Refer to the table below for the Mail activities that are unsupported when using the Activity Migrator tool.

| Outlook Desktop Mail Messages Trigger (`OutlookMailMessagesTrigger`) | **Unsupported** | The activity is **skipped during migration**.The `Outlook Desktop Mail Messages Trigger` cannot be automatically migrated since there is no counter part trigger activity that retains the full behavior of the old trigger.Therefore, the migration has to be done manually after the tool has finished the migration of other supported activities.The trigger has to be manually replaced with one of the available triggers for the O365 package: `Email Received` (triggers when an email is received) or `Email Sent` (triggers when an email is sent. Can apply various filters to the trigger in order to filter out unwanted sent emails).Unfortunately, there is no O365 trigger that monitors a certain mail folder like the old Mail trigger did. The closest trigger option for this behavior is the `Email Received` from the O365 package. |
