A colleague of mine recently pointed me to this great article on the scalability of office productivity suites on terminal services. The tests reviewed OpenOffice 2.1, Microsoft Office 2003, and Microsoft Office 2007.
For some unknown reason, Microsoft removed the ability to apply transform files to the Office 2007 suite when installing via MSI. On the flip side they made it much easier to deploy patches in MSP format to Office 2007 when installing via the traditional setup.exe. Give and take I suppose. Why is this a problem? Well if you want to deploy any or all of the Office 2007 suite via Active Directory Group Policy you will need to get a little creative.
This little script and associated registry file can help avoid lots of support calls about how to enable or disable cached mode in Outlook. To make this work you will need to do some manual testing which will give you the ideal values for your environment.
Officially Microsoft does not support the storage of PST files on file shares whether they are on a LAN or WAN. They have a knowledge base article specifically regarding this http://support.microsoft.com/kb/297019 but there is also a good commentary on the subject on the Microsoft Enterprise Platforms Windows Server Performance Team blog Network Stored PST files … don’t do it!
If the user cannot access their local contacts when attempting to send an email message the problem may be that their Outlook Address Book account has been removed.
