Task Requests in Outlook Losing Accept/Decline Buttons

Issue

When you send a task request in Outlook, the recipient’s message may not display the Accept and Decline buttons, and the task details may appear scrambled or unreadable.

Cause

This occurs because Outlook originally sends the task request in Rich Text Format (RTF), but a transport component later converts the message to HTML. During this conversion, the task action buttons are removed, and the formatting of the task details is broken.

Workaround

To prevent this, you can configure an Exchange Transport Rule to exclude messages with subjects beginning Task Request: from being processed by Crossware Email Signature.

Steps to Configure the Transport Rule

1. Open Exchange Admin Center and create a new transport rule.

2. Configure the following settings:

   1. Condition (If):
      Header: Subject
      Matches regex: ^Task Request:

   2. Action (Do the following):
      Set a custom header, for example:
      X-CWesigProcessed = Y

3. Rule Priority:
   Set the priority of this rule higher than the Crossware Email Signature transport rule.
   (This ensures task requests are excluded before signature processing is applied.)
