Are you running Acrobat 9.2 or later? This was the first version to support Windows 7.What email address is listed under Edit > Preferences > Identity in Acrobat?
Is the email address mesadunes@charter.net in your Acrobat Identity Preferences (Edit > Preference > Identity)? If so, this will be the one that Acrobat accesses when using the Form Distribution Wizard.
This problem has come up in other forum and it's believed to be a bug in Lotus Notes. One workaround was to put a space next to the comma after the address.
