I purchased a trial version of Exchange 2007 and populated it with users for a SharePoinr site thinking I could turn the license, but licensed version of exchange 2007 only comes in a 64 bit version whereas the trial comes in 32 bit version. We have a 32 bit machine and therefore we cannot purchase the licensed version of exchange 2007 and instead have to purchase Exchange 2003.
1) Can I uninstall 2007 and reinstall 2003 while preserving user names and passwords or have I essentially lost everything?
2) In regard to Sharepoint, could I restore the site once Exchange 2003 has been installed?
OS is windows 2008 32 bit machine
