Let's get your emailing issue sorted out for you, MauiGuru. Rest assured that I'm here to direct you to the right support in resolving this. 

Based on the error message, it looks like the Microsoft Exchange information service in your profile is missing some details. With this, I'd suggest contacting the Microsoft Support Team. They can help fix the error that blocks the program from sending your emails. Also, they can assist you with changing your profile to ensure that you're using the accurate Microsoft Exchange information service. 

Once resolved, you can now send your sales forms to your customers through the software. 

As always, I'd suggest visiting this website: Email Sales Forms. This link provides you steps on how to send forms by batch, edit, and remove an email in QuickBooks.

I'll be right here to help if you need anything else. Have a great day, MauiGuru.
