Hello,
I'm aware of the retirement of the 365 Connectors, however, the original post indicated that they would remain functional until the end of 2025.
I tried creating new connectors configuration to channels, yet, every time I try to send a message through the generated URL I receive a 403 error back with the message "Webhook Url is not updated".
The workaround solution of reconfiguring the connector does work for the "Incoming Webhook" connector, but doesn't for our own Custom Connector.
Any advice, fix or workaround for the issue?
Thanks!

2025-03-12T09:16:06.08+00:00 Hi Vinicius De SouzaO365 Connectors service in Teams will be retired at the end of 2025, however it was recommended that you update your connector immediately to prevent any disruption to connector services. URLs for all webhook-based connectors must be updated by January 31, 2025, for the connectors to continue posting messages into Teams.
Have you updated that?

2025-03-12T14:18:34.7733333+00:00 I'm having issues with newly configured connectors, not previously configured connectors.
I created a new configuration yesterday and still, it fails with the error I mentioned earlier.

I tried to configure a new connector, and yet I'm seeing the "Webhook Url is not updated" error.
