- Outlook For Mac 2011 How To Read A P7m Attachments
I have a customer with a Small Business Server 2008 based network. The majority of the users are on Outlook 2007, some are on 2010. Recently people are running into strange issues where they are unable to open attachments in Outlook on their computers.
In Outlook if you are looking at the inbox, the paperclip shows up indicating the attachment is there. But when you actually open the message up, the attachment doesn't seem to be visible at all. But, if you forward that message to someone else, the attachment will be there.
If you log in to OWA, you can view/save the attachment just fine.
See example screenshots:

I even set up a user's email on a completely different computer for testing, and the behavior was the same. In this case, both computers had Outlook 2007. On another system I tried upgrading Office to 2010, but the behavior was the same. Some users have problems with emails/attachments from one particular sender, others have had it happen pretty randomly.
I'm really stumped on what could be causing this. Is there something wrong with Exchange that could somehow be doing this?
This customer uses Postini for spam filtering, is it possible they could be modifying the messages somehow in transit and causing this?
Anyone have any ideas? I'm frustrated and not getting anywhere trying to figure this out.

The recipient recieves the email and can read the body of the email however the attachment originally sent is replaced with a file named smime.p7m (not.p7s which would imply that is was signed.) These recipients are getting thier emails through different mail clients, mostly outlook or othe SMIME compatible clients. ' (Windows 10) or 'Windows cannot open this file' (Windows 7) or a similar Mac/iPhone/Android alert. If you cannot open your P7M file correctly, try to right-click or long-press the file. Then click 'Open with' and choose an application. Programs that open and convert P7M files: PKCS #7 MIME Message. If you send a message with an attachment and Outlook won't let you send it because the attachment exceeds some limit, adjust the Outlook attachment size limit. Set the limit to match that of your email server so emails don't bounce back as undeliverable. Making this change helps avoid unnecessary Outlook errors, too. Office for Mac 2011 has a number of limitations compared to Office 2010 for Windows. It does not support ActiveX controls, or OpenDocument Format. It also cannot handle attachments in Rich Text Format e-mail messages sent from Outlook for Windows, which are delivered as winmail.dat attachments.
