Anyone knows why email images in Microsoft Outlook are so big sometimes? The same email looks fine on ThunderBird.

Yeah, we had a lot of trouble with it. I had to add some comments to the email to make it work. You can find info here: https://stackoverflow.design/email/base/mso/. I guess Outlook doesn't read the CSS the same as other email platforms so you have to put in their own.

That is too bad, they spent a lot of time on the design (it is way better than thunderbird), but not on rendering. But I was talking about the ones I receive. Not what I am sending.
