SMTP Problem

If i try to send an attachment with an email over approx 100kb i get an SMTP error. The problem exists with either Thunderbird or Outlook 2007.
Thank you

Hi Bunkspubble and welcome to Seven Forums.

What type of file are you trying to send? (.doc, .txt)

Can you send any mail or is it just a problem with attachments? Does it happen with the same recipient or others as well?

Thank you for your quick response people, i can send an email without an attachment to anyone. I can send an email with an attachment less than 100 kb to anyone....any sort of file. I cannot send any attachment greater than 100kb of any file type. It is not my ISP, if i revert to my Vista image all is well. My laptop (Vista) is working well also. There is no error code, just the...check your smtp server.

Go to your account settings. Select more settings then advanced settings. Increase the server timeout value. My default is 1 minute. Then try again.

Also, have you applied the service packs to office? If not, you should.

Increasing the time out has not helped, problem still occurs. An office update will not solve the problem, i prefer to use Thunderbird.
I'm heading back to Vista shortly i think.

Windows 7 x64 Pro
Same problem here...driving me crazy...pls help!

I have a clean install of a win 7 pro x64 on a 1yr old vista Dell H2C. I installed office 2007 enterprise and everything works fine, except emails with attachments over 100kb like this guy is saying. I have tried everything. Also just to clarify it's an exchange email account hosted with Sherweb. I can send emails all day but when I try to email something with a attachment over a certin size bam it just sits in my outbox for ever then sometimes it disappears but never send to the intended recipenent. Also if I start to send a attachment and a regular mail with no attachment the regular mail goes out even while the attachment mail is trying to send.

I am stumped...any sugestions would be appreciated....
Also have tried server timeout and nothing.

Since i've had no luck resolving this problem i've reverted back to Vista. Perhaps SP1 when it come out might fix my problem.

Windows 7
SMTP not working

I've had the same problem!! In Vista everything worked fine. Knowing that Windows 7 doesn't have native mail, I installed Thunderbird. Mail comes in just fine....but can't send anything. Just get an alert that SMTP is not working. So figuring it might be Thunderbird, I reinstalled Outlook 2003.....same problem - no SMTP success.

What's going on here? Is this a deliberate attempt by MS to force users to webmail???
