Convert Outlook OST into PST format or Office 365 Mailbox

 

Outlook is one of the most used Desktop email client that is used to manage multiple E-Mail accounts from the single interface. It provides lot of features to the user for email management. Internally it stores the data of those emails into the OST file format when user connected with Exchange Server with Cached mode enabled. OST file is also created when a user configure IMAP accounts in Outlook 2013 or above versions. But an OST file can be accessed locally from the machine and becomes inaccessible when we try to use it with other profiles or accounts. Due to this disadvantage users are now migrating their data to the latest project of Microsoft i.e. Office 365.
