Will this work for a microwave exhaust vent?

Depends on the offset and the amount of room that you have above the microwave to make the connection to ducting up through your attic space. I chose the aluminum flex for my application.

Is this 7" diameter ?

This is compatible with most commercial 7 inch ducting. One end is slightly smaller than 7 inches and the other is slightly bigger.

cheaper than cheap
Elbow fell apart before I even got it home. The end section fell off at crimp in the bag. It took me longer to put it back together than to install it, plus I had to tape the seam from coming apart.... crimp not fully made and metal is as thick as a soda can... I have got these before from HD and where never like this.
