Pasting to Outlook or Windows Mail
Outlook, Outlook Express and Windows Mail require a different clipboard format to other graphics programs.
To paste graphics directly into emails, check this item in Tools / Options.
Note:
This option also has an effect on how graphics are pasted into MS Word. With
the option unchecked, you can paste large graphics into Word and Word will automatically
re-size them to fit the page margins. With this option checked, Word will always
paste in graphics at full size and crop them to fit the page margins.
