The College ICT team are still able to provide support as usual for your ICT problems and questions. If you need help, please contact them through the usual methods, either by email to it-support@lmh.ox.ac.uk or by phoning 01865 619111. The team has access to a remote support tool that will allow you to share your computer or smartphone screen with us so they can help you, even at a distance.
Many of the University IT systems are available remotely, although some will require you to use the VPN system, full details are on this page: https://www.it.ox.ac.uk/work-remotely
