Use MAPI client

If this setting is checked, TreeSize will use the local MAPI client (for example Microsoft Outlook) for sending mails.

Use SMTP server

TreeSize will use the specified SMTP server to send email reports. Please make sure to test the connection settings before applying the current options.

Please note that you will have to enter valid SMTP settings in order to make use of email reports in scheduled scan or search tasks or all other kinds of automated starts (e.g. batch programs or command line calls) (Professional Edition only).


The email address that will be shown as the sender of the report.


The name (DNS) or IP address of the machine hosting the SMTP service through which messages are to be sent.


The port on which the SMTP service specified in the "Server" field is listening for connections.

Use secure (SSL) connection

Indicates that Secure Sockets Layer (SSL) should be used when sending messages via SMTP.

This server requires authentication

Select this option if SMTP service specified by the Server field requires authentication. Passwords will be encrypted before storing them in the TreeSize settings file.

Test Connection

Test the SMTP connection settings. This will send a test email to the email address specified in the "To" field.


Email body

Include results in mail body

Results will be added to the body of the email. NOTE: For very bigger reports, this can lead to very large mails, which can take a very long time to open in mail clients, or even exceed mail server limitations.

Attach a report with the results

Adds the result report as attachment to the email. This fixes the problem of very large emails that can occur with the other option.


Charts and lists to include

Folders and single files

If activated, single files will be exported as well. This may result in very large reports compared to exporting the files in a grouped view (see option above).

Use same columns as in details view

Activate this option if you want to use the same columns that are currently used in the details view.

Include units in export

If this options is activated, units like "KB", "MB", or "%" will be included in the exported data. Uncheck this option, if you want to export plain values.

Size unit
