In Windows 10 Pro, I am finding when I use the GoToMeeting Windows Store App (NOT the desktop application), when attempting to invite an attendee, Windows prompts for an application to 'share' with. It seems to only detect Mail and OneNote.
It should detect my default mail client, that being Outlook 2016, x86.
The version of Outlook does not come from Click-to-Run and was installed via MSI in Office 365 portal. It's the 32bit version, and all other applications recognize it as the default mail client in the OS.
I tried a few steps to resolve this, including repairing Office, re-installing Office, and from a completely different machine, but the same behavior occurs. It seems to me the Windows Store app cannot probably detect native desktop applications.
