Bugs, Bugs, Bugs and Horrible Performance. A new low for Microsoft!
Excel pivot tables have bugs, can't sort dates in normal MM/DD/YYYY format.
Outlook has bugs, can't recover recently deleted files. Deleted drafts can't be recovered. Autosave interferes with typing. Can't sort by keyword in archives. Takes forever to do basic tasks. Really dislike the default sorting into focused and other and junk - ineffective does not allow the user to determine what works for them. Basic issues that should have been caught in UAT and beta testing were not. Simply disgraceful. It's not a productivity tool - it takes much longer to get things right and wastes users time. Sad.
