Configuring the 'Mailto' Protocol for Gmail in Chrome

These instructions have been tested with the Chrome browser version below.
07-19-2023 Chrome Version 115.0.5790.99 (Official Build) (64-bit)
"Mailto" is a Uniform Resource Identifier (URI) scheme for email addresses, which is used to produce hyperlinks on websites that allow users to send an email to a specific address directly from an HTML document. If you are using Gmail, mailto commands will not work by default and you must configure "mailto" for use with Gmail. OA Mobile, like any other application or webpage, uses the "mailto" URI to send email to your preferred email client. If you do not have the "mailto" command configured to use your preferred email client, OA Mobile (nor any other application or webpage) will be able to send email to your preferred email client. Please follow steps A - D below to complete the configuration.

When you configure Google Gmail to use the "Mailto" URI, you are telling applications to send URI links to your Google Gmail account. Before Proceeding, log out of any open gmail accounts you are currently in, and close the Google Chrome browser (this means shut it down, not just minimize it). You can only send email to one active gmail account at a time via the "Mailto" URI. This means that if you are logged into multiple google and/or gmail accounts, the "mailto" URI will not work and/or will be unpredictable.
