I have some add-ins that load on start up. I can't disable this from happening as I don't have administrator rights.
I am writing a program that opens outlook and sends emails, but it is slowed down by these add ins. Is there a way to programmatically disable add-ins after opening outlook using python (e.g. using the win32com package)? 
I need to do the same thing for Excel too. Any advice would be appreciated.
You can disable the addins by setting the LoadBehavior value appropriately for the problematic addins in HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook.
