Total Access Emailer and Office 365 SMTP with TLS

Total Access Emailer is the most popular email automation system for Microsoft Access. Total Access Emailer uses your SMTP server to send emails. A popular choice is the SMTP server provided by Microsoft Office 365’s Exchange Server.

Total Access Emailer and the Office 365 SMTP Server

Total Access EmailerAssuming the account is properly configured to relay email messages (Mailbox Delegation), Total Access Emailer has supported Office 365 since it was introduced.

Over the years, Microsoft has increased security on their site and adjusted configurations for their SMTP server. You can connect via SMTP protocol using an approved IP address or Transport Layer Security (TLS) protocol for a specific email address.

Instructions for configuring Office 365’s SMTP server are provided here:

Problem with TLS Connections

In the last week, we confirmed that Office 365 and Windows made changes that cause Total Access Emailer to be unable to send emails with its TLS connection protocol with an error like this:

SMTP protocol error: TLS 1.0 and 1.1 are not supported

The message implies the need for TLS 1.2, but recent versions of Total Access Emailer already support TLS 1.2.

What is not supported is TLS 1.3 that recent changes with the Office 365’s SMTP server and Windows seem to require. Here’s a Microsoft article about TLS 1.3: Taking Transport Layer Security (TLS) to the next level with TLS 1.3.

NOTE: TLS still works with many other SMTP servers including Gmail’s smtp.gmail.com (details for Using Total Access Emailer and Gmail).

Workaround: Use SMTP Protocol

If you are having trouble using TLS protocol, the SMTP protocol still works for Office 365. You need to authenticate your IP Address where you’re sending the emails. Remember to use the Temail.txt to store the FROM email address to use for validation as instructed in the referenced page above.

We realize that is not possible for all the environments of Total Access Emailer users.
