The legacy Microsoft Teams connector has been deprecated in Atlassian Automation

[#1]

As of today, all automation rules that use the legacy Office 365 connector webhook in the Send Microsoft Teams message action can no longer be saved or updated, until they are migrated to the new Microsoft Teams workflow.

What’s changing?

• Microsoft is retiring the Office 365 connector. As a result, the legacy webhook has been deprecated in Atlassian Automation.

• From today onwards, any rule still using the legacy webhook cannot be saved or updated until it is migrated to the new Microsoft Teams workflow webhook.

What do I need to do?

To update your automation rules:

1. Go to your Teams channel and select … > Workflows > Post to a channel when a webhook request is received.

2. Copy the new webhook URL.

3. Paste this URL into the Send Microsoft Teams message action in your automation rule.

4. Save your rule.

FAQs

Can Atlassian migrate my rules for me?
No. Since some legacy webhooks may be called from non-Atlassian systems that we don’t have access to or aren’t aware of, rule owners will need to migrate them manually.

How do I find impacted rules?
Filter the rules in your rule list by the Send Microsoft Teams message action.

Hi,
@Phoebe Peng 

I have automation rules that are sending to MS Teams via a Power Automate Workflow. As of today I have started receiving errors in the Audit log saying the Automation has some errors, specifically that it is "Unable to run this component" for the "Send Microsoft Teams message" component, however it also states it successfully sent the teams message.  

The messages are posting successfully to the teams channels and I haven't made any changes to the rules for this error to start occurring, but I still get the emails detailing the errors - can you help me understand why this is happening?
