Since last upgrade my Outlook won't open but all other Microsoft Office programs will. I have rebuilt my identity several times. I can't access any of my email but I can hear it dinging in the background like I'm receiving but can't get to it. Pls help!!!

Need a bit more info. Did you update your OS or did you update Outlook? Which versions of both are your running? (I'm assuming you're on Lion 10.7.5). Is that the only update you made before Outlook stopped working?

If you can hear the e-mail notification that means that Outlook is running (or in your words "open"). So perhaps it is that you do not see the window with your e-mail messages listed. Yes?

To verify that Outlook is running/open, hold down the command key and press the tab key. You should see icons of the open applications pop up. Press the tab key again and it will move to each application. When the Outlook icon is highlighted, release the keys.

Do you see the Outlook menu row at the top of your screen? If yes, then on the menu row, click File, then New and from the sub pop out menu, select Open New Main Window.

You might alway want to check out the Microsoft site and see if there are any updates for Outlook / Office that you can download. Wouldn't be a problem if you went from 10.7.4 to 10.7.5, but could be an issue if you were not previously on Lion.

Ok I did that and there is no icon for Outlook so I'm assuming now it's not open?

The fact that you were here the email notifications is still curious. Another way to check if an app is open is to click on the Apple icon menu and select Force Quit... In the Force Quit Applications window, is Outlook listed there?

It seems like it updated my excel/word but Outlook still won't load. It opens then immediately closes.

At least you actually saw Outlook launch and quit. Since your original post stated that the problem started after updating the OS, try launching Disk Utility (in the Utilities folder) to verify that your hard disk is okay. If it reports OK, then Repair Disk Permissions. Reboot the computer.

If the problem persists and you updated the OS using Software Update, you might try downloading the OS 10.7.5 combo update and apply the update again.
