Hi,
I'm in a college were I migrated their systems to Exchange 2010. Prior to the migration they had an unusual setup: Mdeamon server pushing mail to Exchange 2003 which in turn pushed mail to an Exchange 2010 server. The Exchange 2010 was installed on a DC which isn't the best thing to do. I ended up installing a new Exchange 2010 server, moved mailboxes to the new Exchange 2010 server and decomissionned the old Exchange 2003 and Exchange 2010 servers.
For a reason we can't find, people using Office 2007/2010 on Windows XP are keep being prompted for password. I've done the following so far:
- Validated certificat(issued from enterprise CA)
- Tried deleting Outlook profile and recreate it
- Set-OutlookProvider EXPR -CertPrincipalName:""msstd:yourdmoain"
Still, users are being prompted for password in Outlook for no reason.
PC: Windows XP SP3 /w Office 2007/2010
Server: Exchange 2010 SP1 on Windows 2008 R2
AD level: 2003 native
