My colleague received an email from H company. This email is protected by Microsoft Rights Management Service.
His email client is Outlook Express, and he use POP3 to received it to local disk (the mail is deleted from the mail server). Outlook Express only show a short description about RMS and an attachment named message.rmmsg
. So I Installed an Microsoft Outlook 2010 on another machine, and forward the whole original email (as an attachment – SUBJECT.eml) to his own mail address, and try to read the attachment in Outlook 2010.
At first, I encountered "This service is temporarily unavailable" when connecting RMS server of H company, and after some struggling I found a solution here: uncheck IE->Tools->Options->Advanced->Settings->Check for publisher's certificate revocation and Check for server certificate revocation.
Now, when I try to read this attachment email, Outlook 2010 keeps asking for a Username & Password even if I input the correct mail account of my colleague and password.
What's wrong? Did I inputed usernamd & password of a wrong realm? Do my colleague need to ask the sender for a username & password to read this email? Or, does the RMS protect email from reading from an .eml attachment (I mean, do my colleague need to ask the sender to send the email again?)?
How can my colleague read the email?

I also use my colleague's email address applied an account on RMS for individuals according this article: View and use files that have been protected by Rights Management. But still I got same result (keeps asking for username & password) even if I entered password of either RMS accout or email account.
I use wireshark captured the data communicated between RMS server and my computer, the RMS server returns Encrypted Alert.

Reference Introduction to IRM for email messages:
The message "This service is temporarily unavailable" when connecting RMS server of H company implies that you are unable to get a "use licence". From above:
Content with restricted permission can’t be opened if the licensing server hasn’t issued you a use license for that content
You can use Outlook Web Access (OWA) to view the restricted messages using any browser.
So, you be able to at least view the message using the Rights Management Add-on for Internet Explorer. However this doesn't work for attachments.
