SMTP Authentication must be enabled on your Exchange server for Sage 100 to properly communicate with it, failure to do so may lead to SMTP Authentication errors. See https://docs.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/authenticated-client-smtp-submission for more information.

Note: There are numerous different server programs and providers that provide the services of an SMTP e-mail server. Sage does not test Sage 100 with all e-mail services/programs/providers. Sage 100 Customer Support is not responsible for knowing the exact combination of program or provider, security or permission settings, inbound or outbound rules, account logins, passwords, bandwidth restrictions, etc. to enable successful e-mail delivery. The specifics of services, programs, and providers are subject to change. If an error is encountered, troubleshoot based on the Chilkat error log information. You may need to try various settings, or test an alternate service, program, or provider.
