Hi Stuart,
There are several factors that can cause the problem you are experiencing, such as:
1. Conflicts between Outlook and Anti-virus programs such as Norton or MacAfee.
2. A corrupt Outlook profile.
3. Corrupt Outlook program files.
Narrow down this issue by troubleshooting the following steps:
Step 1: Temporarily disable any anti-virus/firewall software.
===========================================
Temporarily disable Norton and any other anti-virus/firewall applications to see if the problem is related to anti-virus/firewall software. If the issue persists, perform step 2.
Step 2: Start Outlook in Safe Mode
===========================
Safe Mode will disable all add-ins and extensions that will start, as well as any corrupted resources, files, registries and templates.
(a) Close Outlook.
(b) Click Start menu-> Run, type "Outlook /Safe" (Quotation marks are not included and there is a space between Outlook and/Safe) and press Enter.
If the problem goes away in safe mode, there is an Add-in that is causing a problem.
Step 3: Create a new profile to see whether the issue persists.
==============================================
Create a new profile to test if the problem is related to a corrupt profile. Creating new profile will not do any damage to the old profile.
Please refer to the following KB article for information on how to create a new Outlook Profile.
