Recently SP Designer Workflows in SharePoint Online have been suspended with error showing as Access denied. On Investigating it has been noticed that if a user is not present in a group , workflow is not sending mail to that group. Even Site collection Admin is unable to send mails through workflow if Admin is not a member of the group. This is a very major change but it has effected the users across the Globe. Even though we can use flows in which we send a http request to get group members this is not the same case for SP designer workflows, As many organizations still use SP Designer workflows it would be great if this change is reverted
