How to create URI Scheme to open local Google Voice App when clicking google voice mail links in Outlook

Question

Hello,

I'm trying to enable a google voice mail link from Outlook to open the local google voice app instead of opening voice.google.com via a browser. I've been trying to follow steps in link below but this is a bit over my head. I've spent some time trying this but thought i'd post this here to keep my sanity.

Back story: I've migrated a tenant from google workspace to O365. The tenant has a google voice line that's associated with a specific mailbox to receive voice/sms messages. The google voice line has been moved/re-associated to mailbox@Stuff .com since the domain is now hosted with Microsoft. I've setup forwarding of all emails (voice/sms) from the gmail.com account to the O365 mailbox. All is working except Group SMS messages. The sms messages are transcribed to text then readable in Outlook. The problem is it only transcribes the last SMS message. In order to read the sms group history, the user can click the Google Voice link attachment from Outlook, which opens a web browser. Since the end-user is logged into their O365 account often, their having to login to the google voice mailbox every time. Having the clickable link open the locally install google voice app will save lots of time.

thank you in advance,

There are a few different ways you can try to set this up. Here are a couple options:

If you have the Google Voice app installed on your computer, you can try creating a custom protocol handler that will open the app when you click on a Google Voice link in Outlook. To do this, you'll need to create a new registry key with the following steps:

1. Open the Start menu and search for "regedit" to open the Registry Editor.
2. Navigate to the following key: HKEY_CLASSES_ROOT\gvoice\shell\open\command
3. Right-click the "command" key and select "New > String Value".
4. Name the new value "URL Protocol" and set its value to "".
5. Right-click the "command" key again and select "New > String Value".
6. Name the new value "Default" and set its value to the path of the Google Voice app on your computer. For example, "C:\Program Files\Google\Google Voice and Video Plugin\GoogleVoiceAndVideo.exe" "%1"

Once you've done this, Google Voice links should open in the app when you click on them in Outlook.

Another option is to use a browser extension that redirects Google Voice links to the app. There are several extensions available that can do this, such as "GVoice Redirect" for Chrome or "Google Voice Redirect" for Firefox. Once you've installed one of these extensions, it should redirect Google Voice links to the app whenever you click on them in Outlook.

Thank you for the reply. This did not work but there also seems to be some steps missing based on the link i included (assuming that kb should work).

Thanks again for the input.

Hello there,

Maybe try blocking link and redirect it to open the Google voice app.

Learn how to launch the default app for a Uniform Resource Identifier (URI). URIs allow you to launch another app to perform a specific task. This topic also provides an overview of the many URI schemes built into Windows.
