One Month Until Faculty and Staff Email Migrates to the Cloud

January 17, 2023

Dear GC Faculty and Staff:

On February 9, 2023, the Graduate Center will migrate faculty and staff email to CUNY's M365 cloud.

What to Do Now:

  • Search and remove email messages or attachments 35MB or over from your mailbox or any shared mailboxes.
  • Delete any emails you do not need to maintain.
    • Note: The number of mail items in your mailbox may impact how quickly IT is able to copy your email data to the cloud. It may also impact your Outlook performance once we transition to the cloud.
  • Empty your Junk and Deleted Items email folders.
  • Unsubscribe to any RSS Feeds to which you currently subscribe and delete any mail items related to the RSS feeds that you do not need to retain.
    • ​It has been strongly recommended by other campuses who have migrated to the cloud that users unsubscribe to RSS feeds because they may cause the user's email migration to fail.

​What to Expect Before Migration:  

  • GC IT will begin copying the context of inboxes to the cloud approximately one to two weeks before our migration date​.
    • ​Users may experience intermittent Outlook slowness during this time.
  • You will receive an email explaining the steps you should take the week of the migration.

What Items Will Not Migrate:

  • Any rules you manually created in Outlook
  • Any personal contacts or contact groups you created in Outlook Contacts
  • Any mailbox delegations you created for your mailbox
  • Any email messages or attachments that are 35MB or larger in size

​What Changes to Expect in the M365 Cloud Mailbox:

  • Shared (Non-Human) mailboxes will have a GC prefix in the Outlook address book (Example – GC Information Technology).
    • The email address will not change, only the descriptive name used for lookups.
  • The Microsoft Windows Report button replaces the Report Phish button, enabling you to report spam and phishing.

  • There is a single mailbox in M365 that will house multiple campus email addresses.
  • You will not be able to send or receive emails or attachments bigger than 35MB. If you need to share files larger than 35MB, IT recommends placing them on OneDrive or Dropbox and emailing a link to the file.
  • Microsoft has ended support for basic authentication methods such as POP and IMAP. Microsoft will only support email apps that use modern authentication. For a list of unsupported apps, read “What to do once POP and IMAP Basic Authentication is no longer supported?".
