Resolution
Please first note:
This error has been resolved on the latest version of Sage 200 Evolution. 
If you are unable to currently upgrade to the latest version please note the following statement from Microsoft:
“Exchange Online no longer supports use of TLS1.0 and TLS1.1 in the service as of October 2020. This change is due to security and compliance requirements for our service.”
Microsoft also stated the following:
“While no longer supported, our servers still allow clients to use those older versions of TLS when connecting to the SMTP AUTH endpoint (smtp.office365.com).”


Therefore, consider the following advice to resolve the above error:
Please note:
It is highly recommended that especially Step 1 in the solution below should be implemented by an IT technician as it involves technical skills and an understanding of the client’s local e-mailing infrastructure and general setup.
1. Within the Exchange Server PowerShell (Exchange Management Shell), involving the Set-TransportConfig cmdlet, set the Transport Config to allow Legacy TLS
 2. Also, do the following:
     a) Within the Evolution company, go to Administration | System Configuration | System Wizard | E-mail tab.
     b) In here setup the Outgoing Server field as seen below. Ensure the User Name and Password are correct and then save your changes.
