Accessing a shared Calendar of a Exchange 2010 mailbox from an Exchange 2013 mailbox via OWA

Scenario:  A mailbox on Exchange 2013 SP1 cannot open or edit calendar entries of an Exchange 2010 SP3 mailbox using OWA (Outlook Web App).  Attempting to open the calendar entry does not appear to do anything. The user has explicit rights to this shared calendar.

Cause:  Per Microsoft, this is an unsupported configuration for OWA.  This is by Microsoft design.

Work Arounds: 
1. Use an Outlook client to view calendar information between the 2013 and 2010 mailboxes.  
OR
2. Move the Exchange 2010 mailbox to Exchange 2013.

Recommendations to avoid IOS Calendar Corruption with Exchange Mailboxes

Scenario: An entry on an IOS calendar shows incorrect times for an appointment, has disappeared, or is missing information, although the calendar entries in OWA and Outlook is correct. Specifically a single occurrence of a repeat appointment/meeting has one of the symptoms from above.

Recommendations from support:


1. Microsoft recommends running the same version of Outlook on all the computers. Mailbox owners and any delegates need to be using the same version of Outlook with the latest updates on all the computers that are used for calendaring. If you are in a mixed environment of Mac, Windows and iOS devices, each platform needs to be using the same version and each device should have the latest updates. 
2. Only one person should process meeting requests. Other people, computers or devices that receive the meeting request should ignore them, they should not delete or process them. Users should have a maximum of 2 delegates.
3. Manage your calendar exclusively from Outlook or OWA. Don’t accept, decline, modify or invite others to appointments from your mobile device. You can create new appointments on your mobile device.
4. Verify that the device has the latest iOS version installed. (Please verify this before adding the Exchange account to the device. Sometimes, new devices are running an older version of iOS, so it is a good habit to confirm that all updates are applied before adding Exchange accounts)
5. To change an entire series of meetings, cancel the original meeting and create a new one. To change one instance, cancel just that meeting and create a new one to replace it. Always put an end date on a recurring meeting.
6. A “corrupt” meeting will remain that way until you delete it. If it is a recurring appointment, delete all occurrences and reschedule it.
7. When scheduling a recurring meeting, Microsoft recommends setting the end date no more than 6 months. If you need to schedule a meeting for a longer period, start a new recurring meeting.

8. Making multiple changes to recurring events can contribute to unexpected results.

Can’t load OWA Premium by using Internet Explorer 11 in an Exchange Server environment

When you try to access Outlook Web App (OWA) Premium by using Internet Explorer 11 in a Microsoft Exchange Server 2013, Microsoft Exchange Server 2010, Microsoft Exchange Server 2007, or Microsoft Exchange Server 2003 environment, OWA Light is loaded instead.

To work around this issue in Exchange Server 2013, Exchange Server 2010, Exchange Server 2007, or Exchange Server 2003, use Internet Explorer 11 in compatibility mode to access OWA. To do this, press F10 to display the menu bar, go to the Tools menu in Internet Explorer 11, and then click Compatibility View settings. Then, add the OWA site to the list of sites to be viewed in compatibility view.
