Cannot send email from Outlook due to “Error 0x80070057”

Asked By 0 points N/A Posted on -


I am a Gmail user, and I'm accessing my Gmail account via MS Outlook. My OS is Windows Vista. When I try to send an email in Outlook 2007, I get this error:

  • 0x80070057:

Task [my email address]- Sending' reported error (0x80070057) : 'Could not complete the operation. One or more parameter values are not valid.'

Problem lies on sending mail, not in receiving. Messages that don’t get sent are not placed on Outbox. They are visible from the folder, but don’t go anywhere. I have also attempted to type the email address of the recipient (did not use auto-complete feature of address book), but that didn’t work.

I need a solution here.

Hello Abianderson,
The error about your MS Outlook 2007 is about the registry, the registry is like a memory or storage. Some of these registry keys contain a lot of data. If the registry is at its size limit, these large data entries are not written or it cannot saved the data that is needed.
However the error you must receive states that it is unable to write the data in the registry. To receive the right error. To receive the correct error message from the installer, install MDAC 2.7 SP1.
To download MDAC 2.7 SP1, visit the following Microsoft Web site:
To resolve the size limit problem in the registry, you can increase the maximum size of registry in Windows NT 4.0 and Windows 2000. Just follow the following steps:
1. In Control Panel, double-click System.
2. Click the Advanced tab, and then click Performance Options.
3. Under Virtual memory, click Change.
4. In the Virtual Memory dialog box, change the registry size.
Hope it helps.

Let me first identify your problem:


You are having a code 0x80070057 error in outlook 2003 while sending emails.
This can be due to many reasons:
  • Damaged or corrupted registry.
  • Missing or damaged DLL files.
  • Viruses.
  • Malwares.
  • Corruption of critical system files.
So, first things first. Recover your registry through softwares available on the web. You can benefit from the link (Copy and paste the link into your browser).
if this doesn't work, second thing you should do is get your windows cd and repair your current existing windows installation. Remember Repair, do not reinstall as it will destroy your data. See if this fixes your problem.
Don't forget to use a good antivirus software, for reference sake you can use Avast, they provide their free of cost through their website  and it keeps on upgrading itself. Its good as per my recommendation.
If problem persists, let me know, I still have certain tricks rolled up under my sleeves that we can work.
