How do I upload external attachments?
Asked by Polly Nuth:

In the version 1.4.2 of the External Attachments add-on on Confluence 5.8.14, I am unable to upload an external attachment.

Screen Shot 2016-02-01 at 1.36.45 PM.png

In the above screenshot, if I were to enter a "Name" and a URL to a publicly shared (no sign in required) document on OneDrive, pressing the "Upload" button does nothing and "Insert" stays grayed out.

How do I attach external documents to a Confluence page?

author: Milo Test
body: You mentioned OneDrive. Just open your OneDrive folder and drag the file onto the Confluence page.

Keep in mind that neither the attach dialog nor the drag method will maintain a connection to the external file. A version of the file will now reside within Confluence and be completely disconnected from the file in OneDrive.


author: Polly Nuth
body: That defeats the purpose of using the external attachment add-on.


author: Milo Test
body: Did you try the **Get a link** option in the **Share** dialog, to generate a URL to paste into the URL field?


author: Polly Nuth
body: Per my original post, I've tried entering the URL (no sign in required) that was obtained from OneDrive. When I press the "Upload" button, it does nothing.

body: I have and have not gotten a response yet (been about 2 days).

Not exactly sure where the "white list" is, but I am able to configure an "external server" under the configuration for the External Application add-on. This is not ideal since a username is required.

At any rate, adding the external server doesn't make a difference.

Attaching/uploading an external attachment still does not work.

body: I'm talking about the Confluence Whitelist:

Gear -\> General configuration -\> Whitelist (in the USERS \& SECURITY area)


author: Polly Nuth
body: Not sure if whitelisting helped.

I added the url and tested ok. I enabled both outgoing and incoming.

I attempted to add an external attachment and it still doesn't do anything when I click on attach/upload.


author: Milo Test
body: \[Shrugs\] It was worth a try.
