Problem with workflow notifications

Problem with workflow notifications

Hi!, 
This week change our company mail system, from google apps to office 365 . We have various workflow to notify us, by email, when a user make a change.

Since we migrated,  the notification mails are not sent anymore or at least they do not reach us. 


Do we forget to make any changes in zoho or our dns records? Is there a way to verify if the notifications are sent?


Sincerely, 
Bruno
