Troubleshoot Outlook problems

Microsoft Outlook is a personal information manager that comes with Microsoft Office and Pocket PC. As a big brother to Outlook Express, it offers you a calendar, a task list, a journal, an address book, and an email manager. I've been using it for a few years now, but even I run into problems that I can't fix.


Last weekend I was having several problems with the program. I blamed the latest round of Internet Explorer and Office patches, inadvertently starting a hoax. I was wrong. Today I'm admitting my mistake and telling you how to resolve your Outlook issues with a couple of free utilities from Microsoft.


Is Outlook eating system resources?


I first noticed Outlook eating up my system resources when my calendar popped up a reminder for an impending appointment. Normally I hit Snooze without thinking. However, my Task Manager was open and I noticed that 100 percent resources had snapped back down to zero. And there it stayed. When I closed the nag, outlook.exe surged to 100 percent CPU usage again. I closed the program and reopened it, waiting for another reminder to rear its head. This time there was no spike up front.


I believe that the shark is tied closely to the calendar. When it flares up, I simply create a new appointment, close it, and all is well. Did you hear that? It was me, breathing a sigh of relief.


The hoax

Unfortunately, here's where I started the hoax. I speculated that the problem was being caused by a hacked DLL. It's not and I'm working with Microsoft and Woody from Woody's Office Watch on a fix.

Compact and Fix Outlook's Information Files

Compact your files


All of the information in Outlook is stored in a .pst file. I find that it's useful to compact this file to save space and speed up Outlook. Here's how:

Right-click the Outlook Today icon and choose Properties.
Click the Advanced button on the General tab.
Click Compact Now to reduce the size of the files in your Personal Folder.

Fix Outlook's information file

If you're having crashes or other weird behavior, Scanpst.exe can help you fix the bugs. This is an inbox repair tool utility that comes with Windows 95, Windows 98, and Office 2000.


Find Scanpst.exe.

Click Start, Find (or Search), and select Files and Folders.
Browse your C: drive for the file named Scanpst.exe.

Launch Scanpst.exe and browse your hard drive for the Outlook .pst file. Here's where it was located on our machine:
C:\WINDOWS\Local Settings\Application Data\Microsoft\Outlook\outlook.pst


Make sure you're logged out of all your email programs and click Start to run the utility.

Here are some other command-line switches for saving Outlook.

Eliminate Outlook AutoComplete Problems

Remove corrupted names from the nickname list


Another bugaboo I can't seem to fix is a ghost entry in my Outlook contacts. Normally this wouldn't be a problem, but it's attached to my name. I email "Chris Pirillo" because I have several accounts for different reasons. When I click on the green-dashed and underlined entry in a recipient field, this is what Outlook tells me:


"The name or distribution list has been deleted and is no longer a valid address book entry."


When I look to remove this dude from my address book, he's not there! Where's he coming from? How can I get rid of him?


If the AutoComplete function is giving you similar fits, try this fix from Microsoft. It'll remove all the nickname entries. Thanks to David Breedlove, a Lockergnome fan, for sending me the link. This is what he wrote:


"Outlook keeps a nickname list that is used by the automatic name checking feature. The nickname list is automatically generated as you use Outlook. If the nickname list is corrupted, Outlook may not be able to identify recipients, or may send the message to the wrong person."


Sure enough, it works! I started with a clean slate and deleted the *.nick file in my home directory. OK, that was easy.
