Hi,

We are currently moving from Exchange 2003 to 2007 (8.2 build 176.2).

We have encounted an issue with one user.

In Outlook 2003 when getting a meeting request:

"Can't open this item. Could not complete the operation. One or more parameter values are nto valid."

The item cannot be previewed in the reading pane either.

The item can be viewed in OWA and iPhone fine.

I've tried with cache mode off and on. Different computers. Same issue.

There are the following entries on the account:

SMTP [email protected] [email protected]

X400 C=AU;A= ;P=Company Name;O=Exchange;S=LastName;G=FirstName;

I'm loathe to recreate the account. This will be an extreme last resort.

Any ideas?

Thanks in advance.
