Hi,

Do you integrate Dynamics 365 with Exchange Online? If so, the possible reason could be that,

Hope it helps.

Hi Judy,

We have licences for Dynamics 365 and Exchange, and I "simply" configured a conenction between the two application throught the server side synchronisation.

Whan I am sending an email from Outlook (OWA), it's working nicely but from Dynamics, I have this message.

Hi,

Do you change your email integration method to "Server-side sync" in Dynamics 365 email settings for your mailbox and generally setting in Dynamics 365.

Hello,

In fact, I created a new support ticket from Office 365 adminisration portal.

My email adress was (during a few days) in the Anti-Spam list. Automatically, the email adress was removed from it. :)

I advice to create a support ticket if anyone has this kind of case.

Thanks and Regards !
