We have a network with ~150 PCs. Most of the PCs are running Outlook 2007 however newer PCs are running Outlook 2010.
All the users have roaming profiles enabled and some log into different machines.
When a user logs into an Outlook 2010 PC and runs Outlook, the profile is “upgraded” automatically. If they then log in to a 2007 machine they are greeted with a message saying that the profile has been upgraded to a newer version. Outlook will then continually prompt for a username/password and refuse to work until the profile is deleted and a new profile created.
This is obviously a pretty crappy situation to be in. Upgrading all the PCs to Outlook 2010 would cost a fortune.
So we need to find another way round it, can we stop the profile from being upgraded or somehow make Outlook 2007 work properly with the Outlook 2010 profile?
Surely this is a problem that other people have and a cynical person would think that MS have done it on purpose to give people a reason to update.
