How do I take back a message in Outlook2000, in order to prevent a recipient

from reading it? I sent a message to someone in regards to a new account for

work and it went to the wrong customer, so I need to recall that message

ASAP. Any help would be appreciated!

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, you are

sending e-mails via SMTP, not Exchange. 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. That is not your case. You are using SMTP from

your e-mail provider to the SMTP host of another e-mail provider.

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,

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 Message-ID directive will work

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

Now you'll have to send a CRITICAL e-mail to the correct recipient and

warn them to *immediately* change their login credentials, like the

password at a minimum. Or you should change the login credentials

yourself using a randomized password and e-mail that to the recipient

(although that isn't secure so maybe they should call you).
