Using Classic Outlook on Windows for personal email, calendar, and contact management
Since classic Outlook connects but new Outlook stays on Wait, the most likely causes supported here are Gmail IMAP settings and Gmail folder visibility over IMAP.
Try this end-to-end check:
- In Gmail on the web, open Settings > Forwarding and POP/IMAP.
- Under IMAP Access, make sure Enable IMAP is turned on, then select Save Changes.
- In Gmail, open Settings > Labels.
- Make sure Show in IMAP is enabled for at least Inbox, Sent Mail, Trash, and All Mail. Enable it for any other labels that need to appear in Outlook.
- After changing those settings, refresh Outlook. The documented sync refresh can take up to 15 minutes.
If the account was added but password/authentication keeps failing in Outlook, an app password may be required for some account types instead of the normal password.
If setup in classic Outlook ever fails as well, manual setup is available for third-party mail accounts:
- In classic Outlook, go to File > Add Account.
- Enter the email address.
- Select Advanced options > Let me set up my account manually.
- Choose POP or IMAP.
- If needed, use these Gmail IMAP/SMTP settings:
- Incoming IMAP:
imap.gmail.com, SSL, port 993 - Outgoing SMTP:
smtp.gmail.com, SSL port 465 or TLS/STARTTLS port 587
- Incoming IMAP:
