I am using the IGWPhoneMessage8 GetMIME to retrieve the MIME content for a Phone Message. The MIME however does not have all the header properties such as X-Gwphone-Options, X-Gwphone-Number, X-Gwphone-Company, etc.. In other words all X-Gw* properties are missing.

If we save the MIME using GropWise 8 Client, then we can get all the properties.

Please let me know what causing this.
