Azure Application Insights alert won't sent e-mail to teams channel

Question

Azure Application Insights alert won't sent e-mail to teams channel

Juul van de Wal 0

Within Application Insights I have setup a Alert. This alert will be used to receive notification in a teams channel within Microsoft Teams. Therefore I have created multiple Action groups.

Action group that sends an email to teams channel 'Alerting - PRD'
Action group that sends an email to teams channel 'Alerting - ACC'
Action group that sends an email to teams channel 'Alerting - TST'

Now there is this strange thing. When I link the alert to 'Alerting - PRD' I receive an e-mail within the teams channel. However when I link the same alert to 'Alerting - ACC' or 'Alerting - TST' I don't receive any e-mail within the teams channel.

I cannot understand why this wont work as the alert and action groups are identical except for the names. Also, there is no supression rule active and the e-mail adresses are valid.

Lastly, when testing the Action groups Application Insights says the test mail was send successfully, though I don't receive the test e-mail for the ACC en TST Action group.

Can someone help me understand why this is happening?

I suspect the working alert rule was created a long time ago and your recent alert rules are probably using the teams channel/group email address to set-up notifications. You must know that msteams channel/group can restrict on who can send email to it. Have you looked into moderation settings? https://support.microsoft.com/en-us/office/change-moderator-roles-and-settings-in-a-channel-in-microsoft-teams-6ac54758-3440-4f6a-9bd5-cebf97cb7ea6

Additionally, have you tried sending an email to this email address from your inbox, does that work?

Hi,

I have checked the moderation settings and there is no moderation active. Meaning everyone can start new posts.

Also, when I send an e-mail to this channel, the e-mail becomes visible in the channel. This even does make it more strange why sending an e-mail via Application doesn't work.

Do you have more suggestions?

Kind regards,

Hi @Anonymous
Thanks for your Update.
There could be a few reasons why the alerts linked to 'Alerting - ACC' and 'Alerting - TST' aren't sending emails to the Teams channels, while 'Alerting - PRD' is working fine.

Make sure 'Alerting - ACC' and 'Alerting - TST' are set up correctly and that the email addresses are valid and set up to receive emails. Check if the email server settings allow emails from Application Insights to be delivered to Teams channels. Sometimes, configurations or restrictions might block emails. Look for any spam filters or inbox rules that could be affecting email delivery to those action groups. Ensure you haven't hit any rate limits for sending emails to Teams channels, as too many emails to one address can get blocked. Since the test email was sent successfully, double-check the logs or history of the action groups for any errors or warnings about email delivery. Confirm that Teams channel settings allow emails to be posted. Even if moderation is off, other settings might affect email visibility.
