Outlook 2016 sharepoint calendar not updating
If you are making use of shared calendars in Outlook 2016 you may find that not all appointments are showing in the calendar or are disappearing.
Typically this happens when running Outlook 2016 in cached mode with exchange or Office 365.
But when a meeting time changes or is otherwise modified, the changes only apply to the event on either my personal calendar or the Share Point calendar (wherever I made the change).; microsoft.support = microsoft.support
So when there is a meeting, I create it in my personal Outlook calendar and then copy it to the Share Point calendar that shows in Outlook.
