Send Email to KanBo - Installation (OnPremise)

Last modified:

The Send Emails to KanBo feature will allow you to send emails directly to a KanBo Board and create a new Card out of the email. It will also allow you to add email and its attachments to an existing KanBo Card.


  • This feature is enabled for KanBo in version 2.7. Make sure you have this KanBo version installed.
  • Functionality requires having a service account on your Office 365 to serve as a Catch-All account. This Office 365 user needs to have at least Exchange Online license.
  • Optional - you can set up an email account for Incoming Email with a custom domain. Learn how to add a custom domain to your Office 365 here: Add a domain to Office 365. When you wish to proceed with a custom domain, create a service account with this domain in his email address (example: [email protected])

1. Creating a Catch-All email address.

You will need to create a Catch-All email account in your Exchange Online (in Office 365 installation scenario) or on Exchange server (in On Premise installation scenario).

This is a recommended scenario for creating a Catch-All address for Office 365/Exchange Online.

  • Add accepted domain in your Office 365.

Go to Office 365 and select Admin -> Exchange. As a next step, please choose the Email Flow in Exchange Admin Center.

  • Click on the  “Accepted Domains”, then select your domain and click on the edit button.

  • In the new windows, change  “Authoritative” to “Internal Relay” and save the changes.

  • Open Mail Flow section once again. Now select the Rules section and click on + (Add New button) and chose Create New Rule.

  • When the rule appears, select "More options..." at the bottom of the page. Give this Rule a name like "CatchAll".

  • Set the following properties to the Rule.
- In Apply this rule if chose "A recipient's domain is" - here add your domain.
- In Do the following chose "Redirect the message to" and then, chose your CatchAll Email account from the User Picker.
- In Do the following Add Action and select "Set the message header to this value..." and "Set the message header 'X-CatchAll-Rule' to value 'Yes'.
- In Except if... select "The recipient is..." and then, chose your CatchAll Email account from the User Picker.

Now save the Rule.

2. Creating a SSL certificate.

This is a recommended method for the IIS scenario. Please perform these steps on your Virtual Machine.

  • Go to the IIS and double click on Server Certificates.

  • Now click on Create Self-Signed Certificate.

  • Specify a friendly name for a certificate and select Personal. Click on OK.

  • Select the certificate and select Export.

  • Select the path and name for the certificate and add new password to it.

3. Changing KanBo web.config.

  • Move to the location where your KanBo backend is hosted (the KanBo package). Open the web.config in any text editor.

  • Add the following code into <Authentication> section. 

Change the CertificatePath to your local path to the certificate,

CertName with your certificate's name

and Password with your certificate's password.

<provider id="incoming-mails-svc" type="AppSignedService" name="Incoming mails">
<signer type="X509SignerFromFile" file="CertificatePath\CertName.pfx" key="Password" />
<provider id="incoming-mails-user" type="AppSignedUser">
<signer type="X509SignerFromFile" file="CertificatePath\CertName.pfx" key="Password" />
<provider id="incoming-mails-email" type="AppSignedEmail">
<signer type="X509SignerFromFile" file="CertificatePath\CertName.pfx" key="Password" />

  • Move slightly to the bottom to see the <appSettings> section.

- Set KanBoIncomingMail value to true.

<add key="KanBoIncomingMail" value="true" />

- Set KanBoIncomingMailDomain to your sending domain name - the one on which you have the Catch-All mailbox.

<add key="KanBoIncomingMailDomain" value="YourDomain" />

Save the web.config.

TIP: If you intend to send emails to your catch-all address and some other email addresses (multiple at once), add this entry and adjust the number inside it to match the maximum number of receivers.

<add key="kanbo.max-receivers" value="1" />

4. Configure the Email Tool

Contact us at [email protected] to receive an Email to KanBo tool package. 

  • Once you download the package, unzip it and move it a chosen location. In our case it would be C:\Email Tool\EmailToKanBo\EmailToKanBo .
  • Open your directory and start editing EmailToKanBo.exe.config

  • In the following section please change the following values:
[email protected] - add here your Catch All email

- Password - add here the Catch-All account's email

<add key="mail.type" value="ews-unread"></add>
<add key="mail.receiver-email" value="[email protected]"></add>
<add key="mail.receiver-password" value="Password"></add>
<!-- will autodiscover if empty -->
<add key="mail.url" value=""></add> 


  • In the next section, adjust the following values:

- CertPath - local path to your certificate,

- Password - your certificate password,

- https://YourKanboAddress - add here your KanBo address

- YourDomain - add here your email domain to which Catch-All address is connected to

<add key="kanbo.api.cert.file" value="CerthPath\CertName.pfx"></add>
<add key="kanbo.api.cert.pass" value="Password"></add>
<add key="kanbo.api.url" value="https://YourKanBoAddress"></add>
<add key="kanbo.incoming-mail-domain" value="YourDomain"></add>
Save the changes.
