In the past week a number of users had trouble using the Sync feature in their Total Access Mailbox software, which allows syncing of the local address book with the Web Mail address book. Users were getting an error "The server is not available. Try again later." If you submitted a comment or question on this issue in the past few days, I didn't publish those while I was investigating the issue.
This problem has been fixed. All users should be able to sync now without trouble.
