I have a client who is using Outlook 2003 on an Exchange 2000 Server. This is a migration process they are going through. When we are migrating her over from Outlook 2002 on the same Exhange 2000 Server, using Cached Mode we can only see emails up till 2/11/2004. If we disable cached mode we can see all emails to current date. Any ideas why Cached Mode would stop emails from being sen ? By the way this only affects emails in the INBOX... Could it be a corrupt ost ?
