I am using Microsoft Exchange ActiveSync, but the last seven
days of email messages and Calendar events are not downloading
to my smartphone
Check with your system administrator to obtain the name of the mail server that offers
you wireless access to the corporate mail system. If you cannot obtain the name of
this server (some companies do not give it out, because they do not want wireless
access to their servers), you cannot synchronize email messages and Calendar events
with the server using Microsoft Exchange ActiveSync.
