Can you pull back an email that was sent if it is unopened?

If have sent an email, can I pull it back from the recipient if they have

not opened it yet? How do I do that?

Orland, Kathleen

Open the email. Click on Actions > Recall This Message.

Note that this doesn't always work. If they have opened it or deny the

recall request, if they're on a different mail server, there are many

instances where this may not work.

Recall rarely works across different e-mail servers. It only sometimes

works when both sender and recipient are using the same Exchange server (or

Exchange servers within the same organization); however, if you are sending

e-mails via SMTP, the chance of Recall working is dismal. That means rather

than issuing a recall *function* to the Exchange server to yank out the

original e-mail from the recipient's mailbox, you are sending a *new* e-mail

that requests the recipient's mail client to remove an item AFTER the mail

client has downloaded the original message from their mailbox. That means

the e-mail client must understand the encoded Message-ID header in your 2nd

new e-mail that makes the recall request. It also requires that the

recipient open the recall e-mail BEFORE they open your original e-mail - and

that means the recipient would need to have e-mails listed in descending

sort order rather than ascending sort order. If the recipient opens your

original e-mail (which they WILL already have downloaded) before opening

your recall e-mail then they can obviously read the original message because

they have not first opened your recall e-mail which then attempts (in

Outlook only) to delete the original e-mail.

Even if the recipient reads their e-mails in descending sort order, it is

unlikely that their e-mail client knows how to handle a recall. The

Microsoft-specific non-standard modification of the Message-ID header (by

adding the "!-!" prefix and encoding information within the userID portion

before the "@" character) is used to indicate a recall but it is only

recognized by Outlook (and the recipients have to read e-mails in descending

order so they open your recall e-mail first) so don't expect the recall to

work. A recipient using anything other than Outlook 2000+, like Outlook

Express, will see both the original message and recall messages and first

opening the recall e-mail will NOT delete the original e-mail. Non-Outlook

e-mail clients don't know how to handle the recall request that is encoded

within the Message-ID header.

If using Exchange to send your e-mails which were sent to a recipient also

using the same Exchange organization then recall might work because the mail

server is handling the request to delete messages from the recipient's

mailbox. Recall won't work unless both sender and recipient use Outlook

2000+ and the recipient happens to open the recall e-mail first.

At this point, and if you are the sender, you should send another new e-mail

to correct your mistake in your original e-mail or to apologize for the

content of your first e-mail. Getting a recall e-mail will only draw more

attention by the recipient to your original e-mail.

If you read the help already included in Outlook to search on "recall", it

would have plainly stated "This feature requires Microsoft Exchange". For

SMTP, there is a miniscule possibility that if the recipient also uses

Outlook then the recall via the encoded Message-ID directive will work since

Outlook handles that non-Exchange method. It rarely works.
