The disk is already dynamic and spanned. looking at your picture you can't extend E: since the logical partition that contains logical disks is to the immediate right which means if you reduce the size of ANY of the logical disks (the one at the far right) and then shrink the logical partition the contiguous space will be to the extreme right and not immediately after drive E:

I would do; stop the Exchange if possible, have a disk backup and then execute the extension.
