Microsoft Teams Trello Login not working
Asked by Laurent:

I'm trying to login to Trello through the Microsoft Teams plugin. I login with my credentials without any credentials error, but I get constantly get forwarded to a login/signup page. Is this a cookie issue or what?

Also, in some cases I get to a page in the login plugin that says in bare html "first you need to log in"

body: In 2022, still the same problem...  
Would like to use Trello with my team, but still no solution available?  
Think we might switch to some other platform, then...

Delete your Atlassian account that uses your Microsoft 365 log-in. That's if you're already using Trello before you were using 365.

Then log in to Trello in Teams using your previous (non-Microsoft 365 account) credentials. Confusion resolved/deleted.

Bingo!

It worked, thanks.

body: Having the same problem.

I can view Trello fine in browser

I can view Trello fine through Trello desktop app

I can view Trello fine from MS Teams in a Browser

...but I can't view the Trello tab on a Teams channel using the MS Teams desktop app.

I click login and the pop up window is blank.

body: Was this ever resolved?


author: Phil
body: Hi All

I have a similar issue. Trello in Teams says 'switch account'. I try to and nothing happens, I also try logging out and it still doesn't work.

I've found there's a clash between Atlassian log-in and my Microsoft 365 log-in.

Atlassian doesn't recognise my Microsoft 365 log-in for Trello and therefore asks me to log-in....to no avail.

A serious fix needs to happen rather quickly on this!

All was well before Atlassian bought / took over Trello.....

author: Richard Swallow
body: May 15th - same issue. I just get the Trello About window which shows me logged in but I cannot click save as it is greyed out - so i can't create any boards. Bloody useless.


author: Richard Swallow
body: Figured it out - I was logged into Trello via my browser, of which I had 7 tabs open so it was 'hidden'. I did this whilst joining in Teams and then searching for a resolve for not connecting in Teams. When I logged out of Trello via the browser I was able to log into Trello inside Teams. so basically, you can't log into same account at the same time - twice.


author: Matthijs
body: Having the exact same issue here. Tried login out on web app, deleted the application and downloaded it again. No success. Hope they will fix it soon. Strange thing is, my colleagues do not have any issue at all...

comments: author: KT
body: It's similar here, being that some can access and others can't.


author: Sofia Schramm
body: Hi there, I have the same issue. I have tried everything that I can think of, but to no avail.

It would be great if someone could look into this as it is driving all of us crazy.


author: KT
body: We are having the same issue today with Trello and Teams. It seems to only be the Teams Desktop application that is affected, Web App works fine.

comments: author: KT
body: FYI I've created a support ticket with Trello regarding the issue, will post the results back here as and when.


author: Brander, Matt
body: Thanks Liam. Same issue here


author: Auret Van Zyl
body: Exact same issue, started today after working perfectly fine. It works in Web App but not the desktop application. I even did a hard reset on my computer, IE: format and reload and it's still not working and doing the exact same thing.

comments: author: Dan Moran
body: Must be SSO issue or Credentials Manager but cleared everything. Bug I assume.


author: Dan Moran
body: Seems to be linked to the TEAMS desktop app. If you open the web app trello works fine. I have removed Teams and reinstalled still no joy. tried a different profile and still same error. So something must reside on the machine after uninstall that is causing this issue. I have removed all credentials in Manager. Still no joy. Must be the SSO setting but where is it stored ?
