Check the user is connecting to Exchange via MAPI , I had a few setups where users were set to Active Sync instead
In this case, the solution was to run both commands on the exchange server:
Set-AutodiscoverVirtualDirectory “SERVER\Autodiscover (Default Web Site)” -WSSecurityAuthentication $True
Set-WebServicesVirtualDirectory -identity “EWS (default web site)” -WSSecurityAuthentication $true
This two command solved my problem
With an account that has full access to the Shared Mailbox , login to Webmail and Choose “Open Another Mailbox”
Enter the Shared Maibox and Click OK
Next Click on the settings Icon and Choose “Publish Calendar”
Next Change the Details Below
Next Send the External party the HTML or ICS file
This is due to the Exchange CalendarRepair
This happens when the user who left is the meeting organiser
You can disable this per use via :
Set-mailbox <User> -CalendarRepairDisabled $true
I based this script off of one referenced here : http://blogs.msdn.com/b/emeamsgdev/archive/2012/10/29/outlook-code-importing-bank-holidays-from-an-outlook-hol-based-csv-file.aspx?CommentPosted=true#commentmessage
CSV Format
However I modified Adding a Category to the item, as well as adding this to All Users of a AD Group recursively instead of a single user. This will add a list of Holidays to Users Calendars across an organisation. If run again it will not import duplicates and have fields there to delete the duplicate Calendar enteries if needed
The user running this will need the impersonation role setup see this :
New users can then have an email sent to them automatically ( http://blogs.technet.com/b/sukum/archive/2013/04/03/send-welcome-email-to-new-mailbox-users.aspx ) with a .HOL file to run ( P.S. The XML did not work in this , I have to add Lines 6-8 from this http://itnuts.wordpress.com/2013/09/03/exchange-2010-automatic-welcome-message-for-a-new-user/)

On a Week View in Outlook 2003 or 2010 , Outlook was showing the time of the appointment before the actual appointment but only on some appointments , so when this is printed it looks pretty odd!
The reason Outlook shows this time before is the scaling on the left hand side of the calendar. If you right click on the scale and choose smaller dividers e.g. from 30 minutes down to 15 this will stop it for Appoitments that can be divided by 15 minute intervals.
Per this article : http://www.outlook-tips.net/tips/tip-628-show-start-and-end-times/
Note that if the appointment splits a time period, such as if the length is not a multiple of the time scale you are using or the start and end times don’t fit nicely within the chosen scale, the times will show.
This is handled better with 2010 is you want to remove these or print the calendar if you have a calendar with appoitments with varyings time intervals!
