Hello
I have a Contoso tennant for Developer tasks
We are creating one web app for room reservations (using Microsoft Graph) in a corporation using 365 accounts
After some "ok" tests, the reservation has started to fail because the sender has been put in Spam list
the fail message email that the sender email account get is
Your message wasn't delivered because the recipient's email provider rejected it.
Remote server returned '550 5.7.501 Service unavailable. Spam abuse detected from IP range...
The api we are using use the calendar
var res = await graphClient.Users[currUserId].Calendar.Events
.Request()
.AddAsync(evento);
Any trick to avoid this problem?
Thank you in advance
