Hey,<br />
<br />
We are using an Exchange 2008 server, and the client machine which is having the issue is an XP client with Office 07 on it. <br />
<br />
When the user is trying to accept a meeting request he gets the following message: &quot;MS Outlook could not complete the operation. One or more parameters are not valid&quot;.<br />
<br />
The meeting does not show on his calendar, the user also reports that this has happened when he tries to send emails at times, not often though.<br />
<br />
Please advice!
