Error when only some XP workstations open Office 2010
The Microsoft Exchange Address Book was unable to log on to Exchange. Contact your system administrator if the problem persists.
Some Windows XP with Office 2007
repetitive password prompts
Yesterday before I decommissioned the last Exchange 2003 server all was working properly.
Recognizing that XP is not supported it would be helpful if we could buy some time to upgrade to Windows 7.
Thank you for your time in advance!
