You may be unable to view free/busy calendar information when you use an Outlook 2007 application
On This Page
SYMPTOMS
When you use a Microsoft Office Outlook 2007 application, you may experience the following issues:
- You cannot view free/busy information when you schedule a calendar meeting request with another user who uses the same hosted messaging environment. Additionally, a "No Information" message is displayed toward the end of the Outlook calendar item.
- In coexistent environments, you cannot see free/busy information that is being exchanged between Microsoft Online and the on-premise Microsoft Exchange server.
CAUSE
This issue occurs because Outlook 2007 may be unable to connect to the Exchange Server 2007 Availability service and to the Exchange Server 2007 Autodiscover service to view free/busy information.
Outlook 2007 may be unable to connect to the Availability service and to the Autodiscover service for the following reasons:
- Cause 1
You run Outlook 2007 without 2007 Microsoft Office Suite Service Pack 1 (SP1) installed. - Cause 2
Domain Name System (DNS) servers that are used to provide naming resolution do not have either an Autodiscover Canonical Name (CNAME) record or an Autodiscover Service Location (SRV) record that points to the Microsoft Online hosted messaging services.
Note The Availability service provides calendar information for users. This is known as free/busy information. The Autodiscover service provides this information to the Availability service. To do this, the Autodiscover service locates and provides the external URLs and the internal URLs to the Outlook 2007 client.
RESOLUTION
Resolution for cause 1
To resolve this issue, download and install 2007 Microsoft Office Suite SP1. To download 2007 Microsoft Office Suite SP1, visit the following Microsoft Web site:
Resolution for cause 2
To resolve this issue, create or modify the Autodiscover CNAME record or the Autodiscover SRV record. For example, add the following CNAME record to point to the Microsoft Online hosted messaging services:
Autodiscover.companySMTPNamespace.com CNAME AutoDiscoverRedirect.microsoftonline.com
Note You create or modify the Autodiscover CNAME record or the Autodiscover SRV record together with the DNS host provider.
If you cannot see the free/busy information that is being exchanged between Microsoft Online and the on-premise Microsoft Exchange server in a coexistent environment, migrate the company information to the Microsoft Online environment.
MORE INFORMATION
The Internet Free/Busy (IFB) feature in Outlook lets you see when other users are free or busy so that you can efficiently schedule meetings. Outlook users have the option to publish their free/busy information to a user-specified URL file server. You can share this URL file server with all users, or you can limit the URL file server to a specific set of users.
