Restart Outlook and the mailbox will start to sync. Login to outlook email server using SMTP and send. The Exchange cache default setting is 12 months.

If a mailbox has not been converted to the new server, and does not have an associated 'archive' mailbox then this message might be displayed in a folder with email older then 12 months. RRU has an email archive system that moves emails older then 60 days into an Archive folder, so for most people this might not be an issue but the Default setting for Outlook in Cache Exchange Mode is to only download/show 12 months of email. When you click on mailbox folder, you do not see any email older then 12 months and a message below the lowest email says 'C urrently displaying messages newer than 12 months' Background information
