SharePoint Web Parts FAQ

An entry is shown as „(private)” if either the appointment subject is empty or the user does not have the permission to see the appointment details. Can you look at  your room mailbox settings from the EMS using the Get-MailboxCalendarSettings cmdlet and check the “DeleteSubject” setting:

Get-MailboxCalendarSettings "Conference Room 707"
...
RemovePrivateProperty         : True
DeleteSubject                       : True
DisableReminders                 : True
...

Enter command: Set-Calendarprocessing -Identity "Conference Room 707" -DeleteSubject $false

OR
You can check the permissions via your Microsoft Outlook Client by right-clicking on the calendar folder and choosing “Properties” and then selecting the “Permissions” tab:
The default calendar setting is „Free/Busy time“ (both for user mailboxes and resource mailboxes).
Can you thus set the “Read” permission to "Free/Busy time , subject, location":


If it's e.g. a room mailbox then you will need to temporarily add the room mailbox to your Outlook profile in order to be able to change the permission level.

The 401 error indicates that either the “User ID” or the “User Password” setting is wrong.
Please note that you should not use “Administrator” when running Exchange Server 2010 since apparently the Administrator account is specifically prohibited from accessing accounts other than its own (even though apparently it cannot even do that).

This indicates a problem with your SSL certificate. You might check with your network admin if the certificate is actually a valid one or you can also have the web part bypass the certificate check by appending „/2“ to the web part's „Exchange Server URL“ field:
https://yourExchangeServer.com/2
(replace “yourExchangeServer.com with your Exchange server url).
