User MailBoxs Creation to Enable Email Tracking

Hi,

I have been assigned to enable email tracking for Dynamics CRM. We use Dynamics 365 On-Premise 2016 and Exchange Server On-Premise. This feature has been used before with an outsourced company.

I am new to this and currently referring to the link below.

https://docs.microsoft.com/en-us/previous-versions/dynamicscrm-2016/administering-dynamics-365/mt622059(v=crm.8)?redirectedfrom=MSDN

Though everyone has Mailboxes created in the Exchange server, some users do not have active mailboxes in Dynamics 365.

Please advise how to migrate those user mailboxes to Dynamics 365.

Thanks and Regards,

Randima
