I have appointments in an Outlook 2003 calendar that, when forwarded to other
addresses, get stuck in the Outbox. I get the following error:
"Unable to connect to the network. Check your network connection or modem."

Some salient facts:
* Outlook 2003 SP3
* OS = MS Vista Home
* Mail messages send and receive just fine
* My internet connection is obviously fine.
* D-Link DI-524 router on Comcast cable modem
* *NEW* appointments I create can be sent just fine
* The appointments that get stuck most likely were created on a PocketPC HP
iPAQ and were placed in the calendar via ActiveSynch and/or Windows Mobile
Device Center.

I've seen this problem reported on the web but can't find a solution anywhere!

Thanks!

Jim
