Exchange / Outlook available off site

Any Exchange guru's able to help me with a problem?

 

We have an Exchange 2007 server onsite which for the most part works fine. The majority of staff access their emails via the web interface, however the SLT use outlook 2010 on their laptops.

 

Now, when they take their laptops offsite they can no longer access their emails via outlook (web version is fine) They keep being asked for their login details but it doesnt seem to work and outlook says disconnected.

 

Here are the settings in their outlook account;

Yup, tried all 3 options and still the same as per attached message.

Then i get a disconnected message in outlook.

 

Im pretty sure it was working ok before christmas and the only thing i can think that has changed is the certificate on the exchange server was renewed in January

 

Im using my account to test with at the minute and personal hotspot from my phone
