We are having trouble making this work. I am looking for detailed instructions beyond what is on the 3CX website. We submitted a ticket and receive the link to the 3CX impersonation page. https://www.3cx.com/docs/how-to-create-impersonated-user/#h.5egg3xlsldex Any help is appreciated. We have created the Impersonated account and assigned an O365 license and entered the creds in the Contacts - O365 module on the 3CX server.
