Missing location information
 

I've sent a user a meeting and type in information in the location field.
When the user sees my meeting request the location field is blanked out.
We are using exchange 2003 sp2 in a corp. environment.

The problem just started showing up and all the meeting requests are missing
location information when the user receives the meeting request.
The sender of the meeting when looking in their caldendar has the location
information.

Any thoughts on how to resolve the problem??
