I've been saying for years that the Outlook team should all be fire and Outlook permanently retired. M$ should start from scratch using no one that was involved with Outlook as a product. Knowing M$ they'd just buy an email client and calendaring client and go from there. There's no way it could be any worse that Outlook. The only reason anyone uses Outlook is because it is part of the M$ Office Gordian Knot. I wish my employer would dump it for almost anything else.
Some of the problems:
o Cannot get a new member of a team to have access to the team's calendar
o Some events cannot be deleted, even by the owner
o Some events can be deleted by someone who is not the owner
o Some events show up multiple times as if they are different events. I've seen up to 5 copies of the same meeting!
o By default forces you to use formatted text when writing an email
o Hides email addresses so you don't really know who you are emailing unless you poke around.
o Hard to view message source
o Combines calendar and email functions into one app. making it harder to see both at the same time.
o Maybe it has an alarm function, but I haven't seen it for events. All you get is a notification which can be easy to miss, especially if you have multiple monitors
Please just make it go away!
