Exchaneg 2003 and Adobe Acrobat
Posted on 2011-10-31
I'm having some problems with our Exchange server and I'm ready to lose my mind. A few months ago I had a user call me and say that he was suddenly unable to view pdf attachments on his phone. His phone uses ActiveSync to connect to our server. I logged into his account using OWA and I was unable to view the attachment without saving it first. I assume that having to save the attachment first is why he couldn't view it on his phone. I fixed this and all has been good up until today.
Today, the same user calls me and says he can't look at the attachments again. I log in again and he's right. I have to save the attachment first and then I can view it. After an afternoon of troubleshooting I notice that this is only happening under 2 conditions:
1. The sender is using Adobe Acrobat and they are sending the document using the email button from within adobe.
2. The sender must be a user from within our organization. The receiver is always able to view pdf attachments from senders outside the company.
If the sender in this case uses Outlook or OWA to send the pdf attachment then it goes through fine and the receiver is able to view it correctly.
Now here's a twist to the problem. If this same sending user uses Adobe to send an email to someone outside the company then it goes through just fine.
It would appear that Adobe may be forming the email in a way that OWA doesn't like. Without doubt I can repeat this using the email button in Adobe. Also, one user is using Adobe 9 with Outlook 2010 and another is using Adobe 7 with Outlook 2003, both of which are having this problem, and it's repeatable.
Any idea's?? Any suggestions?? Could it be a combination of Adobe and our GFI security software on the Exchange server?
