Image not Rendering in MS Teams Adaptive Card

Hi Team,

We have a .net application which has been designed to send any communication or announcements to end users through MS Teams bot, as an adaptive card. The adaptive card contains image, text and button. The image and text are being fetched from Azure storage account.

The storage account is being accessible for only to the app service IP addresses which are whitelisted. But the image was not rendering the user’s MS teams bot. Hence we have been advised to whitelist the MS Teams server IP ranges (https://docs.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-world...).

But we could not able to whitelist multiple IP ranges in the Azure Storage account. Some of them are, 52.112.0.0/14,

52.120.0.0/14,

2603:1063::/38,

52.238.119.141/32,

52.244.160.207/32,

2603:1027::/48,

2603:1037::/48,

2603:1047::/48,

2603:1057::/48,

2620:1ec:6::/48,

2620:1ec:40::/42

It is causing that, the image is not rendering in user’s machine sometime. Kindly help us to sort out this issue on high priority.
