cannot emailing the reports in QuickBooks 2015

Hello Nana0720,

Thank you for reaching out to the QuickBooks Community. There are a few things I'll like for you to verify. First, I would like for you to check the settings in the webmail preferences.

1. Go to the Edit tab, then choose Preferences.
2. Click Send Forms.
3. Under My Preferences, select the current email account. 
4. Click Edit.
5. Mark the SSL box, or just select Default.
6. In the Server Name field, ensure it's the same as your email provider.

If all those settings are accurate, the next step would be to reset your email service in the program. In the same Send Form area, click delete to remove the email. This article shows how to connect your email once again. Keep me posted and let me know if you've any additional questions.

We already check the setting in the webmail preferences previously. But still unsuccessful and didn't solve my problem.

Thanks for keeping in touch with us here in the Community, @Nana0720.

I appreciate you for doing the steps suggested by my colleague @SashaMC.

I suggest saving the document and send it outside QuickBooks. Here's how to save it as PDF:

1. Go to the Reports menu then click Company and Financial.
2. Select the specific report and choose Save as pdf under the Print drop-down ▼.

Once done, you can send this outside QuickBooks.

Meanwhile, you'll also want to customize your reports in QuickBooks Desktop: Customize Reports in QuickBooks Desktop.

Please let me know how it goes in your end by leaving a comment below. Take care and have a good one
