IMAP/POP Settings

G Suite Sync for Microsoft Office (GSSMO)

This plug-in tool from Google for Microsoft Outlook does not use IMAP or POP3 settings. Consider it IMAP on steroids.

If you will be using GSSMO, please go to the Microsoft Outlook Setup page.

Comparison: IMAP and POP3

Site - Comparison: IMAP and POP3

IMAP (Recommended)


Important #1: By default, IMAP (and POP3) connections for Google accounts are disabled. Unless IMAP is enabled, Google will reject any attempt to set up IMAP in an email client. Update this setting by going to your online Inbox and select Gearbox > Settings > Forwarding and POP/IMAP, enable IMAP and then Save Changes.

Important #2: Some email clients do not meet Google's security standards and Google will block the attempt for the email client to connect. To overcome this problem, you will need to enable Google's "Less secure apps" setting online. Refer to this Google support page for more information and instructions.

IMAP - Details

Many clients will automatically configure the appropriate IMAP connection settings for your account, but confirm that the connection settings your client configures are the same as what's listed below.

If you're using a client that's not listed above, you can also use the following information to configure your IMAP. If you have problems, contact your mail client's customer support department for further instructions.

  • Incoming Mail (IMAP) Server - Requires SSL
    • imap.gmail.com
    • Port: 993
    • Requires SSL:Yes
  • Outgoing Mail (SMTP) Server - Requires TLS
    • smtp.gmail.com
    • Port: 465 or 587
    • Requires SSL: Yes
    • Requires authentication: Yes
    • Use same settings as incoming mail server
  • Full Name or Display Name: [your name]
  • Account Name or User Name: your full G Suite address (username@your_domain.com)
  • Email address: your full G Suite address (username@your_domain.com)
  • Password: your G Suite password

If your client does not support SMTP authentication, you won't be able to send mail through your client using your Gmail address.

POP3

Use POP3 as a bottom-of-the-list choice.

Important #1: By default, POP3 (and IMAP) connections for Google accounts are disabled. Unless POP3 is enabled, Google will reject any attempt to set up POP3 in an email client. Update this setting by going to your online Inbox and select Gearbox > Settings > Forwarding and POP/IMAP, enable POP. It is SIL's strong recommendation that you do not use Google's default setting for "2. When messages are accessed with POP". We strongly recommend the last option: "delete Your Organization Mail's copy". (Read our article about this here.) When done, Save Changes.

Important #2: Some email clients do not meet Google's security standards and Google will block the attempt for the email client to connect. To overcome this problem, you will need to enable Google's "Less secure apps" setting online. Refer to this Google support page for more information and instructions.

POP3 - Details

Incoming Mail (POP3) Server - requires SSL:

  • pop.gmail.com
  • Use SSL: Yes
  • Port: 995

Outgoing Mail (SMTP) Server - requires TLS or SSL:

  • smtp.gmail.com
  • Use Authentication: Yes
  • Port for TLS/STARTTLS: 587
  • Port for SSL: 465

Server timeouts: Greater than 1 minute, we recommend 5

Full Name or Display Name: [your name]

Account Name or User Name: your full email address (including @your_domain.com)

Email Address: your email address (username@your_domain.com)

Password: your G Suite password

Unless you're using recent mode to download mail to multiple clients, make sure you've opted not to leave messages on the server (This is an online email setting). If you do not, you will download massive quantities of email again, despite having already deleted much of this email earlier. Access your Forwarding and POP/IMAP settings and change your "When messages are accessed with POP" to "delete Your Organization Mail's copy".

If your client does not support SMTP authentication, you won't be able to send mail through your client using your Gmail address.

If you're having trouble sending mail but you've confirmed that encryption is active for SMTP in your mail client, try to configure your SMTP server on a different port (465 or 587).

Username and password not working? Some apps require you to also turn on access for "less secure apps" before setting up POP/IMAP connections.
