Why does "saving" meeting changes on outlook calendar not show changes for all meeting attendees?

Hi @Kait S

Thank you for posting your question in Microsoft Q&A. 

We understand you are looking for a way to save minor updates to a meeting and have them synchronized with attendees, without sending unnecessary email notifications. 

As my research, when you edit the body of an Outlook meeting and simply click "Save and Close", it's a common and understandable assumption that the update will automatically reflect on all attendees' calendars. However, the change remains only on your personal calendar, and your colleagues continue to see the original meeting details. 

This behavior is due to how Outlook's calendaring system is designed. At its core, Outlook uses email as the primary method for synchronizing calendar events between attendees. Each participant has their own individual copy of the meeting on their calendar. For any changes to be reflected across all copies, an explicit update notification must be sent. 

When you, as the meeting organizer, make a change and choose "Save and Close" action instead of "Send Update", Outlook treats it as a personal note or minor change that doesn’t require notifying others. To ensure that all attendees receive and see your updates, whether it's a change to the meeting body or any other detail, you must click "Send Update". This action triggers Outlook to send an updated meeting invitation email to all participants. Once received, their Outlook clients will process the update and replace the existing meeting details with the new information.
