Turn POP and IMAP on and off for users

If you want to sync your personal Gmail with another mail client, such as Microsoft Outlook or Apple Mail, see how to set up POP or IMAP.

If your G Suite users want to use desktop clients, such as Microsoft Outlook and Apple Mail, to access their G Suite mail, you need to enable POP or IMAP access in the Google Admin console. You can enable access for everyone in your organization or only for users in specific organizational units.

Set POP and IMAP options 

Turn POP and IMAP access on and off

Before you turn IMAP off for iOS Mail app users

If you have Apple iOS device users in your organization and you turn IMAP off, let them know that they’re no longer syncing G Suite mail to the iOS Mail app. They might not get a notification on their device. Additionally, new users can’t manually add the Google Account they use for work or school to the device.

To sync G Suite Contacts or Calendar events to Apple iOS apps, you must configure your mobile device management (MDM) service to push that data:

  • If you use Google’s advanced mobile management, enable Google Account in iOS settings. If any Google services required by the iOS apps have restricted app access, you must also explicitly trust iOS apps
  • If you use a different MDM service, contact them for instructions.
  • If you don't use any MDM service, your iOS device users must use Google apps to access their G Suite contacts and calendar events.

Turn POP and IMAP access on and off

  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console Home page, go to Appsand thenG Suiteand thenGmailand thenEnd User Access.

    Tip: To see End User Access, scroll to the bottom of the Gmail page.

  3. In the Organizations section, select the organizational unit you want to configure settings for.
  4. Click POP and IMAP access.
  5. Check or uncheck the Disable POP and IMAP access for all users box.

    If you check the box, POP and IMAP are fully disabled for all users in your organization.

    • Users can't access POP and IMAP settings in the Gmail interface.
    • Users can't access their mail via POP or IMAP even if they originally had it on.
    • iPhone and iPad users must use the Gmail app to access their work or school email. If they try to sign in to an IMAP email client with their work or school account, the sign-in fails silently.

    If you uncheck the box, POP and IMAP using modern security standards is enabled for your users, but IMAP for use with less secure apps remains disabled. To use IMAP with less secure apps, users need to enable IMAP in their Gmail settings under Forwarding and POP/IMAP, and then follow the instructions to Let less secure apps use your account.

  6. Click Save changes.

It can take up to 24 hours for IMAP and POP changes to take effect. As long as the box is unchecked, users can configure POP and IMAP access for any supported mail client.

Username and password not working? 

Some apps require you to also turn on access for less secure apps before setting up POP/IMAP connections.
