How to Archive Outlook Emails without PST

Archiving Outlook emails ensures better inbox space management as you move relatively less important messages to a separate folder or location. Even though Microsoft Outlook archives emails in PST as a part of its default operational functionality, you can archive email messages in other file formats as well, like HTML, MSG, TXT, EML, PDF, or RTF. The prime advantage of email archiving in these formats is that you can access archived emails using common applications like web browsers, MS Word, MS Excel, etc. Further, it is a proactive approach to retrieving valuable data in the event of PST file corruption.


Email archiving is beneficial for Outlook users in many ways. Firstly, it offers backup of vital data in case of PST file corruption.
