Emailing from the Windows Product - Error Message: No Default Mail Client

I have a Microsoft Office 365 account and Outlook is set as current default on my computer. However, when I attempt to email from MasterCook, I get a message that says:

Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client.

If you are using the 64-bit version of Office, 32-bit programs like MasterCook cannot work with it. See this article.

This happens with other programs and is not specific to MasterCook. For example, this person uses Avast Cleanup and a setting in that program caused their issue. See this discussion:

You will see several things were suggested, and others found those suggestions fixed their same issue.

Otherwise, if you search the internet for your error message as it relates to Office 365, you will find others see the same error, and they are not using MasterCook.

Without knowing what type of antivirus or security programs you have on your computers and the settings used in those programs, it’s difficult for me to know what is causing the issue for you. It could simply be caused by a setting in another program on your computer is blocking MasterCook from accessing the MAPI client on the computer, like Avast Cleanup.

However, the quickest and easiest way to email a recipe is to copy a recipe in MasterCook and paste it into the body of the email and send it. Quick and simple. Or, you can export to a file on the computer and attach that file to an email. See this MasterCook Support article:

This allows you to bypass MAPI and other programs on the computer that are blocking it from fully working.
