Windows Mail 'breaking up' messages sent with larger attachments
Posted on 2009-12-23
A friend is having some trouble sending larger attachments using Windows Mail.
I am logging in remotely & trying to assist them.
They can send a normal email, without any attachment.
They can send an email with a ~30KB attachment.
But when trying to send an email with a ~2MB attachment the following happens:
It appears that Windows Mail splits the message up into 'parts' (55 in this particular case).
The send/receive box reads 'Sending message 1 to 55 (part 1 of 55)'.
There is only this one single message in the Outbox.
After it reaches about part 15 of 55; it gives a Server Error 451: Too many messages sent within certain time period. Error code: 0x800CCC6A
The 15 parts that did manage to send then end up in the recipients inbox as separate messages & the original attachment is no where to be seen.
I have done some research & found that Norton products are commonly incompatible with Windows Mail. I have tried disabling all their Norton services & testing it then, but with no luck. Before I remove Norton software completely; is there anything else I can troubleshoot or try...?
Thanks in advance for any help or suggestions.
