IMAP/SMTP Settings for Common Providers

Configure Email Provider

MailDesk connects to your email account via IMAP (receiving) and SMTP (sending). Here are the settings for the most common providers.

Gmail / Google Workspace

• IMAP: imap.gmail.com, Port 993, SSL/TLS
• SMTP: smtp.gmail.com, Port 587, STARTTLS
• Important: You must create an app password (Google Account → Security → App Passwords). Your regular password will not work.

Microsoft 365 / Outlook

• IMAP: outlook.office365.com, Port 993, SSL/TLS
• SMTP: smtp.office365.com, Port 587, STARTTLS
• Important: IMAP must be enabled in the Microsoft 365 Admin Center. If multi-factor authentication is enabled, you need an app password.

Own Mail Server

• Ask your hosting provider for the IMAP/SMTP credentials
• Typical ports: IMAP 993 (SSL) or 143 (STARTTLS), SMTP 587 (STARTTLS) or 465 (SSL)
• Make sure the firewall allows the corresponding ports

Tip

MailDesk encrypts all passwords with AES-256-GCM before they are stored in the database. Your credentials are secure.
