Migrate MBOX emails to Exchange Server, IBM Domino, Novell GroupWise & Office 365

Email Migration, by

IT administrators sometimes will have to import email files (of their employees) to the organization’s email servers – Exchange Server, IBM Domino, Novell GroupWise, or Office 365. This situation usually arises when employees work from home on their own systems. It is easy to import the files of the email clients supported by the email server – e.g., importing Outlook PST files to Exchange Server. However, importing MBOX files (of email clients like Thunderbird) to Exchange Server or other email clients is difficult. For that, administrators will have to use professional tools like Kernel for MBOX to PST.
