mpeg file too large to email--recipients email's returned undelive

Hi, this is Windows XP system and I use Outlook as my default email client. Yesterday I sent a mail to few people with mpeg video attachment recorded with my digital camera. Today I found that email returned saying "too large a file" to be received. What does that means? File is very small in size and I have sent files with larger size than this in past. Is it because of the file format? I think converting the file and sending it in .wmv format not create any problem? What you guys think?

Nope, thats not the problem of file format. It is surely the email service or email client because most of the email service wont support an attachment with specified maximum limit of size in mbs. You should better try sending the larger files through an online service called yousendit.com.

Thank you very much for the help Vanilla. I will surely that online service when i reach home.

Help appreciated.
