Hi All, 

I have added a directory within the skydrive public folder whose contents I wish to share with a number of specific people by sending personalised links.

I specifically want to use this method; as opposed to a global link, so that individual permissions can be managed for these recipients. For example, modify view/edit and remove perissions.

I have successfully created and sent the share link to a recipient.

When the recipient click on the link in the in the email their browser opens at the shared directory on skydrive.

The problem occurs when they click on the shared file to download it.  They are taken to the sign in screen and cannot proceed with the download unless they sign in.  The problem with this is that they may not have a microsoft account and I do not want to force them to create one just to gain access to download the file.

I have uncheck the "Require everyone who accesses this to sign in" option.

So my question is this.

Is there a way of sending personalised download links which do not require a microsft account to acutally download a file.
