As jehon already answered, you can disable the Internet connection for all MS-Office 2013 products (Word, Excel etc...) by using the following
Windows Registry Editor Version 5.00
But for me it was not enough and as some other commented, there was still some more popup appearing when starting e.g. Excel.
This is probably due by the proxy I have to use at work which needs authentication.
The other answer to put that Microsoft URL in the
no-proxy setting is not working if you really need the proxy to browse Internet.
This solution, additionally to the Registry modification (c.f. Regedit script above), is to totally disable the connection by adding the following line in the file
C:\windows\system32\drivers\etc\hosts like this:
I suggest to enter similar entries for all the popup you receive (as long there is a destination address like
officeimg.vo.msecnd.net in the OP.
For me it look quiet now and no more authentication popups appears.
Another way to bypass these popups is to create a shortcut with:
`C:\Windows\System32\runas.exe /netonly /user:proxy.domain\myusername "C:\Program Files (x86)\Microsoft Office\Office15\Winword.exe"`
But each time you execute it you have a DOS Windows which ask you your password for
proxy.domain\myusername and another way to bypass this is to echoing the password like this:
`C:\Windows\System32\cmd.exe /c echo mySecretPass | C:\Windows\System32\runas.exe /netonly /user:proxy.domain\myusername "C:\Program Files (x86)\Microsoft Office\Office15\Winword.exe"`
Solution 2 have many drawbacks:
- You have to make a specific shortcut per application
- You have either to feed the password (2a) at every launch or to create very unsecure shorcuts with your password inside (2b)
Solution 1 drawback is that you will not be able to access the domain you put in the file, but it seems they are only for client application.
For me the Solution 1 seems the best for my case.
