The February updates for Outlook 2010 include fixes for the following issues.
The MAPI over HTTP transport protocol is not supported on Windows XP. This hotfix will prevent Outlook from attempting to use it if you use Outlook 2010 on Windows XP.
When you use a proxy server to connect to the Internet and use the MAPI over HTTP protocol to connect to Exchange, when the proxy server is not working Outlook cannot connect to the mailbox even though the Exchange server is on the bypass list.
Even though a policy (DisableCrossAccountCopy) is set to prevent copying or moving items between accounts, Outlook still lets certain user rules move or copy email messages to an Outlook Data (.pst) file or to another email account.
When you configure Outlook 2010 to connect to an Exchange 2010 mailbox in online mode and save a Rich Text format (RTF) email message as an Outlook template (.oft), the template opens in HTML format instead of RTF format.
Nonrecurring calendar appointments that are created in Outlook Web App (OWA) cannot be auto-archived.
When you view the property information of some specific email messages (.msg) in Windows Explorer, a memory leak may occur.
Fixes an issue in which text in some dialog boxes may appear clipped in some languages and includes translations for a new feature in Outlook 2010.
