Hello,already in this thread, a problem in Entourage 2004 linked Exchange 2007withAttachmentswerediscussed.http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=2178602&SiteID=17I have installed SP1 for Exchange 2007. SP1 fixed that Problem with broken attachments, which sent external.But now I have another Problem with attachments.If I receive an external mail with an attachment, which is sent from Mac Mail or any other mac mail client, with Entourage (linked with an Exchange 2k7sp1), the attachment looses type and creator (resources forks).You can create a new type and creator, so that you can use the attachment for further use but this is not practicable for production use.it involves any file recieved by the described construction (external Mac mail client -> entourage).I have a exchange 2003 Server in my test enviroment, and have no problems with attachments.I suspect a Bug in OWA of Exchange 2007. Have anybody the same problem? Perhaps have someone a solution to fix this failure?Greetz
