Impact: connection interrupts for exchange mailboxes

In our maintenace window on thursday between 5 p.m. and 7 p.m. some connection innterupts to the Exchange mailboxes will occur. This is caused by important changes to the system regarding the migration of the students mailboxes. This already caused some problems with the Outlook client through the weekend.
