Provide more details about errors

Description - 

In workspace, when trying to send a report to an email address that doesn't have an Adobe account, if you don't hit "enter" after typing the email, it gives an error and doesn't let you send the file. This can be confusing for users who aren't familiar with the interface. By having more information appear when you hover over the warning icon, it can help users figure out what is going wrong and how to resolve the issue.

Why is this feature important to you - 

This can increase ease of use for users.

How would you like the feature to work - 

When you get an error, provide more information about what is causing the error and how to resolve it (such as hitting "enter" to validate the email address to send the report to) when you hover over the error icon.

Current Behaviour - 

Currently you have to hit enter after typing an email, and if you don't it gives a red warning, but there is no information about the warning/information about how to resolve it.
