In an older version of Outlook, the current day's background was darker. Now there is just a small blue line. I spend to much time looking for the current day and the monthly view.
I have to print to pdf an email wish I want to refer back to and put it into an outside file. Not found an easy way of saving a conversation, other then creating sub directories under the inbox. It is inefficient and too much work to keep up. The searches rarely work well.
One used to be able to attach an appointment to a contact. For some reason you took it out. It was very valuable, to me at least.
