I am trying to convert very large .dgn file sizes to a smaller pdf size to make uploading easier on my company's website. I have be able to reduce it a significant amount by changing the dpi, but I am not very familiar with MicroStation, so I am looking for some help. Does anyone know of a way to reduce the file size? I have been using Adobe and Bluebeam to do this.

MicroStation files contain 3D models. They store data, such as 3D coordinates, in 64-bit precision floating point numbers. DGN is a very different format to PDF, which uses a different representation for 3D geometry. It's not clear what you mean by 'convert very large .dgn file sizes to a smaller pdf size'.
You can print from a MicroStation to a PDF? Have you tried that?

Use some combination of the following settings to reduce the pdf file size. Change the driver resolution (sounds like you already tried this). If your plots are rasterized, there is a setting in this group called Rasterized Quality Factor. Lowering this can also reduce the file size. Also, under the Base Properties tab, pick Raster Printing, and lower the quality factor. You can try different values to find out what setting reduces the file size and still get acceptable quality. You also may try setting Enable Optional Content to Off (this turns off creation of levels in the pdf).
As to raster change resolution, I suggest you try to do this at print time at first through the printer dialog box settings when your doing testing rather than edit the driver settings as its easier to understand ( if your unfamiliar with mnst) and you can just keep tweaking by the slider bar or value typed and it doesnt change the driver then when youve found the optimum setting you can visit the driver and make the change once..
