Outlook delegate calendar not updating
Outlook's Auto Archive feature automatically archives data at specified intervals.
If meetings aren't displaying on your calendar, they may have inadvertently been archived.
Scroll the calendar pane so that it displays an hour prior to when your work week begins.
Click the "Today" button in the Go To group, click the "View" tab, then click "Reset View." Click "Yes" to confirm.
The fact that meeting invites aren't displaying in your calendar may be the result of a temporary glitch in Outlook.
Restart the program to see if that remedies the problem. To do this, load the affected calendar and click the "Work Week" button.; microsoft.support = microsoft.support
