Important Information For Sage 100 Users About OAuth and TLS

July 6, 2022 by Wayne Schulz

By October 1, 2021 users of Sage 100 should be on versions 2021.4 / 2022.1 or higher if they are using Microsoft to send email through paperless office. This is due to Microsoft requiring OAuth for all API endpoints such as Exchange on-line and Office 365 email tenants.

In addition, Sage will no longer support TLS 1.0 or 1.1 effective by the end of the summer 2023. This is of more concern since a broader array of integrations may require TLS 1.2.

For TLS compatibility you should be on Sage 100 2019.4 or higher although we strongly recommend that you adopt the same requirements as OAuth as noted above which requires Sage 100 2021.4+ or Sage 100 2022.1+ no later than October 1, 2022.

Sage 100 & 300 Alert

By October 1, 2021 – Upgrade to at least 2021.4+ or 2022.1+ in order to maintain compatibility with Microsoft OAuth which will be required to use Microsoft email for sending documents from Sage 100. By upgrading to one of the above versions you will also meet the TLS 1.2 requirements.

What if I don’t upgrade by October 1, 2021? – You lose the ability to send email through Microsoft’s servers using a simple login and password.

By Summer 2023 – Upgrade to at least 2021.4 or 2022.1 in order to maintain compatibility with TLS 1.2 requirements for communicating with Sage. Note that if you are not sending email through a provider who requires OAuth you can upgrade to Sage 100 2019.4 as the minimum compatible level for TLS 1.2.

What if I’m not on 2021.4, 2022.1 or 2019.4 by Summer 2023? You will lose the ability to communicate to Sage using TLS 1.2 and your system will enter a read-only status.

We recommend strongly that you adopted either 2021.4+ or (preferred) 2022.1+ prior to October 1, 2022 for maximum compatibility with the changes noted above.
