There are several situations where Exchange administrator wants to export Exchange mailboxes to PST. However, an email often carries more than just a text message. An email may include lots of information in their attachments. Due to which the size of mailboxes increases. But, Exchange has a default size limit, so it creates a problem when mailboxes exceed the default size limit. Hence, people are looking for a solution to export large size EDB mailboxes from Exchange 2010 to PST format but they do not get. In this blog, we will try to resolve this problem.
