My office has boiling water taps that aren't quite boiling. With all things being equal - coffee, grind, equipment - I cannot make a coffee at work with an aeropress that tastes as good as I can at home where I have control over water temperature. Anything I can do with immersion time or grind to improve the coffee when the water is probably in the high 80s rather than 95 degrees or so? No matter what coffee I use it all just kinda tastes the same. At home that is absolutely not the case.
You get less extraction with cooler water so you'll need a finer grind and/or longer steep. Try them one at a time and try both if it doesn't help. The other factor is the water will have been continually heated, which is not as good as using a kettle at home.
