Using Microsoft Outlook 2010 on a network with a Microsoft Exchange Server 2010. The Exchange Server is the only email address associated with my Outlook. Have not had any problems for over a year, but three days ago my email cache disappeared.
In other words, when I start typing an email address to send a new message, my previously sent email addresses do not list. They will start to re-accumulate all day while I use it, but will be gone again after a reboot.
Has anyone else had this problem?
