Available SMTP, IMAP and POP clients

Software other than Microsoft’s Outlook and Apple’s standard email software will need to be registered by the M365 administrator.

Update 5/19/2023: As with other Microsoft 365 (e.g. Teams), it is now our policy not to register software that requires administrator approval.
Exceptions are Thunderbird and the mail client for people with disabilities. Other registered email clients will be considered for deregistration in the future.

The following software has been registered so far.

• • Thunderbird Version 102.8.0 or later
  • SAITO-KIKAKU Hidemaru-mail Version 7.12 or later
  • RimArts, Inc. Becky! Internet Mail Version 2.81.04 or later
