we have an account on office365. from May 18th 2019 we are facing some issue in delivering the e-mails to groups. some of the group members are not receiving the e-mails some times. This is especially when

in our site contact tab fill the form. once they fill the form and save the e-mail will be drafted to sales group but some users in the group are not receiving the e-mail and for some uses in the sales group receives an e-mail but moved to Junk folder. 

please let me know is there any new release by office365 that is blocking.

Try to check the message header of emails that was junked and delivered (successfully). We can know why the message is junked. Also, are you setting up multi-function device or application to send email using Office 365? If yes, please refer to this - How to set up a multifunction device or application to send email using Office 365
