If you're running macOS version 10.10 or later (Yosemite or later), you can use the Mail, Calendar, and Contacts apps to connect to your SISSA account. These instructions use macOS 11 (BigSur), result may be vary on different versions.

Configuration

Follow these steps to set up a SISSA email account:

Office 365 accounts are backed up for 30 days. Outlook on the web and some desktop versions of Outlook let you recover deleted items that are no longer visible in the Deleted Items folder. In Apple Mail you can set how long to keep messages in the Trash folder.

    • Store deleted messages on server: checked
    • Erase deleted messages: Never
