.

when the owner created a test channel the channel which were missing from all others got disappeards from those two users web version as well and the new test channel created everyone can see it.

Try log out of teams app client and back in! Also try another browser or clear cache! It seems strange though affecting that many users! How about the mobile client?
If you still see inconsistencies For that many users I would create a ticket with Microsoft

[#5]

You are totally right we should go on creating ticket, the reason i posted here to get some idea or view if others had came across the same if not we will go to Microsoft route, 

since all these 18 users are technical and they are part of our Teams Roll-out project so we have done all the possible solutions from trying in to brand new computer, new Teams, new browser etc.

Ok! Keep us posted!!

You sure someone didn’t rename the test channel? Check the document library on the attached SharePoint site. Is the test channel name there?

I had this issue brought to my attention as well.  The Team Owner assured me they didn't delete the channel or rename it - it simply disappeared from the Channel list.  I confirmed that it does not show in the Deleted Channels list.  Also, I looked at the SharePoint site - and the folder does exist.  The team is comprised of 5 people (so it's easy to determine who may have deleted anything) and a total of 8 channels (so it's not as though it fell off from too many).  Also - we are only piloting Teams to this point - not a full, enterprise-wide rollout yet.  Fingers crossed this isn't a recurring issue.

I'm curious to know how many others are experiencing this problem

Yes this is something for sure i can say no one deleted it, as today one of the user was able to see using the web version it appeared to him in web version but nothing on desktop client of MS teams.

You are right we are also doing the Pilot before going to company wide roll-out though we are on the second pilot we have learnt alot in the first pilot and we may continue doing 2-3 more pilots with different departments.

And a log out / in wont relsolve the issue??

Dan, I would suggest checking the Audit Logs for this action as @adam deltinger mentioned, I've regularly seen users delete a whole team when trying to leave it, as apparently Delete Team and the Everything will be deleted messages really were 'not clear enough'.

Very occasionally the desktop client can get out of sync, particularly if you have unreliable network connections and typically signing fully out and back in refreshes is. Certainly not a regular thing in real life.

Thanks for your reply Steven that would be correct for Dan, but the case maybe different on our end since we have already open a ticket for this with Microsoft to see what will be the answer.

[#14]

It was good advice..........because guess what I found --> Lies and deceit! (or forgetfulness and embarrassment).  Thanks for the input!

Just as a new update there were 3 people inlcuding me, we were able to see the channel which was disappeard for a while one person was able to see in web only, i was able to see on my Iphone, and another person was able to see on the desktop client and so does on the web

[#16]

I have been experiencing this issue this morning. I have been trying to add new channels to my teams and they immediately disappear. It does not matter if I do it through the desktop app or the browser. 

[#17]

I'm having the exact same problem. 

[#18]

Having the same issue here. See my post in this post https://techcommunity.microsoft.com/t5/Microsoft-Teams/Creating-Channels-broken/m-p/357923#M27020

[#19]

Any new updates from your side on this and one question when you add more channels have your checked the followings?

The active and archives channels in settings?
Does the new channel creates libraries? You can checked it from online SharePoint site content section!

[#20]

Can you post a little more what exactly happens to your case?

Have you created new channels?
Have you checked the web, desktop, mobile version?
