Upgrade to Microsoft Exchange 2019

The central e-mail service at KIT was converted to Microsoft Exchange 2019. With the renewed software and hardware, the SCC offers all employees and students an up-to-date communication platform with extended storage capacity.

Microsoft Exchange Server 2019

The migration of the central e-mail service at KIT from Microsoft Exchange Server 2013 to Microsoft Exchange Server 2019 was completed at the end of March 2020. By renewing software and hardware components, employees and students now have an up-to-date and expanded communication platform at their disposal.

In addition to the expansion of storage capacities, there were of course also safety-related improvements.

Only TLS 1.2

The TLS 1.1 and TLS 1.0 protocols have long been considered unsafe. Exchange 2019 therefore only supports TLS 1.2.

Older clients that do not meet these requirements can no longer access the system. This concerns for example:

  • Windows 7 computer: Outlook does not use TLS 1.2 by default
  • MacOS computers older than Sierra 10.12: Mac Mail does not support TLS 1.2
  • Android older than 4.2: Mail App does not support TLS 1.2

More storage for the users mailbox

The standard quota of mailboxes has been increased to 2 gigabytes for students and to 8 gigabytes for employees, guests and partners, as well as functional mailboxes.

60,000 mailboxes moved

A total of almost 60,000 mailboxes were moved, which currently occupy an (active) data volume of about 48 terabytes.
