Hello there,
I can provide some insights regarding your query about sending invoice emails using Office 360 in QuickBooks Online.
It is true that currently, QuickBooks Online does not support sending emails directly from an Office 365 email address. QuickBooks Online allows you to send emails from a generic QuickBooks email address or a Gmail address.
Yes, there are third-party solutions available to help facilitate sending emails from an Office 365 email address within QuickBooks Online. These third-party apps or integrations can bridge the gap and enable you to use your Office 365 email address for sending invoices. You can go to your Apps menu in QuickBooks or use this link to find one: Apps help QuickBooks run better
By setting up these integrations, you can configure QuickBooks Online to send emails using your Office 365 email address.
If you need further assistance or have any more questions, please feel free to ask in the comment section. I'll always be here to assist.
