Advice on migrating your own Hermes mailbox to Exchange Online

Students and staff from institutions participating in the University of Cambridge's Microsoft EES agreement can migrate their personal Hermes email accounts to Exchange Online. Here are some factors to consider...

Benefits of Exchange Online for individual users

Migration to Exchange Online delivers the following:

  • 50GB of mailbox storage
  • Send emails up to 100MB in size
  • The ability to share directly from Exchange Online to OneDrive for Business
  • Consolidated personal calendars, making it easier to schedule meetings
  • Group calendars to help teams work together.

Factors to consider before migrating

  • Please consult your College or Institution's support policy and advice before migrating.

  • This option is only for people's personal Hermes accounts, not shared mailboxes.

  • Exchange Online is known to impose certain operational limitations on connections that use the IMAP interface which Microsoft will not address. Consequently, Alpine and unaugmented Thunderbird clients (in particular) should not be used to connect to this service because there is a risk of mail loss when this protocol is used (with these or any mail client).

  • Users who need to be able to securely exchange OpenPGP-protected email should not migrate to the service, as Exchange Online is known sometimes to corrupt such messages.

  • Mailing lists whose recipients resolve to @cam addresses will not need to be changed.

  • Shared mailboxes and migrations from Exchange On Premise must be handled as part of a scheduled institutional migration plan.

  • Migration back to Hermes is technically possible, however it is not being made generally available for self-service users. Requests to reverse the process will be handled on a case-by-case basis by UIS.
