Did your connection status bar disappear? The one that tells you how many Items you have, and whether or not you are connected to exchange or any other service?
Quick fix to make it show again!
If you don’t have the ribbon enabled, you will go to View and make sure “Status Bar” is checked. Voila! It’s back!
If you do have the ribbon enabled, you can only adjust what you can see, so just Right Click and your options for what you can see will come up!
