On Thursday the company credited users for changing its mind. "None of this would have been possible without the great feedback from you, our users," said the Hotmail team.

Other changes will be coming, said Microsoft, including moving ads to the side of the window and increasing the number of messages shown at one time. The latter was a modification that numerous users griped about last month.

Users can revert to Hotmail's earlier scrolling behavior by clicking the "Inbox" folder, clicking "Options" in the upper right, then under "Reading pane settings," selecting "Off."

Since Microsoft told users of the scrolling change, more than 100 users have left comments about the move. But while some applauded the concession, many more continued to urge the company to completely turn back the clock. "I want Hotmail back like it was!" said a user identified as in a comment early Friday. "I am not happy."
