Trello connector on Microsoft doesnt work

[André Johst]

Hi there, I m currently struggling with getting my trello connector on microsoft running. 
It doesnt find User or Elements on my admin center. 
I had multiple calls with the microsoft team but they say on their end everything is set correctly. 

Does anyone have a clue or has faced similar issues?

Thank you in advance for any help

Hi @André Johst

I'm sorry you're caught in the middle of this. It can be frustrating when two systems don't want to talk to each other.

I checked in with our team, and because the Trello connector for Microsoft is actually built and maintained by Microsoft (rather than Atlassian), our internal tools don't show us what's happening inside their "Admin Center" search.

Here is the best way to move this forward:

1. Check the Official Documentation: Microsoft maintains a specific reference guide for this connector. It covers the requirements for "Users" and "Elements" to show up correctly. You can find that here: Microsoft Connector Reference - Trello.
2. A Tip for Microsoft Support: Since Microsoft mentioned everything is set correctly on their end, you might ask them to verify if there is a specific API endpoint they are trying to reach that is returning an error. If they can provide an error code (like a 401 or 404) or a specific broken endpoint, our team can then investigate that immediately to see if something is wrong on the Trello API side.
3. Permissions Check: Double-check that the Trello account you used to authorize the connector has "Admin" permissions on the specific Trello Workspaces you're trying to pull "Elements" from. If the account is only a "Normal" member, the Microsoft connector sometimes fails to "see" the boards.

I know it’s a bit of a "he-said-she-said" situation right now, but getting that specific technical error from Microsoft is the key to us being able to help further!

Best,
Samuil

Hi André! Did you find any solution on this? I think I just found a bug on the "Add a comment to a card" tool on Copilot Studio. That connector doesn't have the "comment" input, so basically, I'm unavailable to write any comment on any card because there is no input for that

Hi Kevin, unfortunately I havent got any answer on this matter. Atlassian and Microsoft dont seem to care that their connectors dont work :/ 

I have found out that I can use it if I put all my Boards and Workspaces on public. THen again its a business tool and data safety wise no one should have his workspaces completely public...

So you use Copilot Studio for the connector? Do you also use a MCP?

@André Johst @KEVIN VARON 

First and foremost, please don't make your Trello boards public, that is a massive security risk for corporate data.

The integration issues you are seeing depend entirely on which Microsoft connector is failing. For the M365 Copilot Connector (used for indexing data), sync failures are usually caused by OAuth token expiration or identity mapping mismatches where Trello emails don't match Entra ID UPNs. For the Power Platform/Copilot Studio Connector, the missing "Comment Text" field Kevin mentioned looks like a Microsoft-side UI schema bug.

Please keep your boards private. I have flagged this thread for Atlassian to verify the API health on our end, but you will likely need Microsoft to investigate why that specific action field isn't rendering in Copilot Studio.

Best,

Arkadiusz🤠

Dear Arkadiusz, 

thank you for your answer. Unfortunately the Copilot Connector works only if the workspace is public, so in the end the connector is useless...

Thats a case where i wouldn´t sacrifice Security.

Hello @André Johst 

Trello has been experiencing an outage since yesterday.

I know, but I strated trying to connect trello with microsoft about 3 Weeks ago.

@André Johst 

Can you confirm which exactly Microsoft connector you mean?

There was some of them in History.

[André Johst]

Sure, its the Trello Connector, provided by Microsoft. Its not for Teams specifically but an overall Connecotr connecting trello to copilot
