This video describes how to configure OAuth for user authentication with Microsoft 365 and Office 365 accounts, as well as adding the required information to your Sage 100 SMTP settings.
NOTE: Effective October 1, 2022, Microsoft made changes to Microsoft Exchange that will impact your ability to email in-product if you are on Sage 100 2020 or older. Microsoft has deprecated TLS 1.1, which is used in older versions as part of the Paperless Office email function. Microsoft 365 will also require OAuth for authentication.
If you are using Sage 100 2021.4 or higher, a supported OAuth configuration is available but will need to be configured. If you are not using Sage 100 2021.4 or newer, please reach out to your SWK CAM or contact us at info@swktech.com.
