If you need to schedule a meeting with people who use Outlook,
Pocket Outlook, or Schedule+, you can use Calendar to schedule
the meeting. When attendees receive a meeting request, they can
accept or decline the meeting. If they accept, the meeting is
automatically added to their schedule. In addition, their response
is automatically sent back to you, and your calendar is updated.
Before you can send a meeting request, you need to enter e-mail
addresses in Contacts and set up Inbox to send and receive
messages. For information on using Contacts and Inbox, see
"Tracking friends and colleagues" on page 70, and "Using Inbox"
on page 61.
To create a meeting request
1. Tap Tools, Options, and then select a mail transport. If
you send and receive messages using synchronization,
select Windows CE Inbox Services. If you connect to
an ISP or network, select the service you set up in Inbox.
2. Tap File and then Make Meeting.
3. Enter the meeting information.
4. Select the contacts you want to invite.
5. Select other desired options and then OK.
