The Exchange Team has completely reviewed and revalidated the Rollup 4 update for Exchange 2010 SP1 and has released an updated version for it. This release includes a fix for the SP1RU4 issue described in KB2581545.

If you already installed interim update KB2581545, then there is no direct need to install this updated release. If you do wish to do so, you must first remove this interim update before applying SP1RU4v2.

If you have not installed the interim update yet but do have SP1RU4 applied to your Exchange 2010 servers, you can directly install the v2 release without uninstalling the v1 release.

SP1RU5 is still on schedule to be released in August.

Exchange 2010 SP1 Rollup 4 has been removed from the Download Center due to an issue where messages from subfolders could get deleted when a parent folder is copied or moved within Outlook. Recovery would still be possible via the “Recoverable Items” folder (Dumpster).

If you have it already installed, you can uninstall it or contact Microsoft Customer Support and request interim update KB2581545 (KB article will be published later). It appears a fixed version of SP1 RU4 won’t be released and instead will be directly superseded by SP1 RU5 scheduled for August.

A new version of the Outlook Hotmail Connector has been released.
Checking the about box will reveal the version number 14.0.6106.5001.

The main new feature is that it now supports HTTPS, which means that all communication between Outlook and Windows Live services (Mail, Calendar and Contacts) is now being encrypted and thus fully secure. There is no need to change any settings to make it work; just install the latest version of the Outlook Hotmail Connector and you’re set.

Note:
You could see some Send/Receive errors and Outlook reporting “Limited Connectivity” for some time after installing this Outlook Hotmail Connector version. This is due to the fact that your old non-HTTPS Cookies need to expire first. This will fix itself over time. For details see the Send/Receive errors section.

Several other fixes are included in this release as well, including a fix for characters which are valid in Outlook but invalid in Windows Live Hotmail. Also, flagged items with reminders will no longer prompt even after it was dismissed. For more see; Full list of fixes.

Note: The 64-bit version of the Outlook Hotmail Connector is only needed when you use a 64-bit version of Outlook 2010.
