I have third-party plugins installed with Outlook. Could they be causing problems with Outlook Connector?


Question:

I have third-party plugins installed with Outlook. Could they be causing problems with Outlook Connector?

Answer:

Some third-party Outlook based plugins may not work correctly with Outlook Connector as they are designed to be used with PST (typically POP3) accounts and Outlook Connector does not use a PST.

Typical problems this can cause are emails with no body or attachment, or emails which appear to have switched their message body with another email as the plugin is interferring with Outlook Connector committing data to it's localcache.db file.

Outlook based plugins are located in Outlook in the following locations:

Outlook 2000/2002/2003 - Tools -> Options -> Other -> Advanced Options -> "Add-in Manager" or "Com Add-ins"

Outlook 2007 - Tools -> Trust Center -> Add-ins -> Manage: "Com Add-ins" or "Manage: Exchange Client Extensions"

Outlook 2010 - File -> Options -> Add-ins -> Manage: "Com Add-ins"

We would recommend disabling all add-ins and extensions except Outlook Connector.

If, when unticking an add-in you get the following error message:-

"The connected state of Office add-ins registered in HKEY_LOCAL_MACHINE cannot be changed"

...you'll need to disable the add-in from the registry directly. To do that, close Outlook and then use the Registry Editor to navigate to:-

\\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins

...locate the add-ins in question and change the value of the LoadBehavior key from 3 to 0 for each add-in before restarting Outlook. As always if you're unsure about editing the registry, take extreme care and back-up where necessary before making changes.

We also strongly recommended that any AntiVirus or real-time scanner product in the above locations should not be enabled or scanning the Outlook Connector localcache.db file (see http://www.zensoftware.co.uk/kb/article.aspx?id=10130)
