Outlook cannot connect to Exchange

I have an issue if I try to work from home. My work laptop connects to my home Plus.net adsl fine and I can access the internet. I can connect to my work network and authenticate however I cannot use Outlook. Outlook just sits with a 'Trying to connect to Exchange' message. If I log on from my sisters home network I can use Outlook for my work just fine so I know the laptop and accounts are all fine.
This used to work previously from my home but seems I have had this issue for at least the past 6 - 12 months; I'm unsure when it first started as I don't work from home often. I have tried putting the laptop in the DMZ on my router, restoring my router to factory defaults and even tried a different work laptop but the issue remains.
I'm wondering if there are any ports blocked by Plus.net that would be affecting this? I don't have any other issues with my home broadband and most other services work just fine when I am connected to my works network from home such as MS Lync, remote desktop to servers etc. so this appears to be specific to Outlook & Exchange.
Any ideas?

What is the Plusnet Firewall set to?

Re: Outlook cannot connect to Exchange

Thanks for the help. I tried another router and Outlook was working fine so seems to be some issue with the router. Not sure what as I factory reset it and I still had the issue.

Yup. Time to buy a new router methinks.

The page which I linked you to should spew out info which could be helpful troubleshooting, so any more issues try that.

Re: Outlook cannot connect to Exchange

Thanks but all the settings are tied up in the works Win7 build. Besides, if a vanilla router doesn't work then I suspect it is a compatibility issue between the laptop hardware and the router. I tried a replacement laptop which was the same make and model and the issue persisted. I never had the issue with the previous laptop which was another make.
