Microsoft Office 2010 SP1 is now available on Microsoft Update. Office 2010 SP1 contains all Cumulative Updates released through April 2011 and all Public Updates released through June 2011 for the various applications that are part of the Office suite.

To check the version number of your installation, go to File, Help. The version number is displayed but not the service pack level. To see the familiar SP text, click on the Additional Version link under the Version number line.

In addition to the fixes listed below, SP1 contains additional improvements, including reducing the number of crashes, improving security, and fixing other issues that were too specific to include in this list.

Description of Office 2010 SP1 (MSKB)

To download and install, log into Microsoft Update and check for new updates. If you can’t or prefer not to use Windows Update, you can download the SP1 package:

Microsoft Office 2010 Service Pack 1 64-bit
Microsoft Office 2010 Service Pack 1 32-bit

SP1 addresses the following issues which generated a number of complaints in public forums:

• The ability to configure Outlook to always use the default sending account.
• Fixes an issue with the snooze time not resetting to 5 minutes and restores the “before start options” found in previous versions.
• Outlook warns of unsent messages still in the Outbox when closing. The method described in Unsent method to prevent accidental closing (still) doesn’t work in Outlook 2010, but you can set Outlook to send the message in the future (i.e., 2020) instead.
• The Quick Steps address book bug is fixed.
• IMAP new mail icon (fixed by a previously released hotfix and included in SP1)

The long list of issues addressed is below.

What’s not fixed in this update

This update does not fix the issue with plain text templates (Templates are converted to plain text messages) – the fix for this issue was released in a separate hotfix.

Activities not displaying Journal items was not fixed in SP1 either. Note that I am not hopeful that we will see any change to Activities at this point.

Issues fixed by the SP1 update

Snooze time: the old snooze options are back in Outlook 2010.

You can now select a default email account and it will be used for sending all messages.

Dual time zone bug affecting users swapping between DST and non-DST zones.

Reminders can be set for more than 24 hours without editing the registry.

All Outlook issues addressed by SP1

Many of these issues were addressed in previously released hotfixes and updates:

• Quick Contacts appears empty in the To Do pane when the system wakes up from sleep/hibernation and Microsoft Lync 2010 is running.
• When Outlook opens an e-mail message that contains pictures, the program tries to write files that have a .com file name extension to the Temporary Internet Files folder. This causes some anti-virus programs to mistakenly report that Outlook is trying to create an executable file.

• With Turkish regional settings, when you press “i”, Outlook (online) grouped view either stops responding or jumps to the first entry with “J.”
