With MailStore's integrated IMAP server you can access the MailStore archive in read-only mode with any IMAP-enabled email client. This provides a convenient way to access the email archive using not only many alternative email clients on any operating system (e.g. MacOS or Linux), but also through email apps running on Android or iOS devices. Installing MailStore Client on the user machines is not required.

Prerequisite for Using the MailStore-Integrated IMAP Server

Activation and configuration of the integrated IMAP server are done using the MailStore Server Service Configuration. All IMAP-enabled email clients that support encrypted connections are supported, since the integrated IMAP server refuses the login over unencrypted connections.

Please note: When using Microsoft 365, Google Workspace or Active Directory Federation Services (AD FS) to authenticate users at login, accessing the archive via IMAP is not possible for technical reasons.

If Multi-factor Authentication is active for a user with MailStore integrated authentication, an App Password can be used for login.

If Multi-factor Authentication is enabled for a user with Directory Service authentication, that user will not be able to access the IMAP server.

Accessing the Integrated IMAP Server

Unless the integrated IMAP server is configured otherwise, users can access MailStore Server using the following settings:

  • Incoming Mail Server - Host name or IP address of the MailStore server
  • Port - For STARTTLS-encrypted connections (explicit TLS) the standard IMAP port 143 is used. For implicit TLS-encrypted connections the standard IMAP port 993 is used.
  • User Name - Name of the MailStore user.
  • Password - Password which is required for accessing the MailStore server. If Multi-factor Authentication is enabled for a user with MailStore-integrated authentication, an app password has to be used to authenticate.

Please note: In addition to configuring the incoming mail server, email clients often require configuring the outgoing mail server as well. In this case, using the same data as for an existing email account will facilitate further processing emails from the email archive.
