SAGE 50 Email Integration Woes

Sage 50 is a pretty common app in Canada for doing small business accounting. However, one of it's major drawbacks is really poor email integration. I think they've improved it somewhat in recent versions, but there is a MAPI dependency.

If you install the 64-bit version of Office, then Sage 50 will not be able to use Outlook to send messages. Now that 64-bit Office is the default for Office 365, you need to watch for that as step one. However, yesterday, on a new install of Sage 50, it wasn't working even with the 32-bit version of Outlook.

We got the error:
Sage 50 cannot communicate with your e-mail program. Please ensure that your email program is MAPI-compatible and that it is the default MAPI client

You also need to have Outlook configured as the default mail program. The Mail program in Windows was configured as the default. So, we changed that to Outlook. Still no luck. Same error.

The final fix for me was adding a registry key. According to a few people in discussion forums, without that key, Sage 50 doesn't load the mapi32.dll that's required to send email. Silly that this is still happening.

In the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows Messaging Subsystem, I needed to create a new String Value (Reg_SZ) named MAPI with a value of 1.

Some of the web pages I reviewed during troubleshooting:


  1. Hi Byron,

    Thank you for your post., Outlook 365 or the desktop versions (in 32 bit and 64 bit) are tested and supported as of the 2016.3+ (with the Hotfix). Which version of the software were you having this issue with? Note that Sage 50 Office 365 support for the Canadian Edition is available at 1888-522-2722, choose option 6.

    If this issue reoccurs please reach out via a post on this blog (on the subject):

    In the meantime, I'll work on updating the content.

    Warm Regards,

    1. Thanks for the info. This was an older version of SAGE 50 (2014). I'm pleased to see that there are updated options for mail integration in newer versions.
