Accessing archived mails by clicking on "VIEW THE ORIGINAL ITEM"

Hi All,

We are trying to access the archived mails from the link VIEW THE ORIGINAL ITEM.

Whether it is possible to access the archived emails by clicking on the link (as shown in the below screenshot) and access the archived mails from outside the network.

We can open the archived emails form inside the network but using outlook anywhere we cannot able to access it form outside the network.
