Outlook calendar not updating meeting changes
Additionally, you will learn how to make Outlook send a specific type of update, depending on the meetings properties that you want to change.
In a few words, in Outlook 20 you can no longer make critical changes on a meeting without sending an update.
This issue has been reported in organizations with Microsoft Exchange, Outlook (2010, 2013 or 2016), Apple i Phones/i Pads, Active Sync devices, Apple Macs running Outlook 2011 or 2016, and RIM Blackberries.
The difference is that any of your previous edits to Public properties are overwritten if the meeting organizer changes any of them and sends you an update to the meeting (regardless of whether it is an informational or full update).
User B leaves the meeting as it is, however user C changes the sensitivity to public, the importance to normal, the free/busy to busy and the reminder to 10 minutes, after which he saves and closes the meeting.
Adding Notes to a meeting request should never send updates.
If Outlook wants to send an update and the only change was notes, make sure you have the latest updates for your version of Outlook then try this: Save the changes using Ctrl S or the Save icon , then click the X to close. If you are changing the time to add travel or preparation time, I highly recommend creating an appointment for the extra time instead. However, there is a way to trick Outlook into thinking the update was sent: set Outlook offline before sending the update, then open the Outbox and delete the update before going back online.
The easiest way to verify this is the problem is to log in to your Outlook Web Mail, if you are using Office 365 you can log in at https://portal.using your username and password.
