MS Technet Exchange forum recently from someone who wanted to be able to open links to non-standard protocols in their OWA. Normally, if you click on a link that isn't http or mailto, you will get the simple message saying ‘This link has been disabled to protect your security.' Normally, this makes good sense, as you don't want your users to click on unsafe links. But what if you really, really need to give them the option to do so? Well, it appears you're stuck. https://support.microsoft.com/en-us/kb/982463 As it happens, I found a way to get round it, but it involves replacing the UrlBlockedError.aspx file wit a cusomised one that shows all the links in the message (along with their true destinations), and then the message itself once more, but with the links restored. First, find your UrlBlockedError.aspx file in C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa . Make a backup copy then http://blog.leederbyshire.com/2013/06/25/reveal-blocked-message-urls-in-outlook-web-access-2010/ open it in Notepad. Delete the entire contents, and replace with the code below: <% @ Page AspCompat = True Language = "VB" %> The URL you clicked was originally blocked by Outlook Web Access. If you are sure it is safe, please review the message below and try again.

Check the type of link they are clicking, see if it's a MIME type that's being blocked. that's in the same menu. hope this helps!
