Dear Jared,

Sorry for the delay. I have tried until the step 3 mentioned in the article that you gave me without any success.

We were previously using Office 2010 in our computers, so does that step 4 is really valid? Please note that whenever i am connecting to open internet O365 activation is working fine. Hence the activation is being blocked by our office security measures(Cisco firewall or MS TMG server).

When we are connected to our office network, even though the computers are having internet there will be a mark on network access 'no internet access' will that really affect on office 365 activation? Let me know your comments.

Hi Livin,

Since you were using Office 2010 in your computers before, the Step 4 from the article is no need to attempt.

Based on your description, I understand that Office 365 activation is working fine with a typical open network connection. Regarding” When we are connected to our office network, even though the computers are having internet there will be a mark on network access 'no internet access”, I’d like to confirm that whether you can access the outside network resource under ‘no internet access’.

Besides, it will affect Office 365 activation without a good internet connection, because each time when the user logs on to their computer, the computer connects to the Activation and Validation Service to verify the license status. This is the outside resource against the resource inside your organization.

So, I suggest you include the URLs of Office 365 authentication and identity in your outbound allow lists to ensure these computers can successfully use Office 365. Please refer to the authentication and identity section for detailed information in the following article.

Office 365 URLs and IP address ranges

Yes it certainly will. Office 365/CTR (Click to Run) is MUCH more sensitive to network connections than Office 2010 was for installation and ongoing running.

When CTR was first introduced in 2010, MS has a series of what I called "stupid install stunts".  With a GOOD Wireless network connection they were able to install in various absurd situations:

• parachuting
• in a race car
• in a speed boat
• etc

But, since then more and more people have reported installation and activation problems that were eventually directly related to network connection issues. One of the tests has been to, as you have done, use an alternate network connection to see if the problem is specific to your original network.  While that was OK for Office 2013 1-time payment licenses, it is not workable for Office 365.

I have collected all of the "network connection" related fixes I've seen reported into a single Wiki.  Browse through it and see if you can find any of those fixes that are relevant to your situation.

"Official" MS documentation of error codes, gives you error message text associated with error code if you don't already have that, but nothing more

Hi Livin,

Any update would be appreciated.
