Question:

Why does a CRM Validation Rule Work Online but Not Offline?

Answer:

There are a number of possible root causes for this issue:

• Offline Validation Rule functionality not configured
• Object does not have an Active VMOC for the offline platform
• Refresh Validation Rule Data button has not been clicked after changing online validation rule
• End-user does not have read Field-Level Security (FLS) to a field referenced in the rule
• Unsupported area or field
