Outlook Web APP Not accessible

[Jackw163]

Hi,

I First off want to admit im a complete noob at all this with only a general grasp of things, i recently switched to a pfsense 2.4.3-RELEASE-p1 router instead of an off the shelf, i have wan connected to a vdsl modem via PPPoE but it is mostly as it comes, i cannot access Outlook web app through the internet since moving to pfsense but most normal internet traffic works fine, i understand im probably doing something terribly wrong but any help would be greatly appreciated, please ask for any more information needed and thanks in advance for any help
