If you are using a computer in an educational institution or a corporate environment, you will eventually run into an error message stating that VMOaddin Has Fired an Exception whenever you open Microsoft Outlook. Below, we will show you the cause and how to prevent (not hide) the message from returning. Fortunately, I have not received any reports that users cannot start Microsoft Outlook or that they received the Microsoft Outlook Test Message but users will always see the annoying error message when Microsoft Outlook is accessed until they apply my fix.
It’s My Work Computer
Use the web browser or telephone to contact your IT Department for assistance. They will help you to fix the issue remotely, in person or tell you what to do over the phone.
It’s My Personal Computer
Use the tips below to solve your issue if you feel comfortable. The steps has no undo feature but is safe to perform on your computer.
The Cause
As you can see in the short video, the issue is being caused by the Cisco ViewMail for Outlook plugin and you are most likely encountering it as any version of Windows 7 has now reached its End of Life (EOL) so you have upgraded to Windows 8, Windows 8.1 and Windows 10 to protect your customer’s data and intellectual property from theft and ransomware.
With the plugin for Outlook removed, you will now need to reinstall Windows Media Player if you have it disabled or install VLC Player and make it the default for your attachments containing the voice messages. I always encourage my Windows end-users to go with the VLC Player as if they (usually the Marketing Department) have to access a shared folder on the network to access multimedia content, the player can handle it as it has an extensive library of codecs saving me another trip and call for support.
