Endpoint Protection

Starting to get clients reporting that they can no longer open URLs sent in email messages via Outlook.  When they click on a URL in Outlook, they receive this error "The operation has been cancelled due to restrictions on this computer".  We do not have any GPO restrictions in place, and we don't have any policy setting in SEP that would accont for this as far as I can tell, and its not happening to everyone.  I am going to try removing the SEP client to try to evaluate if SEP is the cause.  Anyone else run into this?  It seems that the majority of online articles I am finding regarding this issue talk about IE in particular with a corrupt registry key, and sometimes IE not being the default web browser.  I have checked both of those issues and reset everything and thats not it, still having the problem.

if you have Outlook auto-protect enabled.

Not sure this applies as we are running client version 11.0.5002.333 which is RU5.  Checked to make sure, Outlook plugin is installed and enabled, and also enabled in the SEP policy...

try unchecking it..see it the links open after unchecking it..

Ok tried that, didn't fix it.  This is outlook 2007, so I went into the trust center, under Exchange client extensions and unchecked the Symantec Antivirus Outlook Protection item.  Closed outlook and then re-opened, still could not open a URL from an e-mail and got the same error message.  Does that mean that the problem cannot be SEP?

Thats right..its only Outlook autoprotect in SEP that interferes with outlook so if isn't doing it then most probably its not because of SEP..

However still you can disabling or un-install SEP and re-testing the URL's

Usually you don't see the "The operation has been cancelled due to restrictions on this computer" message come from programs on the computer, but from configurations in the Operating System (or in this case Office as well).  I'd check to see if somebody's been modifing the group policy settings on that computer or in your Domain if you use one.

Ok well thanks for all the input!

Basically I've ruled out the following:

* IE as default browser
* Symantec EP client
* Specific DLL registration related to Outlook
* local or domain GPO settings

I'm really scratching my head on this one.  I also just noticed that the computer gets an Event ID 27 "the operation failed" for Outlook when the error message pops up after clicking on a URL.  I've tried everything that comes up in my searches for these issues but haven't found a fix yet.  I guess I can try to create a new profile for the user or remove and re-install office as a last resort...what a pain!

Brian81, yep tried that too, with Mr. Fixit and the manual fix.  Still no joy.

Hmm, interesting. I've got to believe it's a reg hack somehwere though. I had the same issues with Word, Excel, and Powerpoint. Was a quick reg fix and it worked. I'm a little surprised with this one. I'll keep looking.
