I have a user who can't send email from dynamics.
Everytime he creates an email activity and hit "send", the mail is synchronized to Outlook to send, but the recipients email contains a prefix "=SMTP:" which looks like so :
"=SMTP:email@contoso.com" instead of just "email@contoso.com"
This obviously lead to a sending failure in Outlook.
I cannot understand how this happens only for this user.
The user is running Dynamics 365 through Chrome and Outlook 365, Window 7.
