Some people haven’t upgraded to Outlook 2010 Beta yet, can you believe them? Actually in the real world, many people are still on Outlook 2003. After you drop in Exchange 2010 into your environment, anyone that has Outlook 2003 can’t connect. What gives?
The problem is what gets us every time. The default settings. By default Exchange 2010 requires RPC connections to be encrypted. By default Outlook 2003 does not use RPC encryption. Whoops. How do we fix this?
Choice 1.) Disable Exchange 2010 requiring RPC connections to be encrypted. I really don’t like that choice.
Choice 2.) Either by GPO or Manually, update Outlook 2003 Profiles to use encryption as well as any new Outlook 2003 profiles rolling out, make sure they are configured to RPC encryption as well.
Choice 3.) Force people to upgrade to Outlook 2007 or Outlook 2010.They get other benefits besides this for upgrading as well, DR, performance, Mail Tips, etc.
Note This could also be a problem for Outlook 2007 profiles if you disabled RPC encryption when rolling it out.

For those that have installed Outlook 2007 Feb Update, http://support.microsoft.com/kb/961752/ or have installed Office 2007 SP2, when you start up Outlook for the first time after the update, Outlook has to do some optimization on your mailbox. This can take some time, it took over 15 minutes for my mailbox though it is rather large (over 15,000 items). While it is doing this it displays a message “Preparing Outlook for first use”. This may confuse some people since they have already used Outlook before. A better way to say it may have been “Preparing Outlook for first use after SP2 was installed”. More importantly you can modify the text to whatever you want in this message, “Optimizing for Performance, Please Call Help Desk With Any Questions”.
How do we do this?
1.) Install the hotfix or SP2 for Office.
2.) Go to the registry at HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Preferences and add a new string value called StoreUpgradeProgressTitle.
3.) In the value data box type whatever you want your message to be.
Pretty simple and a way to give you more control of what is being communicated to your end users.

Outlook has performance trouble when there are too many items in critical path folders such as Calendar, Contacts, Inbox and Send Item folder. Some numbers to keep in mind.
3,500 to 5,000 is a good gage according to the support article. The Exchange team blog also states that keeping the Inbox, Contacts and Calendar to 1,000 or less. The key to remember is that it isn’t necessarily the size of the times, but the number of items. Also if they are a blackberry user, that adds about 3.4 to 4 IOPS to their user account.

In Outlook 2003, when putting in cached mode, you can set offline folders to have encryption. You do this by going to More Settings (When selecting Cached Mode), Offline Folder Settings. There are three different settings.
-No Encryption
-Compressible Encryption (default)
-High Encryption
The encryption of these folders was not too good, so it has been removed from Outlook 2007. The now recomended way is to use EFS on the file system, and let that handle the encryption.

If you have noticed that your free busy info is becomming corrupted more and more frequently a security patch from March may be the culprit. If you have applied MS08-15 http://support.microsoft.com/default.aspx?scid=kb;EN-US;945432 there has been more corruption especially when network connectivity is lost.
