Outlook has started to throw up errors

I am using Outlook 2007 client to access NHS mail. It has worked perfectly fine so far, but since today morning its throwing error.

Unhandled exception at 0x53F03620 (OLMAPI32.DLL) in OUTLOOK.EXE: 0xC0000005: Access violation reading location 0x00000010.

I have ran repair option and uninstalled and re-installed the client but still the same problem.
Also when I had the opportunity - ran the debug - when it was offered

The system also uses an enterprise version of GroupWise. Both have coexisted quite happily.
Apart from this error, there is nothing much else I can see.

1 - try running outlook in Safe mode  - if the error stops - go through the add-ins - one of them will most likely be the problem

2 - Do a memtest  on the ram - from a bootable CD

3 - Check the person's hard drive for errors  (Chkdsk /f)  

4 - Clean out your Temp folder

5 - Check for Malware - I usually run a stand alone Malwarebytes regardless of what Virus software is running (Last week I had a client show no errors running an up to date Norton  yet MalwareBytes ran   and showed over 250 problems including a keyboard logger

Would be worth adding to the solution to run a Registry checker and application remover to do a clean up.

OK my posted comment was not saved.
in addition to the suggestions made - I uninstalled the application (again), ran a registry checker / application remover / then ran chkdisk /f.
Can only presume that there must have been some corrupt data left over the first time round.
Thanks again.
