Problem with word.activedocument.save at secure urls

[atlantitian]

Hi,
Pardon and redirect me if this is not the correct group.

We need to save a word doc to a server url. We have written a macro
which uses word.activedocument.save to save it. I know this needs front
page extensions to be installed on the iis and we have ensured its
presence. We are able to save to server when url is simple http -
however it fails with error:#5096 when the url is https.

Does word.activedocument.save have any limitation? Is there any
solution/workaround for this?

Thanks,
Piyush
