"Office 365" refers to subscription plans that include access to Office applications plus other productivity services that are enabled over the Internet (cloud services). By default, all UW-Madison Office 365 users have access to email, calendar, and people. You can use many different clients to connect (via an email protocol) to your Office 365 account.
A client is an application that is used to connect to your Office 365 account. Some examples include Microsoft Outlook or Internet Explorer/Google Chrome.
Email protocol is a method by which a communication channel is established between two computers and email (some protocols also include calendar data) is transferred between them. When an email is transferred, a mail server and two computers are involved. One computer sends the mail and the other one receives it. The mail server stores the mail and lets the receiving device access it and download it if needed.
Even though Microsoft provides you with the ability to connect to your Office 365 account using a wide variety of clients/protocols, for the best experience and complete support, Microsoft recommends connecting through one of the following ways:
Abuse of the email service by compromised NetID credentials is a very large and growing issue at UW-Madison. These credentials are used to access mailboxes, send out phishing to other people, and potentially exfiltrate sensitive email messages.
SMTP Auth is deprecated and is no longer supported. The Wisc Account Administration site will only show the status of this protocol for an account.
Individuals who had SMTP Auth enabled for their account before January 2019 can continue to use this protocol. If the protocol is disabled, it cannot be re-enabled.
Microsoft has not stated that IMAP and POP functionality will end, so the UW-Madison Office 365 team believes that IMAP and POP will continue to function after 2020. However, based on conversations with our Microsoft partners, it is clear that they are advocating strongly for the deprecation of clients and protocols that aren’t capable of using Modern Authentication.
Modern Authentication is what enables enhanced security, in terms of password handling and Multi-Factor Authentication. Microsoft’s position, coupled with UW-Madison’s needs for enhanced security of credentials and authentication flows, means that the UW-Madison Office 365 team is taking the strategic position of encouraging people to use clients capable of Modern Authentication by default.
Yes. Some people configure Gmail (or other 3rd party services) to POP email out of their UW-Madison mailbox. This requires Gmail store the password in a decryptable format on their servers.
Technically, this is a violation of UW password policy, however we recognize that many people have been doing this for years, so that is why there are no plans to disable POP for existing accounts.
Important: Make sure you have reviewed the "Under what other circumstances would these protocols be disabled for an existing account" section above before proceeding to make changes to any of the protocols.
If you would like to enable/disable the POP protocol, use the following steps:
Note: If a protocol is disabled, the account cannot be used to connect to Office 365 via that protocol. It may take up to 24 hours for the change to be reflected within Office 365 infrastructure.
If POP protocol is disabled for an account, any client that attempts to connect via POP protocol to your Office 365 account will be unable to connect (some type of connection error). Below is a list of errors you may receive:
