I have a static map image using the standard google maps url without an api key.
This seems to work for every email client, except recently for outlook.live.com.
Example
Instead of the expected image, I get a gray jpg with the inscription "g.co/staticmaperror/key", which leads to this documentation .
I know that Google limits the use to 25,000 per day for keyless requests. Is it just that Google recognizes the query limit for outlook.live.com? If so, why haven’t I seen this behavior on other clients such as Yahoo mail? Or how do they measure things like me by opening email in their Outlook desktop inbox?
