Exchange Online Migration

IMAP/SMTP Setup

OVERVIEW

This article provides the IMAP settings for approved third-party email applications and is intended for individuals who are using the new SFU Mail with Exchange Online experience.

Tip: To ensure the most seamless experience, we recommend that you use more modern ways to connect to SFU Mail, such as using Outlook with Exchange.

SFU Mail Upgrade Implications With IMAP

Before any re-configuring on an email account that has previously been set up with IMAP/POP, we strongly recommend backing up your emails. Any account modifications, such as removing the account, will result in loss of certain messages.

These may vary depending on your application settings, however, the messages can can be potentially lost are:

• Locally saved emails (such as emails within folders set to "This Computer Only")
• Emails/folders not or have yet synced to servers, and
• Any other client-sided customizations, including Email Rules and Flags/Categories.

IT Services has no way to recover any of these messages or settings since they were never stored on our servers.

Prior to the SFU Mail upgrade:

• If you are using Thunderbird, you can re-configure the account settings to connect to the new server when your account is migrated. Avoid removing your account to prevent loss of data.
• If you are using any other application via IMAP, you will need to switch to Thunderbird or use a more modern connection method (e.g., Exchange).
