When starting Microsoft Outlook, a significant delay is experienced, resulting in a "Could not access network location \Hewlett-Packard\\" error.




A number of possible causes would need to be investigated, as this error could indicate a conflict with a third party application. This error can be caused by an entry in the registry which causes issues on Windows 7 when running some installers.


  1. Monitor Mimecast for Outlook performance by:
    1. Ensuring the latest Office Service Packs are installed
    2. Uninstalling Mimecast for Outlook and record the Microsoft Outlook load time.
    3. Perform a clean install of Mimecast for Outlook, start Microsoft Outlook, and record the load time.
    4. Disable the certificate check for publisher’s revocation and server revocation (in Internet Explorer).
    5. Start Microsoft Outlook and record the load time.
    6. Temporarily disable all other add-ins apart from Mimecast for Outlook.
    7. Start Microsoft Outlook and record the load time.
    8. Submit the findings to Mimecast Support, along with your Mimecast for Outlook Logs, for further analysis.
