Change SMTP settings to check Gmail on other clients
You can read your messages from Gmail in other mail clients, like Microsoft Outlook and Apple Mail, using IMAP. When you use IMAP, you can read your Gmail messages on multiple devices, and messages are synced in real time. You can also read Gmail messages using POP.
Note: To avoid locking yourself out of your account, make sure you don't exceed 2500 MB per day for IMAP downloads and 500 MB per day for IMAP uploads. If you're setting up a single IMAP account on multiple computers, try taking a break between each setup.
Set up IMAP
Step 1: Check that IMAP is turned on
- On your computer, open Gmail.
- In the top right, click Settings .
- Click Settings.
- Click the Forwarding and POP/IMAP tab.
- In the "IMAP Access" section, select Enable IMAP.
- Click Save Changes.
Step 2: Change your IMAP settings in your email client
Use the table below to update your client with the correct information. For help updating your settings, search your email client's Help Center for instructions on setting up IMAP.
|Incoming Mail (IMAP) Server||
Requires SSL: Yes
|Outgoing Mail (SMTP) Server||
Requires SSL: Yes
Requires TLS: Yes (if available)
Requires Authentication: Yes
Port for SSL: 465
Port for TLS/STARTTLS: 587
|Full Name or Display Name||Your name|
|Account Name, User name, or Email address||Your full email address|
|Password||Your Gmail password|
If you can't sign in to your email client, you might see one of these errors:
- "Username and password not accepted"
- "Invalid credentials"
- You're asked to enter your username and password over and over
Step 1: Check your password
If you have these problems or can’t sign in, first check to make sure you’re using the right password.
Step 2: Try these troubleshooting steps
- Update your email client to the latest version.
- Use an App Password: If you use 2-Step Verification, try signing in with an App Password.
- Allow less secure apps: If you don't use 2-Step Verification, you might need to allow less secure apps to access your account.
- If you recently changed your Gmail password, you might need to re-enter your Gmail account information or completely repeat your Gmail account setup on your other email client.
- If the tips above didn't help, visit https://www.google.com/accounts/DisplayUnlockCaptcha and follow the steps on the page.
- The email client's sign-in method might be insecure. Try signing in directly on the Gmail app.
You can only use 15 IMAP connections per account. If you have many email clients getting messages from Gmail at the same time, you may see the "Too many simultaneous connections" error.
If you use multiple email clients or devices for the same Gmail account, try closing or signing out of some.
Try the options below if you see this error: "The server you are connected to is using a security certificate that could not be verified. The certificate's CN name does not match the passed value."
- Make sure you've set up your mail client for IMAP and not POP.
- Check your Incoming Server setting to make sure it says
You might be downloading too many emails at one time.
To fix this:
- Update your IMAP settings so you don't sync certain folders.
- Remove your Gmail account from your email client, then try adding it again.
- In your Gmail IMAP settings, set IMAP to only sync folders with 10,000 emails or fewer.
