As Outlook users, please note that Exchange 2016 requires at least Outlook 2010 with KB2965295, Outlook Mac 2011, or newer clients. Older versions of Outlook can only be operated as IMAP clients.

You should also use the latest versions of IE, Chrome, Firefox or Safari browsers. For IMAP clients such as Thunderbird, Evolution, and other no significant changes are expected.

When you type in the browser, you will get the new OWA (Outlook on the web) of Exchange 2016. Login will be possible as usual by entering your access credentials.

The migration of mailboxes will be done in batches. You will get an email notification, when the migration of your mailbox is started.
