<p>(a) Parliamentary ICT (PICT) estimates that, following the migration of a user’s mailbox to Microsoft 365, it takes the user’s computer (laptop or PC) an average of five minutes to reconfigure Outlook.</p><p>It can take a user an average of approximately five minutes to reconfigure a mobile device – other than a BlackBerry – that uses ActiveSync to connect to parliamentary email. Following that reconfiguration, it can take up to a maximum of 60 minutes for the device automatically to re-connect to parliamentary email.</p><p>BlackBerry devices need to be physically reconfigured by PICT, and this process can take over an hour – the length of time is linked to the age and model of the device. Furthermore, it takes longer to reconfigure a personal BlackBerry device than a BlackBerry issued by PICT. PICT has issued 92 BlackBerry devices for use by hon. Members and their staff to access parliamentary email.</p><p>(b) It is not possible to provide a figure for the aggregate time taken to reconfigure the above devices because more than one device can be reconfigured at the same time.</p>
