Outlook blocked by router

First Timer

Outlook has stopped working only on the home network.


If I connect via hotspot and 4G, go to a cafe, anyone elses wireless there is no issue. 


As soon as i connect back to the home network Outlook won't open - just gets stuck on the 'loading profile' page

Hi @mikedom 


There was an issue last year with Outlook stuck at the loading profile stage.


If there's something impacting Outlook but only via the TalkTalk broadband connection then it's likely to be related to Homesafe. To troubleshoot you can test with the workaround of using a different DNS setting in the router.


Try the secure Quad9 DNS: Primary and Secondary or Google DNS: Primary and Secondary (or a combination of Quad9 as Primary and Google as Secondary)


To change the DNS settings in your router, follow these steps:

  • On a device connected to the router
    Open a Web browser, type into the address bar
  • Tap Enter/Return
  • Enter the username and password and click OK
    Note: The default username is admin (all in lower case).
    The router password is printed on the label on the back of the router.
  • HG633 router password - top of the label
  • DSL-3782 router password - middle of the label to the left of the bar-code
  • Sagemcom FAST 5364 router password - under the pull-up wireless password card on the label directly above the S/N barcode.


For the HG633 router

  • Select Internet (top blue bar)
  • Select Internet Connection and then the grey Edit button
  • Scroll down and tick the Static DNS box
  • Enter the preferred Primary DNS numbers
    Enter the Secondary DNS numbers
  • Click the Save button
  • Scroll up and click Logout (grey button top right)


For the DSL-3782 router

  • In the Web browser address bar, type
  • Tap Enter/Return
  • Tick 'Use the following DNS Server Address'
  • Enter the preferred (Primary) and alternate (Secondary) DNS addresses
  • Click the Save button


For the Sagemcom FAST 5364 router

  • From the Dashboard
  • Select See internet settings
  • Select Manage advanced settings
  • Select the Internet Connectivity icon
  • Select IPv4
  • In the DNS drop-down box select Manually Specify DNS
    DNS1 enter the Primary DNS
    DNS2 enter the Secondary DNS
  • Click the Apply button


If you subsequently choose to return to the TalkTalk DNS the numbers are and OR and

Hi @Gondola 


Genius! That worked!


It appears kidssafe keeps being turned on in the background. I have had loads of issues with it blocking apps, etc. even when you add them to a white list.


Changing the DNS has worked.


Thanks for your help

Hi mikedom 


Changing the DNS will bypass HomeSafe / KidsSafe and so as long as you are happy not to have the security that Homesafe offers then you'll be good to use an alternate DNS.


An out-of-the-box Outlook would not be blocked by Homesafe so I expect there will be an Outlook Add-in that's the root cause of the blocking. 


If you wish, you could continue troubleshooting by restoring the TalkTalk DNS and selectively unticking Outlook Add-ins until you find the one that causes the loading issue. The most likely one is a social media related Add-in that is being blocked by KidsSafe.
