I bought an expensive microphone just for work, and then people complained that it was taking up all their bandwidth, they asked me to go back to using the phone.
No simple answers.

You should not believe everything people complain about.
Also, you don't need expensive microphone. You need decent one set up correctly.
Most microphones are actually pretty decent in that they can record your voice pretty well provided they are set up properly and that is where usually problems are. You need to have correct geometry so that they can do their job of picking your voice and rejecting noise and you need to ensure correct software audio settings because mismanaging these can cause voice to be distorted or sprinkled with clicks and cracks.
Actually a microphone with good noise rejection may help depending on how exactly the audio is being compressed. Less noise will usually cause either less bandwidth used for the same quality or better quality for the same bandwidth.
Then how did they know?
I'll try it out on Monday.
It might be causing some other kind of issues but a microphone can't really "take up someone's bandwidth"... That's not really how things work.
I'd have filed the information and then verified the bandwidth claims. The claim sounds highly unlikely.
I haven't heard anyone complain. Rather, everyone else also bought expensive microphones and enabled original audio, and the results are excellent.
(Unsolicited tip: some sort of noise gate is really nice so that when you unmute, it doesn't raise the noise floor for the call. I ended up using Krisp, which seems to work quite well. Yeah, it's a subscription service for something your audio interface could theoretically do, and they market it as AI but it's not really AI and that's kind of scummy, but it doesn't take up any space on my desk, and it's not that expensive, so whatever. Sometimes it works too well -- people will apologize for their dog barking, or a fire truck driving by, and it's just met with confusion because that all got filtered out.)
I didn't tell them, "I'm about to switch to the microphone", I switched to the microphone and they told me to stop and they claimed it was using all their bandwidth and to go back to using the phone instead of the microphone.
I'll take the downvotes, that's fine, but how did the people complaining know I had switched to the microphone and what were they complaining about?
That's not how I expect your choice of mic to affect anyone else's experience.
It would surprise me if additional network load is part of what happens.
