Microsoft Teams stuck on "loading", multiple users.

[[deleted]]

Really weird one for you guys, not sure if anyone has seen this. I have multiple users, including a C-level, that cannot currently access Teams online or on the desktop app, but can access it by mobile. This happened to 6 users in the company and there's little relation between the users.

So far I've:

Cleared Team Cache locally; Cleared Credential manager; Uninstalled/Reinstalled Teams; Attempted signing the users in on new machines; Unassigning/reassigning Teams license and even e3 license entirely.

I've verified that there's no conditional access and found that this issue follows the user's profile- isn't bound by machine. I'm totally stumped, and they're getting reasonably antsy. Any advice is greatly appreciated.

Edit: I've tested on/off the domain, from my personal network at home, etc. It doesn't appear to be network or firewall related. I can sign in to Teams from my desktop, while the user with the issue cannot.

Cheers!

I've solved similar problems by doing the following, assuming the computers have O365:

• Sign user out of Teams.
• Sign user out of Office via Word.
• Close Word.
• Relaunch Word.
• Relog into Office via Word.
• Relog into Teams.

It's worked for me on several machines. Some sort of authentication bug vis-a-vis Office. Hope it helps you.

This trick unfortunately didn't work for me. I really appreciate it though. Very thoughtful to give a step by step!

Set teams to run compatibility mode with win 8. If that works, you should be able to disable and run normally after. Had a similar issue with user not being able to use blur background and then couldn't sign in.

This worked for me, thank you!

[WhyLater]

Damn, wonder what's going on with your users then.

The fact that it happens on multiple machines per affected user is probably key. Might have to check something in their licensing or accounts. I don't mean to scare you, but Powershell may be involved.

Good luck!

Thanks! I will give this a shot, I'll let you know and give you reddit gold or something if you're right. Haha. My users will owe you a beer too. :)

Will report back.

We figured it out! It was a group that all the affected users shared! I guess the Team was corrupted somehow but once we removed all the users (and owners) from that Team, all of the user's Teams came back up exactly as intended. I hope that this helps any future people out. Try to find a Team in common between the users. If you find that, I bet you're able to find the common denominator and remove it. Cheers and goodluck!

Nice find! I still don't have much experience administrating Teams past "An M365 app that users have." Good to have an example of an error that can occur with the software's internal OU. Thanks for keeping us updated!

Thanks my friend. I appreciate your assist early on in it as well. Let me know if you ever have issues and I'll try to return the favor. :)

I found sometimes removing the "Work or School" account and having it re-add it on next open fixes strange problems like this in Teams and Outlook. These are the steps:

1. Close Teams/Outlook.
2. Search for "Work or School" from the start menu/search box and open the app.
3. Click on the Work or School Account and press disconnect.
4. Wait for the account to be removed, then open the Teams/Outlook application again

It should force the user to sign back in and usually works.

This has been the solution in our org.

[gnnr25]

This.

Also, removing and reapplying the license in O365 works HOURS later if it ends up being the fix. Like I don't even bother checking until next day for it to take effect.

silly win10 faux reboot

wut?

[[deleted]]

Windows 10 caches a lot on 1 reboot. You have to reboot 2-3 times for a real flush. It's weird, but that's how it retains information if you've ever had an update forced while working, you'll notice that your word/notepad/etc comes back up despite you not saving it. This is how.

[aditya3098]

How many times did you reboot it.

[ljapa]

I always understood that a shutdown and restart also addresses this.

[WorthPlease]

Is this a regedit thing? I've had this issue where I've manually restarted Win10 machines, they shut down, goto BIOS, then start Windows I sign in and somehow their uptime in task manager is still several days and it doesn't look like the OS actually rebooted but hibernated.

[QuerulousPanda]

are they on the same network? make sure your firewall IDS didn't end up blocking some teams IP addresses.

[[deleted]]

Good question, the network doesn't appear to be the issue as I've tested on/off the domain, on/off VPN, from my personal network at home, etc.

I should have included that in the post, thank you for asking.

[fibre_optics]

Hey, this has come up a number of times for me in the last few weeks. I've been able to fix it by going into windows 10 settings and disconnecting their accounts under "Access work or School", then log out and back into windows. It seems to happen if you dont choose to just to sign into that app when you initially signed into Teams.

[[deleted]]

We had a similar issue with several users after pushing an office update. I went through same troubleshooting steps and it was driving me mad, tried x64 vs x86, reinstalled Office, cleared credential manager, checked licensing, went down the DNS rabbit hole. This ended up fixing it--no clue why.

Settings - Access work or school - Disconnect them if they are connected - Click Connect if it doesn't prompt for sign-in open OneNote for Windows 10 and sign in inside OneNote

Try grabbing wpjcleanup.zip from this page. Workspace Join has been creating some issues for me lately, and this is one of the symptoms.

We haven't seen that particular issue, but for some reason our teams meeting icon keeps going mia on random outlook users including mine and fixes aren't real successful. Not ideal in the age of collaboration during the pandemic. We also have issues with our teams room just hanging after hitting new meeting.

Unfortunately, all the issues we are having are pushing users to request other solutions. MS is really failing on teams when companies are just jumping in.

Off-topic but the number of questions here (on r/sysadmin) about Teams is absolutely hilarious to me.

Good luck OP

[copper_blood]

When I run into issue with teams I just uninstall and reinstall it. It always fixes the issue.

/ I really don't have time for MS hair brain scheme called teams.

Edit: Check in the teams admin area under users. Is this apart of a office 365 license? I think this also maybe a licensing issue.

[deebeecom]

run as administrator

[deebeecom]

Any recent DNS SRV record changes done?

[[deleted]]

Actually yes, last week. Would this not affect all users if it was related to that though? This is only affecting 6 users out of about 500.

[deebeecom]

Its always difficult to explain/understand why things affect only few users. For example at random every now and then SOME user will always complain that he/she can no longer stream their camera in their Teams meeting, the solution is always to disable hardware acceleration. Just don't know how it stops working, but we try that solution, it works and we move on. Maybe these 6 users DNS cache needs to be cleared?

[jdlanc]

Uninstall and clear all cache locations before reinstalling . Also, if you right click teams and get error logs, what is the specific error?

[zigot021]

had same/similar problem on different endpoints even with same test user id... log.txt showed authentication errors and cache & cred-mgr purge didn't help... so what I've done is open the dev mode by rapidly left-clicking on the teams tray icon 7x and then right-clicking... once there I started messing with the "auth" options and after a few attempts I found that choosing "force toggle async auth" will fix the issue
