Outlook 2011 on Mac Sending Error with Attachment

I have a user that is running OS 10.7 and Microsoft Outlook 2001 for the MAC. When the user tries to attach anything over about 2Mg, sending the email errors out and is sent to the drafts folder.

This is the error and message:

Help with this error: Error code –18596
Http error. The resource is not found

Mail could not be sent. The message has been moved to your Drafts folder.

Account name: "Dave"
      Outlook 2011

I have tried this solution but the exchange server doesn't have the appcmd.exe anyplace in the system


Does anyone else have an idea on how to fix this?

What is the domain you are using? An exchange or IMAP? Public? Etc.

With exchange server 2007 make sure that your default attachment size is not 2MB. Also you may want to recreate the user's account. Do this by quitting outlook and going to Documents > Microsoft User Data > Outlook 2011 Identities and deleting this entry. from there when you open outlook it will start with a new identity.

I have made sure the 2007 exchange is at 30meg as I can send that much from a windows system.

I have also tried to recreate the users account for outlook and am now recieving the follwoing error when sending larger files.

HTTP error. The resource is not found.

Mail could not be sent. The message has been moved to your Drafts folder.

Account name: "Company"

Error CodeL 18596
