Hello,

yesterday when I tried to add an incoming webhook I got the generic error message that "something went wrong".

Now when I hit "add" on the incoming webhook, I just get a blank page.

Following the network traffic, I found out that the request on

/connectors/IncomingWebhook/Manage/New?MailboxAddress=e880cc50-6518-49f2-9abd-549668ec3b86%401b94b413-6d28-42b0-bf1a-7bb10aa22440&client=SkypeSpaces&SSThread=19%3ApJFBJXqrH3tfd-wLD5uuJOE6xrwauZN_0znaj0OeEAg1%40thread.tacv2&HostName=teams.microsoft.com&culture=de-de&ssApiHost=de.ng.msg.teams.microsoft.com&iframe=true&SSTheme=default&isDesktopClient=false&enableConnectorApps=true&providerId=203a1e2c-26cc-47ca-83ae-be98f960b6b2

returns a server error 500.

We need this desperately. Thankful for any help!

    We checked this from our side by creating a new incoming webhook and are able to create successfully.

    Tested in Microsoft Teams version 24187.501.2981.3768. The client version is 49/24053101421.

    FYI, O365 connectors within Teams will be deprecated and notifications from this service will stop.

If you want to continue receiving these types of messages, you can use a workflow to post messages from a webhook request. Set up workflow

    I have the same problem and can reproduce it on different machines with different clients (web vs native) and two different tenants/organizations. Do you have any suggestions?

    Now when I hit "add" on the incoming webhook, I just get a blank page.

    Same for us today. I can add the group, go to the channel, click on Add Webhook, and get a blank screen with the cursor spinning.

    We need tools we can rely on.
