Test

running by curl it gets the notification as well:

sh("curl -k -X POST -H 'Content-type:application/json' --data '{\"text\":\"Message sent by jenkins\"}' ${WEB_HOOK_URL}")

where the variable: WEB_HOOK_URL is replaced by the full URL got by Microsoft Teams Connector

I found the following: link

The webook url has changed !

Is it working now for you? i have a web-hook URL which was created recently and includes the tenant's name as mentioned in the link you posted above but office 365 connector still fails to send notification with this error as well. Any updates?

[cprato79]

The notification has begun to works only after i restored the previous url as microsoft teams had generated it.

This is a temporary workaround working until Microsoft will not disable this behavior definitively!

The fix outlined in #240 (comment) worked, we upgraded from Oracle Java 8 to OpenJdk 11 as described here https://stackoverflow.com/a/55244659, and our new connector started working.

Thank you ! I will try.

My issue was actually a table-to-divs migration issue after an update to Jenkins 2.277.1. Some of the plugins were causing the configure UI to be broken. Once these plugins were disabled, the notifications started getting posted using incoming webhooks and office 365 connector plugin.
