Webhook breaks before expire date

Question

Dear all,

for our application we establish webhooks for calendar changes in Outlook which expire after 24hrs. After 23hrs we renew this webhooks. We found that in rare cases (not calendar specific, not reproducible) webhooks then can't be found although they should be there (we know that they once worked because we got notification from those hooks). Is there any kind of scenario that these webhooks can break or vanish on your side before they should expire?

Best regards

Hi HulkDerShrek,

Good day.

Thank you for connecting with us in Microsoft community.

According to your description, I would like to share more specific information with you, in order of your certain situation, as the Office 365 global admin may need to contact our Office 365 support team on the back-end side through an open service request so they can diagnose this specific issue through some more technical resources, If necessary, they may be collecting certain logs information for further diagnosis. Since forum moderators have limited access permissions and resources, due to this reason we are unable to collect certain detailed information on the public forum for data privacy. 

For this standard process, here is the official document for the global administrator: Get support - Microsoft 365 admin | Microsoft Learn

Important note: If any organization's Office 365 Business/Enterprise / Education subscription is from a syndicated partner or reseller, and if the global administrator can't open the service request on their side, they may need to contact the reseller's support provider so they can help the global admin open the service request on their side. after the Office 365 support team can participate in the service request.

I would really appreciate your valuable time. Thank you for your kind cooperation.

Sincerely

Darpan
