Outlook 2007 Appcrash in Windows 7

First make sure all your Office patches are up-to-date. There are a lot of them if you just installed Outlook on a new machine. Then, use Office Diagnostics to see if it can do a repair. My initial guess patches and office service packs. ... Thinkpads_User

Does it crash if you start it in safe mode ?

Open Outlook via Start, Run, "outlook /safe". If it opens, go into
Tools, Trust Center, Add-Ins, and disable all add-ins.
Then try opening it normally.

C&P from another forum which more or less covers it all :

Outlook 2007, the latest version of Microsoft Office Outlook, is generally considered as the reliable and safer
version as compared to its former counterparts. But, Outlook users still observe frustrating experiences with Outlook 2007. Outlook 2007 might crash randomly while you are performing general tasks like sending or receiving emails, starting or existing Outlook and others. One of the typical causes for Outlook to behave in this manner is PST file corruption, which leaves you with no other option than to restore from backup or use PST Recovery tool (if backup is invalid or absent).


There can be a wide variety of reasons causing Outlook 2007 to crash. Some of them are listed below:

*

Outdated Outlook installation
*

Add-ins or extensions issues
*

Problematic Outlook profile
*

Corrupted Outlook installation
*

Damaged Outlook data file (PST)
*

Damaged Windows profile
*

System specific problems

Solution

To fix Outlook 2007 crashing issues, you should consider these methods:

*

You need to ensure if the crash occurs when you perform a particular task, for example while opening a particular email message or meeting on calendar. If this is the case, you can perform steps like deleting the specific item or doing a similar task as per the cause.
*

You can try updating Outlook installation with the latest cumulative updates available
*

Microsoft Outlook provides different command-line switches that allow you to start Outlook after cleaning few application settings. Based on the specific problem in existence, you can use these switches to troubleshoot. For example, if crash occurs when reminders are fired, you can use /cleanreminders switch to clean and regenerate them. Whereas, if issue is related to invalid profile keys, you can use /cleanprofile switch.
*

Outlook installation might be damaged. So, you can try reinstalling Microsoft Outlook 2007.
*

Starting Outlook using /safe mode allows you to start it without loading many of the customizations, Exchange Client Extensions, reading pane, customized toolbars, and COM add-ins, Form regions, macros etc. So, you can use it to start Outlook. If you find that Outlook doesnt crash when you start it in /safe mode, you need to check the list of disabled items to see if any of them relate to the type of kind of crash you suffer. If this is the case, you can disable, remove or rename the item, as per the case.
*

To check if the issue is Outlook profile specific, you can create a test profile containing no email accounts. Since it doesnt have any email account, it will not send and receive any email messages. You can try adding the existing PST file to see if PST is not damaged. It will create a PIM profile. If it doesnt crashes, you should continue working with this new profile.
*

You can try to test the new Outlook profile with your email accounts as all the times, Outlook profile might not be the issue.
*

If Outlook crashes after adding PST, the file might be damaged. Thus, you need to repair it using Inbox Repair Tool or alternatively by using commercial PST Repair tools.
*

If Outlook crashes after trying a new profile, you should try creating and using a new Windows profile. If problem gets solved, you should keep continuing work with this new profile and delete the earlier one.
*

If testing through new Windows profile doesnt help, the issue could be machine-related. It could occur due to problems like faulty RAM, damaged files, wrong data in HKEY_Local_Machine hive, incompatible software or faulty Windows. So to check this behavior, you can perform steps like using Outlook on a different system, checking Office installation, performing Windows clean boot, replacing the corrupted RAM and other similar steps.

I see that you're using the Service Pack 2. So I would first try to update the system from Microsoft update.

Secondly, I would try to disable the antivirus software which can also cause this behavior. BTW, which one are you using?

0xc0000005 is typically a faulty RAM or a bad device driver, although it don't necessary have to be, but you can download Memtest86, burn it to CD, boot from it and test your RAM.

however .... you said 'transferred' ...
Does that mean you just copied and pasted your outlook.pst
from there to your new installation (
If so,... bad mistake.....
Save your mails - rename your current *.pst file to something else (*.pstold)
and place it in some other folder than C:\Users\*****\AppData\Local\Microsoft\Outlook
and restart.Outlook will recreate the fileIf all work well,rename file back and import its contents from Outlook
using import wizzard...

Senad, thanks for the overwhelming reponses! I didn;t just copy and paste my PST, I exported and imported the elements I needed to transfer. My Outlook and Windows 7 is fully up to date, all patches applied. I think the add-ins are the problem. I did not want to install the Business Contact manager add-in but was nagged to death by Outlook so eventually I thought I'd let it install, I could always remove it. Now Outlook start in Safe mode, but when I try to remove all add-ins, it won't let me - says I need to be an administrator - I am the ONLY administrator for this machine!

However, I can now open Outlook and work with it, so if that continues to be the case I'll give the points to your 3rd response. Many thanks,

ADC

You should make a shortcut to Outlook with the /safe switch, then right click it and 'Run as administrator', see if that helps.

Or you could start an elevated command prompt and run 'outlook /safe' there.

Thanks, Beester. That allowed me to disable all the add-ins, but to no avail - Outlook still crashes after launch with the same error message. Help!

I notice one slight change - instead of saying "unknown" for Fault Module Name, now it is saying "wwlib.dll" - does that give anyone a clue?

Hi. Make sure Outlook is closed, then search for the file wwlib.dll - rename it to wwlib.old, start Outlook with the /safe switch, go to Help - Office Diagnostics, and run the Diagnostics. Maybe that will help.

PS! You might need your installation media for this.

Thanks Besster. Tried what you said but it just reinstalled th DLL and crashed again afterwards. So I tried senad's new profile, and hey presto! it worked. So the old PST file was corrupt and senad gets the points. Many thanks.
