This info will assist the IT technician:

For IT technicians

The MAPI Fixit Tool provided above restores a default Windows Registry value. If the tool is unable to modify the registry directly, the registry key (String Value) can be created or updated manually.

For 32-bit versions of windows:

Registry Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Messaging Subsystem
Registry Value Name: MAPI
Type: REG_SZ
Registry Value: 1

For 64-bit versions of windows:

Registry Key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows Messaging Subsystem

    The error “An email session could not be started. Please check your MAPI installation.” can occur if you’re not using Microsoft Outlook 2007 and later (32-bit) to send your emails.

    If you are using Microsoft Outlook 2007 and later (32-bit), you can fix this error by uninstalling and reinstalling AccountRight.

    Suggestion: If Outlooks default profile is an exchange profile, then turn off cached exchange mode and use online mode – The attempt to simultaneously access the ost file will crash Outlook, or Myob, or both. Not for good reason, but because MYOB does not involke the outlook object properly.

    Suggestion: If you have Windows Mail, look up how to get rid of it if you can live without it.

    Suggestion: MYOB’s old crude and almost offensive VB script for resetting basic MAPI settings, can help, if you’ve got nothing to lose. Even though outlook 2013 doesn’t use the “Windows Messaging Subsystem” registry anymore, there’s a few other values it does reset which are referred to by other programs and relevent settings copied from them. You can download it from the first solution box here: http://myobaustralia.custhelp.com/app/answers/detail/a_id/9229/~/fixing-email-issues-in-accountright

    Suggestion: Reset your program defaults for e-mail: Control Panel -> Program Defaults -> Highlight “Outlook – Desktop” -> click “Use this program as default” – You can double check this by clicking underneath that option where it says “Choose defaults for this program” and confirm down the bottom, under MAPI – Sendmail Command, that your blue Outlook icon is ticked.

    Note/Suggestion: If you have access to “Office 2013 Professional Plus – Retail” installation media, this can actually be activated with a valid Office365 subscription, but it installs completely as a standalone product, and not in the click-to-run bubble.

    Note: In control panel, note that if you have an option for both “Mail (32-bit)” and “Mail (Microsoft Outlook 2013/2016) (32-bit)”, then you need to pay particular attention to which one handles the default. If you only have Mail “(Microsoft Outlook 2013/2016) (32-Bit)” as an option, then you are running a virtualized Outlook and you may benefit from installing Office 2010 (de-selecting all components except outlook) side-by-side, for the sake of silly old MYOB.
