We just posted a new version of the Exchange Migrator which fixes a memory leak that occurred when exporting Office 365 mailboxes to PST files. The new version is also overall more reliable when exporting Office 365 mailboxes to PST. In our testing we’ve been able select all the mailboxes in an Office 365 tenant and export them to PST without issue. Give it a try and let us know what you think!
