We recently installed Microsoft CRM 4.0 using an outsourced model. After installing the Outlook add-in, Outlook performance has slowed considerably, some times making it unusable. We noticed that the client increases RPC calls to the Exchange server by at least a factor of 4, even when Outlook is idle. We're trying to find out if there is a specific function of the client that is causing this that we can disable or if there is anything else, short of removing the add-in, that we can do to fix it.
You can enable the Security on Addins in Outlook so that you get prompted to Load the CrmAddin on Outlook startup. the prompt will delay the loading of the CrmAddin and make the issue disappear.
For OL2007, go to Tools, Trusted Center and check Apply macro security settings to installed add-ins. Restart Outlook.When you now start Outlook, you will get prompted to load the addin Simply Click Enable application add-in and it should work. DONT select Trust all documents because youll not be prompted anymore and this is not what we want.
