Salesforce for Outlook - What IP addresses does SFO need to connect?
|Knowledge Article Number||000232276|
|Description||Salesforce for Outlook (SFO) needs to have access to our servers on port 443 to make a successful connection. Sometimes due to organizations security policy or network configuration not all IP address for outbound traffic are white listed and their IT team must manually white list the IP addresses used by SFO to allow the connection
SFO tries to connect to a range of IP addresses depending on the customer's instance. To find out white IP addresses must be white listed by your IT or networking team you can ask them to do a NSLOOKUP on the following URLs and grab the IP addresses and then white list them in the firewall or proxy settings.
1- First URL would be associated to your org instance.
To find out what instance your org is on, simply login to Salesforce.com via a browser and after you login, check the browser address bar to see the instance that starts with NA* right before the .salesforce.com
For example in the following screen shot, the org is on NA5
2- Second URL would be the login.Salesforce.com
3- Third URL would be your MY DOMAIN URL. If you do not have My Domain enabled you can ignore this.
Now that we have all the URLs we need, we run the Command Prompt and using the NSLOOKUP utility obtain the associated IP addresses.
Here is an example of the NSLOOKUP commands using the set q=a query
Text in bold below are commands that need to be typed by the user.
You can type in your My Domain URL as a command to obtain the additional IP addresses
