Turn POP and IMAP on and off for users
If your G Suite users want to use desktop clients, such as Thunderbird® or Outlook® Express®, to access their G Suite mail, you need to enable Post Office Protocol (POP) and Internet Message Access Protocol (IMAP) access in your Google Admin console. You can enable access for everyone in your account or only for users in specific organizational units.
Before you begin

- 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.
