Microsoft 365 Email Service

The SISSA e-mail service is unified under the domain

Every user has at least two email addresses activated:

  • Primary SISSA email address:
  • Secondary email alias:

Both are associated with the SAME MAILBOX, accessible as usual with the personal account credentials.

The maximum message size is 25MB (but it can grow up until 150MB, if needed).

If your mail contains graphics or generally files, not in text format, the mail server can increase your message size, so we suggest to limit the size of attachment to be smaller than 25MB.

The webmail service (Outlook on the web) is a web-based email client that requires at least Microsoft Edge, Internet Explorer 11, Mozilla Firefox, Apple Safari 10+ or Google Chrome to work.
