Add your business email to the Gmail app on your Android phone or tablet.
Gmail will then ask for the incoming and outgoing mail settings.
You can find the current server details for your mailbox in your Client Area.
For incoming mail use:
Account type: IMAP
Port: 993
Security: SSL/TLS
Username: your full email address
Password: your mailbox password
For outgoing mail use:
Port: 465
Security: SSL/TLS
Sign-in required: Yes
Username: your full email address
Password: your mailbox password
Make sure the outgoing username and password are entered even if Gmail looks like it might let you continue without them.
Once the account has been added, Gmail will ask about things such as:
Choose the options that suit you and finish the setup.
Don’t just check that your inbox appears.
Send a test message to another email address, then reply to it.
That confirms both incoming and outgoing email are working.
Don’t switch off encryption or accept an untrusted certificate just to make the warning disappear.
Check:
If the warning keeps appearing, send me a screenshot of the error.
If you’ve recently changed the mailbox password, Gmail may still be trying to use the old one.
Update the password for both incoming and outgoing mail.
If the same email address is connected to other phones, tablets or computers, they may need updating too.
The exact buttons and menu names will vary between Android phones and email apps.
The important details are the same:
These instructions add your mailbox to the Gmail app. They do not move your email into Gmail or turn it into a Google Workspace account.
Tell me:
A screenshot usually helps.
Don’t send me your password or screenshots containing private email content.
