• What version of Exchange you're using (On-premises Exchange or Exchange Online)?
• What happens when the rule runs - do signatures not appear at all, or are they appearing incorrectly?
• What type of rule did you create (transport rule or client-side)?
• 1. For On-premises Exchange:
  • Go to Exchange Admin Center
  • Rules > New Rule
  • Apply disclaimers/signatures > append disclaimer
  • Enter your HTML signature
  • Set conditions (like internal/external messages)

  Common issues to check:

  • HTML formatting in the signature
  • Rule priority (if you have multiple rules)
  • Whether the rule is enabled
  • If you're using dynamic fields, verify they're properly formatted
