In the PowerPoint Add-in, configure the settings file for the add-in to enable connections via a proxy server.
You should have an intermediate to advanced knowledge of XML to adjust the settings file. If you're not familiar with XML, ask your Tenant Administrator to configure your proxy settings.
When you install the add-in, a settings file is created in the following location:
To make changes to the proxy settings, open this file in a text editor, for example Notepad.
For proxy setting changes to take effect, ensure the DefaultProxy setting is set to true:
When you install the add-in, there's no section in the settings file for proxy settings. Previous versions had a section for proxy settings by default.
To adjust the proxy settings in the settings file, use the text in the image below as a template. Insert the ProxySettings tags after the Features tags and before the close of ApplicationSettings tags.
If you've added this text to the default settings file for the add-in, your file displays as below:
Once you've added the text above to your settings file, you can replace the value between the SelectedProxy tags to select different proxy behaviors. The valid values for proxy settings are:
- None: Use if you do not need to use a proxy. This is the default behavior if proxy settings have not been configured in the settings file.
- Legacy: Use to enable the add-in to support your system's proxy server. This setting attempts to connect you to your system's default URL for proxy servers. To change this URL, see Microsoft WebProxy.GetDefaultProxy Method . The add-in reads Microsoft Internet Explorer (IE) proxy settings.
- System: Use this as an alternative to the Legacy setting, to enable the add-in to support your system's proxy server. This setting attempts to connect you to the non-default URL defined for proxy servers in your system. To change this URL, see Microsoft WebProxy.GetProxy(Uri) Method . The add-in reads Microsoft Internet Explorer (IE) proxy settings.
- Override: Use to enable the add-in to support a proxy server of your choice. This setting bypasses your system's proxy server and uses details you provide in the settings file.
To use this setting, you must provide additional values for the SelectedOverrideProxyName and OverrideProxies tags. An example can be seen in the prior section on this page. Within OverrideProxies you must define one or more proxies. To define a proxy, you must provide a:
- ProxySetting Name: This must be logical but can be whatever you want it to be.
- Address: This must be the HTTP address of the proxy server.
- Port: This must be the port for the proxy server.
