On my Cingular 650, I use VersaMail and Microsoft ActiveSync to access my corporate e-mail and calendar items in Microsoft Outlook.

My e-mails have been synching well via wireless. Items sent from my Treo show up in the Sent folder on my desktop.

However, on the Calendar, I just noticed that whenever I enter an item on my Treo, it does not show up in my desktop Outlook Calendar after wireless synching. The converse is not true. Items entered onto my desktop Calendar do show up on my Treo Calendar after wireless sync.

Can anyone help on this issue?

Thanks in advance.
