According to this article (October 8, 2013), Yahoo is reducing the amount of free storage it gives users of its email service from "unlimited" to 1 terabyte:
"We're moving to 1TB because 'unlimited' wasn't a feature that we discussed very much or a feature that our users were that familiar with," a Yahoo spokeswoman explained in a statement to The Times. "We opted to move to 1TB instead, because we believe by having a huge limit like 1TB it will inspire our users to store more in Yahoo Mail."
Does Yahoo Mail truly enforce the 1 TB limit? If so, what happened to users having more than 1 TB?
