Zoho Books can't send through your Microsoft 365 mailbox directly, and Microsoft is retiring basic SMTP sign-in for Microsoft 365. We send your invoices through Outlook with a secure Microsoft sign-in, so they come from you and land in your Sent Items.
Customers see invoices from you@yourcompany.com, and replies come straight back to you.
We use Microsoft's secure sign-in, not a stored mail password that stops working when Microsoft turns off basic SMTP.
Every invoice shows up in your Outlook Sent folder, so your team can see what went out.
One secure click. We only use the invoices you send.
Sign in with your Microsoft account. No passwords stored, no IT project.
