This can be done via Task Scheduler on the Proclaim Server.
However, it is best to ask your IT support to make these changes as they may be backing up the databases at that time or other user information that be affected if a user is logged onto the system and Proclaim.
If you need help on this issue from us then please ask a question in the MyAccess Portal Digital Assistant and ask to "Speak to a human" to be put through directly to our support team.
