Windows 7: Outlook 2010 and sending large attachments

Outlook 2010 and sending large attachments

Not that large actually. The critical size of an attachment is 3Mb; larger than that and the e-mail doesn't leave the Outbox, and I get a send/receive error which means nothing to me at all. What is actually happening is that e-mail is being sent everytime Send/Receive happens, so addressees are getting my e-mail every 20 minutes - and usually phone me when they have downloaded 30 - 40 copies of the e-mail into their In Box, at which point I manually drag the message from 'outbox' to 'sent items'.

Any ideas on what's happening/how to fix (in simple English please)

The above method involves changing the registry - please ensure that you backup the registry before making any changes. You can always restore if the result is not what you expect.

Alternatively, and probably a safer method, you could reduce/compress files with a 'zip' facility, e.g. WinZip. Here are some guidelines:

- could be that your IP has a limit on the size of a message, maybe.. (?)
