Below I will walk you through how to add an email account to your ONLYOFFICE deployment. First you’ll need an instance of ONLYOFFICE running (which I demonstrated in the previously-mentioned article) and the details for the email account you wish to use. ONLYOFFICE supports both IMAP and POP protocols (which means you can also add your Gmail Account, as long as you have IMAP support turned on and an app password created). Let’s walk through adding an email account to ONLYOFFICE.
Access the email account add wizard
1. Log in to ONLYOFFICE
Open ONLYOFFICE in your web browser with a user account that needs to have the email account added (you don’t have to be the admin user to do this).
2. Open the mail account wizard
Once you’ve logged in, click the email icon near the top right of the window (Figure 1). This will bring up the email account wizard tool (Figure 2).
3. Configure your email account
Click Add New Account and, in the resulting window (Figure 3), click Advanced. You can try to just type your email address and password to see if your email account works with autodiscovery. If so, type your credentials and click Add Account. If it doesn’t work, you’ll have to open the Advanced window (Figure 4) and add all of the necessary information for the account. After filling out the details for your email account, click Add Account, and ONLYOFFICE will connect with your mail server and popup to let you know the account has been added (Figure 5). Click OK, and you’ll be directed to the ONLYOFFICE email app, where you can start working with your email.
For Gmail accounts
For those who want to add a Gmail account, you’ll need to first enable IMAP in Gmail > Settings > See all settings > Forwarding and POP/IMAP > IMAP access. Once you’ve taken care of that, here are the settings you need to use. Incoming email:
imap.gmail.comPort: 993Authentication type: Simple passwordLogin: Gmail addressPassword: Your Gmail password. If you have 2FA enabled for Gmail, you’ll have to use an App Password (create one in your Google Account under Security > Signing into Google > App Passwords).Encryption for IMAP Server: SSL
Outgoing email:
smtp.gmail.comPort: 465Authentication type: Simple PasswordLogin: Your Gmail addressPassword: Your Gmail password. If you have 2FA enabled for Gmail, you’ll have to use an App Password (create one in your Google Account under Security > Signing into Google > App Passwords).Encryption for IMAP Server: SSL
Click OK, and your account is ready. Congratulations, you’ve just added an email account to ONLYOFFICE, so now you’re closer to having a drop-in replacement for Google Workspaces on your local network.
