As part of an Exchange 2003 to 2010 migration, we need to move many (> 1000) domain users from Outlook 2003/2007/2010 to OWA. Users will be instructed to access they're mailbox by OWA but also we need to prevent them to open Outlook. Solution I found till now are:
- Uninstall Outlook via GPO
- Prevent Outlook from start by using software restriction policy on filename
We would like to avoid Outlook uninstall. Software restriction GPO in quite weak (against renaming filename) and MD5 restriction in not an option because of the high number of executable versions around. Is there any Office specific GPO that would prevent Outlook to be executed? Any other suggestion? For example removing icons and links from start menu?
Thank you all for help.
