I am trying to publish OWA using ISA2000 on its own URL on an internal non-standard port. Destination sets has been created. Publishing rule has been created. When I try and access OWA externally I get the two main frames but the pages are showing ?The page can not be displayed? error. This is because OWA is trying to be too smart; it is adding the non-standard port into the page address: http://outlook.domain:non-standard port/user/onbox???.. Externally the non-standard port in the address is not relevant and therefore causing the porblem. Internally this works fine as the client can access the non-standard port and OWA is fully functional. I have got around this problem by using Link Translation in the publishing rule: outlook.domain:non-standard -> outlook.domain OWA now works fine except for a couple of functions (2 that I have found so far). Delete, the error is: Some items could not be deleted. They were either moved or already deleted, or access was denied. Move, the error: Outlook Web Access does not currently support this type of move/copy action. In conclusion: I need to get delete & move working with Link Translation or stop OWA adding the port to the address and therefore eliminating the need for Link Translation. Can anyone PLEASE HELP. Sorry for the self taught idiot explanations.
