Any organization still using Dynamics GP, please be aware that Microsoft has released two updates. These two updates are required to ensure system functionality and security. Please be sure to reach out to your client account manager as soon as possible to discuss what is right for your company.

Dynamics GP Updates

If you are using the email functionality in Dynamics GP, Microsoft has announced you must be on the Modern Lifecycle (GP 18.3 or higher) to continue to use this functionality without issue by October 2022.
