Meeting updates with external contacts (GMail)

When we (Office 365 with Oultook 2016) send an invitation for a meeting to an external user, for example my GMail account, accepting it creates the entry in the Google Calendar.

However, if we update the meeting with an attachment or add a description, GMail receives a new meeting request instead of automatically updating the calendar.

Is this more a GMail issue or something that can be prevented with Outlook?
