When using ACT! 2010 with Outlook 2007 keep receiving error that Outlook is not default mail client.

Within ACT! 2010 I keep receiving the error:

"Either there no default mail client or the current mail client cannot fulfill the messaging request. Please run microsoft office outlook and set it as the default mail client."

This occurs when trying to send e-mails via Outlook 2007 and sometimes it appears to occur randomly while moving through the ACT tabs.

However, Outlook 2007 is confirmed to be set as the default mail client.

I followed this Microsoft KB article without result:

OS is Windows XP

Any ideas would be appreciated. Thanks!

Does the issue still occur if you disable the Act addin?

This is something I won't be able to test until later today when I am able to remotely access the clients machine. Will removing this addin remove ACT and Outlook integration features, buttons, etc?

Removing the Outlook address book will remove the buttons from outlook yes. But its an easy test to see whether or not the issue is caused by the Act plugin or if its Outlook related.

On another note have you tried running Office diagnostics?

Ok fair enough. I have tried running Office diagnostics.

I am only suggesting that you temporarily disable the addin, this way you can test if Act is the cause of the issue, but yes disabling this addin will remove the integration functionality.

Can you try recreating the mail profile?

If that doesn't work, can you login to Windows as another user and setup the integration with Outlook and see if that works?

I ended up getting it to work. Last time I checked the default e-mail client was set to Outlook 2007, after removing the key in article and running office diagnostic it must have changed it to Outlook Express (therefore appearing the problem had not been fixed). When I again changed it to Outlook 2007 it fixed the issue.
