I saw a similar thread that was archived, but in version 91.5 I have experienced the following issue: I receive a message with about a dozen large inline photos, so the message totaled about 10 MB. I used the View->Message Body As->Plain Text setting to allow the images to show up as attachments. I then selected all of them and detached them. They were saved to the selected location on my hard drive. But the email is still 3.1 MB in size, even though there are no images. I then went back to the message and viewed the attachments list. They were changed to blue links, as expected, due to the detachment. I tried to right click and delete each one, but only one would let me actually delete it (shows the filename as "deleted image.jpg" now). I tried deleting the detached images from my hard drive and now the links are in strikethrough font, which makes sense since the links are broken (I don't need the images anyway). But the message storage size remains at 3.1 MB and I can't seem to shrink it. Viewing the raw source of the message I can see a large section of base64 encoded text that starts as follows: --_020_BY5PR01MB57149BC30688560D986EB5B4E35B9BY5PR01MB5714prod_ Content-Type: image/png; name="image003.png" Content-Description: image003.png Content-Disposition: inline; filename="image003.png"; size=2265087; So it appears the large section of text is actually 2+ MB of image data for an image called "image003.png". But viewing as plain text doesn't seem to allow me to delete that image. In fact, "image003.png" is not listed as one of the attached images at the bottom of the window. There are still 10 or so other images (deleted/broken link) listed there, but not this one. Is there a way to reduce this message's storage size and get rid of that encoded image data? Thanks!
