Working with Attachments in P.O. Box

If you have the ability to post to a list, you have the ability to share files (attachments) with list members. Please note that the files are not emailed to the list members. Instead, list members retrieve the files by either following a link in a P. O. Box email message or by logging into the P. O. Box service directly.

Note: There is a maximum of 100 MB per attachment, and a maximum of 200 MB for all of the attachments associated with a single message.

Retrieving Attachments

In order to retrieve an attachment, you must log into the P. O. Box service. There are two easy ways that you can download an attachment from the service.

• Each e-mailed P. O. Box message will contain links to any attachments included with the message:
  
  
   
  1. In your e-mail program, click the link for one of the attachments or cut and paste the URL into your web browser.
  2. When prompted, provide your UDelNet ID and password to log into the P. O. Box service.
  3. The file should download to your computer automatically after you see the Attachment Download page.

• If the download does not begin automatically, click the link labeled "try clicking [here]."

4. After you have downloaded the first attachment, click each link for any other attachments. Since you are now logged into the P. O. Box service, you will not need to login again, but you will see the Attachment Download page.

• You can always log into the P. O. Box service to retrieve a message and its attachment(s).
  1. After you've logged into the P. O. Box service, select a list and then click Messages/Actions.
  2. In the Messages: area of the next screen, click the magnifying glass icon next to the message whose attachments you wish to download.
  3. Click the down arrow icon next to each file you wish to download.
