Exchange servers logs
By default, the protocol log files exist in the following locations:
- Front End Transport service on Mailbox servers:
Receive connectors: %ExchangeInstallPath%TransportRoles\Logs\FrontEnd\ProtocolLog\SmtpReceive
Send connectors: %ExchangeInstallPath%TransportRoles\Logs\FrontEnd\ProtocolLog\SmtpSend
- Transport service on Mailbox servers:
Receive connectors: %ExchangeInstallPath%TransportRoles\Logs\Hub\ProtocolLog\SmtpReceive
Send connectors: %ExchangeInstallPath%TransportRoles\Logs\Hub\ProtocolLog\SmtpSend
- Mailbox Transport Delivery service on Mailbox servers (Receive connectors): %ExchangeInstallPath%TransportRoles\Logs\Mailbox\ProtocolLog\SmtpReceive\Delivery
- Mailbox Transport Submission service on Mailbox servers (Send connectors): %ExchangeInstallPath%TransportRoles\Logs\Mailbox\ProtocolLog\SmtpSend\Submission
- Note: Protocol logging for side effect messages that are submitted after messages are delivered to mailboxes occurs in %ExchangeInstallPath%TransportRoles\Logs\Mailbox\ProtocolLog\SmtpSend\Delivery. For example, a message that's delivered to a mailbox triggers an Inbox rule that redirects the message to another recipient.
- Transport service on Edge Transport servers:
Receive connectors: %ExchangeInstallPath%TransportRoles\Logs\Edge\ProtocolLog\SmtpReceive
Send connectors: %ExchangeInstallPath%TransportRoles\Logs\Edge\ProtocolLog\SmtpSend

MailTips
|
External Recipients |
Outlook
Outlook on the web |
The sender adds an external recipient* or a distribution group that contains external recipients.
The MailTip informs the sender that the message will leave the organization, which can help them make the correct decisions about wording, tone, and content.
By default, this MailTip is turned off. You can turn it on using the Set-OrganizationConfig cmdlet. For details, see MailTips over organization relationships.
*If the recipient is external, but the recipient's domain is configured as a remote domain, the IsInternal setting determines whether the sender receives this MailTip (the External Recipients MailTip doesn't apply to internal recipients).
Note: The External Recipients MailTip isn't evaluated for external distribution group recipients where the distribution group is in a remote domain. |
