When using the SILQ Outlook add-in on a Mac, we recommend disabling IPv6 as in some instances it doesn't allow SILQ to recognise that you are logging in from the same device.
To turn off IPv6 in your Mac settings:
1. Open System Settings from Launchpad, go to Network, and click the Details… button next to your network.
2. Go to the TCP/IP tab → Configure IPv6 and select Link-Local Only from the dropdown menu.
You may need to restart your computer before any changes are applied.
How to verify that you’ve turned off IPv6
Visit ip.me (without a VPN connection). If you see a short IPv4 address that looks something like 185.159.159.142, then IPv6 is disabled. If you see a long hexadecimal number that looks something like 2001:db8::8a2e:370:7334, you’re still connecting over IPv6.
