1. Start
SyncCell and click 'Settings' from the menu buttons
on the main screen:

2.
The 'Settings & Options' dialog
window will appear. Click the 'Calendar (Advanced)'
configuration tab at the top of the 'Settings
& Options' dialog box:
3.
Locate the 'Advanced OneSync Settings'
section on the 'Calendar (Advanced)' tab of the
'Settings & Options' dialog window. This section
allows you to configure advanced calendar options
including how manual phone calendar entries are
handled and syncing across multiple computers.

You'll notice that there are two
option check boxes in the 'Advanced OneSync
Settings' section. "Write new device
entries to client during OneSync" is unchecked
by default and "This is my Primary Computer"
is checked by default. We'll look at each of these
options in turn in the following steps.
4.
"Write new device entries to client during
OneSync" - Use this option if you have
Calendar Events in your mobile phone that you
have manually entered and that you wish to have
copied into your Outlook Calendar. Note that if
you use this option your phone should only contain
Calendar Events that were created by SyncCell
or by manual entry, otherwise you may end up with
unwanted duplicates appearing in your Outlook
Calendar.
If you want to use this option with
multiple Client calendars, please note that it
only transports ADDS across to the Client Calendar.
It does not transport DELETES or UPDATES and is
not intended as a mechanism to sync multiple Client
Calendars with each other.
5.
"This is my Primary Computer"
- Check this option if you want to sync Client
Calendars from multiple computers to your phone.
The most common use of this option
is when using two different computers, each having
their own calendars. For example, a Work computer
and a Home computer. In this section, the Work
computer should be set to Primary, and the Home
computer should be set to the letter "C"
(or any unique letter).
This setting can be used with any
number of computers.
For example, on your Work computer
you would leave the "This is my Primary
Computer" option selected, but on your
Home computer you would un-check the option and
then select a unique letter for your Home computer.
Un-checking the option causes the letter selection
control to appear as the following screen shot
demonstrates:
