Ever since I updated my Samsung Focus, to Windows Phone 7 (Mango), I’ve been having troubles downloading attachments on the fly from my Exchange account on my server.
Typically I would open an e-mail, click on the attachment, and it would fail stating: Cannot download attachment. A work around I found for this was to hit “Back” hit the sync button, then the attachment would be available. However this was SUPER annoying.
Another feature that didn’t work was to search for items on the Exchange Server.
I did a bunch of research on this and found numerous other people who had the same issue. Their fixes would often temporarily resolve the issue, but typically the issue would come back.
Today; I installed Service Pack 2 for Exchange 2010 on my server. After doing this, I noticed that on the fly attachment downloading is now working, along with searching the Exchange Server.
To resolve this, simply install Exchange 2010 Service Pack 2.
