We will be moving ICTS staff mailboxes from on-premise Exchange 2010/2013 servers to the Office 365 Datacenter (in Europe…), next week. We hope to use this as a final test before we start with the rest of the 9000-odd mailboxes.

A lot of work and preparation went into this project, and after this is done, the only box to be ticked will be to migrate away from Mailman as our mailing list software.
