Description

Don't worry, if you see this message when emailing a layout in Sage 50 Accounts v28 or above using Microsoft Outlook, it's easy to fix. Let's take a look.

Resolution
NOTE: If you have other issues or error messages when emailing your layouts, or if you use a later version of Outlook, you can follow the help in our Troubleshooting email issues guide.

Check your version of Microsoft 365

If you're using Microsoft Office 2010, this isn't compatible with Sage 50 Accounts v28 or above. You should upgrade Microsoft 365 to a more recent version, then try emailing your layout again in Sage 50 Accounts.

If you're using Microsoft 365 2013 or 2016, follow the steps in the section below to resolve the error.

TIP: To find out the version you're using, please refer to the Microsoft help guide >
