I'm using Outlook for Office 365. Ever since the last Windows 10 update, I can no jump to messages in the From column by first sorting the column, and then typing letters on the keyboard. For example, clicking on the From column label (which sorts the column in ascending or descending order), then clicking on an email message, and then typing an "S" should jump directly to the first message from a recipient whose name begin with "S". This functionality is no longer working for the "From" column, although it's working for other columns.
