关于Actionable Message AdaptiveCard 1.0在iOS Outlook最新版本无法显示的技术咨询

Hey there, sorry to hear your actionable messages aren't showing up on iOS Outlook 4.2412.0—let's walk through what might be causing this and how to troubleshoot it.

First, let's recap your situation to make sure I'm on the same page:

• Your AdaptiveCard 1.0-based actionable messages aren't displaying at all on iOS devices running the latest Outlook for iOS version (4.2412.0)
• You checked official documentation which claims support for version 4.34, but this version doesn't actually exist
• Your team has invested significant time into building these tools, so resolving this is critical

Here are the most likely causes to investigate:

1. Documentation Version Number Error or Lag #

It's highly probable that the documentation has a typo or hasn't been updated to match the latest iOS Outlook releases. The "4.34" mentioned might actually be a mistake (maybe meant to be 4.24?), or the docs are lagging behind real-world version rollouts. This means the latest 4.2412.0 might not have full support for AdaptiveCard 1.0 actionable messages yet, or there's an unreported compatibility bug in this specific release.

2. Invalid AdaptiveCard Syntax or Originator ID #

Looking at the snippet of your card JSON you shared:

{
  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
  "type": "AdaptiveCard",
  "originator": "my secret not sharing",
  "version": "1.0",
  "body": [
    {
      "type": "TextBlock",
      "id": "90451e68-1bc7-385b-93f3-eaf1384e282a",
      "text": "HELLO IOS",
      "wrap": t...
    }
  ]
}

There's a clear syntax error here—the "wrap" field is cut off (ends with t...). Incomplete or invalid JSON will definitely cause Outlook to fail rendering the card. Additionally, the originator field requires a valid, Microsoft-verified ID. If this value is incorrect or hasn't been properly authenticated, iOS Outlook's security checks will block the card from displaying.

3. Regression in the Latest Outlook for iOS Version #

New app updates sometimes introduce unintended regressions. The 4.2412.0 release might have changed how it parses or renders AdaptiveCard 1.0 messages, breaking backward compatibility with your existing cards. This is especially common if the update included changes to actionable message handling.

4. Delivery Channel Restrictions #

Make sure you're sending the actionable messages through a supported channel (like Exchange Online). iOS Outlook might have stricter limitations on actionable messages from non-verified or third-party delivery services, and these restrictions could have been tightened in the latest version.

Troubleshooting Steps to Try: #

• Fix all syntax errors in your AdaptiveCard JSON first (complete the "wrap" field with a valid value like true) and retest
• Verify that your originator ID is correctly registered and verified with Microsoft
• Test your card on an older version of Outlook for iOS (e.g., 4.23.x) to see if it works there—this will help confirm if the issue is specific to the 4.2412.0 update
• Reach out to Microsoft support to report the documentation discrepancy and the rendering issue, as this could be an official bug or oversight
