Improvements and Fixes
- Improves localization to make sure that the meanings are accurate in multiple languages. This update also fixes some layout issues that occur in localized versions of Outlook 2013.
- Improves user experience by excluding unnecessary syncing between Outlook and Exchange servers.
- Improves user experience by adding a warning when you try to change Default or Anonymous permissions. The warning message may resemble the following:
- Improves Customer Experience Improvement Program logs by including additional diagnostic/trouble-shooting information.
- Improves managerial effectiveness in Outlook 2013 by using Group Policy to let administrators disable the Delegate Access entry in the Account Settings drop-down menu located in the Info section of backstage (File tab).
- Introduces the getSelectedDataAsync and setSelectedDataAsync methods to Outlook 2013.
- Fixes the following issues:
- You cannot recover or delete the deleted items from the Recover Deleted Item window in Outlook 2013 by using a keyboard without a mouse. This behavior limits the effectiveness of assistive technologies such as Windows Narrator.
- Assume that you configure Outlook 2013 to connect to an Exchange 2013 mailbox in online mode. The scroll bar in the Inbox folder may stop working if the Show in Groups option is enabled and there are many email messages in the folder.
- Assume that you enable Direct Access or Unified Remote Access (or similar VPN technology), and then you do not configure the default gateway on your network. You cannot connect Outlook 2013 to Microsoft Exchange Server by using MAPI over HTTP.
- Assume that you configure Outlook 2013 to connect to your mailbox by using MAPI over HTTP. When you try to log on to your account by using an expired password, the Outlook status bar displays "DISCONNECTED" instead of "NEED PASSWORD."
- Nonrecurring calendar appointments that are created in Outlook Web App (OWA) cannot be auto-archived.
- Assume that your Exchange administrator is performing a recovery on your mailbox, and you have previously configured your Outlook profile to connect to your mailbox in Cached Exchange mode. During the process, when you start Outlook 2013, you may see a dialog box that prompts you to connect to a temporary mailbox in online mode. The dialog box may resemble the following: This behavior is expected.
After the recovery is finished, when you start Outlook 2013, you continue to see this dialog box. Additionally, Outlook 2013 continues to connect in online mode instead of reverting to Cached Exchange mode. This behavior is unexpected. - Consider the following scenario:
- You connect to an Exchange 2013 mailbox by using Outlook 2013.
- You search for email messages in the mailbox by using a search term.
- You click an email message from the search result to view the email body in the reading pane.
- Fixes the following issue that typically occurs during an Exchange migration from one forest to another. Consider the following scenario:
- You are a delegate of a user who belongs to a forest that is different to yours.
- There is a one way trust that enables logon of the given forests so that you can access the mailbox of the given user.
- You open the mailbox of the given user as a delegate by using Outlook 2013 SP1.
- Consider the following scenario:
- You configure Outlook 2013 to connect to your mailbox that is hosted on an Exchange Server 2007-based server.
- You send a meeting request to another user.
- You send an update of the meeting request to the user, and then you receive the response from the user.
- Consider the following scenario:
- The check box of the Open replies and forwards in a new window option is unselected under Outlook Options -> Mail -> Replies and forwards. Therefore, when you reply or forward email messages, inline replies are used.
- You add a Boolean type column, such as "Receipt Requested", to an Outlook table view. Then, you change its column format to "Icon". Therefore, the cells in the column are displayed as check boxes instead of text.
- You reply or forward an email message so that you see the text "[Draft]" in the table view.
- Consider the following scenario:
- You configure Outlook to connect to your mail server by using the Exchange ActiveSync Protocol (EAS). The most common EAS server is outlook.com, but any server that uses EAS exhibits the same problem.
- You add a contact to a color category and let Outlook sync the change to the server.
- You make some changes to the contact but do not change the color category, and then you let Outlook sync the changes to the server.
- You cannot recover or delete the deleted items from the Recover Deleted Item window in Outlook 2013 by using a keyboard without a mouse. This behavior limits the effectiveness of assistive technologies such as Windows Narrator.
