Errors sending email in Outllok 2007 after upgrading

After upgrading from XP to Vista busness and from Outlook 2003 to Outlook 2007 I get a error when trying to send email. "Microsoft Office Outlook cannot sign or encrypt this message because you have no certificates which can be used to send from the e-mail address 'xyz@xyz.com'.  You can do either of the following:

Get a new digital ID to use with this account.  On the Tools menu, click Trust Center, Click E-mail Security and then click Get a Digital ID.

Use the Accounts button to send the message using an account that you have certificates for.

There are no certifiactes on the pc and we connect to a Exchange 2007 where the email admin says theire is no certificates.  
It worked fine sending in Outlook2003.  And when you go into outlook 2007/tools.trust center/email security the 'encrpypt contents and attachments for outgoing messages' is checked but grayed out where I cant uncheck. Also everything else under Encrypted email is checked.

Any thoughts.

Thanks

Hello athelu,

Delete and then recreate the account in Outlook 2007.

1. Check if Outlook is in Offline mode. In Outlook go to File and make sure Work Offline is not selected.

2. Register an important send/receive library file.  Go to Start > Run and type regsvr32 inetcomm.dll

3. Check if antivirus email check is slowing sending and receiving.  Disable it. Check if other programs running in the background is interfering. Disable one at a time the Firewall, antispyware, antispam, and all Norton programs.

4. In the account settings, Advanced settings, change the server timeout time from 1 min to 5 min

5. Check if outgoing mail server authentication is required. Select that option in account settings and use same settings as incoming server

6. Your ISP may be blocking port 25. Try using alternate port 587.

If no joy, you need to use your ISP SMTP server to send out emails.

7. Create a new Outlook profile.

8.  Check with email provider Tech Support to determine if server is having trouble.

Hope this helps!

I actually found this that ended up being the solution. It was a registry setting.
