The following instructions describe how to configure Clarity Service Management to connect and communicate with an Office 365 Server. 


Clarity Service Management 17.1
Clarity Service Management 17.0
Clarity Service Management 14.1


In order to properly configure maileater to connect to Office 365 Mail, please follow these steps:

1. We first need to obtain the proper SSL certificate for the Office 365 mail server.

Note 1:

As of Dec 2016, the Office 365 Certificate is signed by the "DigiCert Global Root CA". Information on this certificate can be found here. If gets signed by a different root certificate in the future, you would need to obtain the new root certificate from Microsoft or find out what the root certificate is and grab it from the vendor.

Information on acquiring the root CA using openSSL can be viewed here:

Note 2:

If the Certificate file name has format <name>.txt, it should be renamed as <name>.cer

2. After gathering the information for your root certificate, create a file using Notepad with the certificate's information.  For details on how to achieve this, please review the following tech article:

3. Save the file and copy it to the primary server and make note of the path.

4. Use the following settings in the mailbox details screen (making sure to populate your full email address and file path to the certificate that you saved):


To obtain your specific POP/IMAP settings and enable POP access:

  • Login to Outlook.Com with your existing mail credentials.

  • On the upper right corner of the Web UI, click on the gear icon to access Settings.

  • Search for "IMAP" and you will see a setting for "POP and IMAP".

  • Click on the "POP and IMAP" link.

  • The Sync email display will appear, and will expose the specific POP and IMAP settings you need to use:
