If you regularly use Microsoft’s Internet Explorer 11 with Microsoft’s Office 365 you may notice some occasional glitches. One problem we have come across is that the SharePoint calendar may appear to be stuck in month view and not show the times of appointments.
To remedy this you need to add sharepoint.com to the “Compatibility View Settings” list. You can do this by going to the Tools menu (press Alt if you can’t see it it), select “Compatibility View Settings” and then add sharepoint.com to the list.
You should now be able to view the calendar correctly!
