Are your Outlook Express attachments too big?
If your attachments are nearing 10 megabytes or more, then yes they are too big. Many email servers only let messages of 10 megabytes or less through. File encoding also takes up some of this space so I use estimate 7 megabytes is what you’re left with.
One option is to tell Outlook Express to split messages up. There are a few pitfalls here. If the party you are sending to email client cannot recombine the message, you are left with several messages full of junk. If not all the messages come through you are left with junk too.
To automatically split messages:
- Open Tools/Accounts, select the email account you want to change, and click Properties.
- Click the Advanced tab
- Under Sending, click Break apart messages larger than…
- Enter 7000 kb for the break size. This is slightly less than 7 megabytes and is a good approximate number to keep under the 10 megabyte including encoding limit.
- Save your changes.
Splitting is automatic. Test by sending yourself a large attachment.
