Outlook For Mac 2011 How To Read A P7m Attachment

Posted on by

This is due to Outlook decrypting the file in RTF format. To avoid this issue you may change your Outlook settings by following these instructions:

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. If your code is working with Outlook and/or OWA and is only failing with the MAC, shouln't you be pinging Apple about this issue with the MAC?.ICS can be added as attachments for a messages, which is a supported operation in Microsoft's eyes. Howevever, custom generated.ICS content (creating the file content without a Microsoft API) is not.

  1. Open up your Outlook email client.
  2. Click on File located in the upper toolbar.
  3. Select the Options setting.
  4. From here, select the Mail category.
  5. Now, under Compose messages, you want to ensure the HTML or Plain Text option is selected for the Compose messages in this format.
  6. Next, under Message format, set When sending messages in Rich text format to Internet recipients to Convert to HTML format or Plain Test format
  7. Click OK to finish

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:

http://1966ford.com/image_hosting_temp/email2.png shows the attachment is there
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.
