Of course not. You need direct heat to make toast and microwave ovens don't cook that way. The microwaves only jiggle the water in the food and make it hot. All you will get is hot bread. Same reason you can't roast anything in a microwave - put a chicken in and it will cook, but it won't get brown.
I remember when microwaves first came out and people tried to cook everything in this whizzy new gadget. It doesn't work! If you just want to make food hot, it's great. It does that quickly and efficiently. But it cannot initiate the Maillard reaction - that's what happens when you apply actual heat and the food goes crisp and brown. Which is why some microwaves are combination ovens - they have a grill element in the top and if you switch that on at the same time, THEN you can have food that is hot AND brown!
Do what chefs do - fry it in a pan with a little butter, and that will do the trick to make it crisp and brown. Or do you have a grill (broiler)? That will make toast - it's what we always did at home before we had a toaster. Of course with either method you will need to keep an eye on it so it doesn't burn, and turn it over to toast the other side.
Or is your microwave a combination oven? Then you can make toast in it. I used to have one. If you have one, it should come with a rack that enables you to put bread in so it's close to the top, set it to grill only, and if I put bread in for 2 minutes one side, turn it over, grill for 1 minute more, that made great toast. It's the only thing I ever used the grill setting for!
