Exchange 2010 OWA – Email Attachments are not opening – An unexpected error occurred and your request couldn’t be handled when viewing emails with attachments only.

OWA – An unexpected error occurred and your request couldn’t be handled when viewing emails with attachments only.

Problem:
Have a Windows 2008 server R2 with exchange 2010. Everything was working fine, however, I installed SharePoint 2010 and then uninstalled it once I realized it stopped OWA from working at all. Since then, everything was back to normal….except one thing. When I log into OWA, everything logs in okay, I can only view emails without attachments. When I click on an email that has an attachment, it gives me an error within the message pane on OWA saying “An unexpected error occurred and your request couldn’t be handled.”

When I look in the event logs I have a particular log that may be relevant (see below event log message). I am not sure how to resolve this….anyone have any suggestions?

Start event log message:
Watson report about to be sent for process id: 6600, with parameters: E12IIS, c-RTL-AMD64, 14.00.0694.000, OWA, M.Exchange.Net, M.E.S.R.P.ProtectorsManager.LoadProtectors, M.E.S.R.Protectors.AttachmentProtectionException, 8b03, 14.00.0694.000.
ErrorReportingEnabled: False

Resolution:
Install Exchange 2010 Roll up 3, and it will fix this problem.

Microsoft TechNet Forum – Exchange 2010.
See the same problem in TechNet Exchange 2010 forum, where on guy was facing the same problem, and the above provided solution, resolved the issue!

    Hi Zahir,

    I’ve seen your comments on the microsoft technet forums re this issue. I have the same problem with attachments, any emails with attachments in OWA 2010 cause problems and go into an endless/prolonged loop if I try to open it.

    In OWA I get an unexpected error occurred on any emails with attachments. The funny thing is attachments were fine and have recently become an issue. If I look at old emails with attachments before the problem occurred, I dont get the unexpected error occurred but I have the same, looping problem opening attachments.

    I have Service Pack 1 and installed rollup 2 as recommended by yourself and others. This hasnt helped in my case, I’ve recreated all virtual directories in hope it may help but it hasnt.

    Not sure what I can do apart from reinstalling CAS. Any advice will be much appreciated.

    Thank you
    Athar

  4. Hi there! This post could not be written any better!
    Looking at this post reminds me of my previous roommate!
    He always kept talking about this. I am going to send this information to him.
    Fairly certain he’ll have a very good read. I appreciate you for sharing!

  5. Howdy! I understand this is somewhat off-topic but I needed to ask.
    Does managing a well-established website like
    yours take a lot of work? I’m completely new to operating a blog but I do write in my journal every day. I’d like to start a blog so I can share my own experience
    and thoughts online. Please let me know if
    you have any kind of ideas or tips for new aspiring blog owners.

    Appreciate it!
