SysTools Office 365 PST Import Tool

Why Go For PST to Office 365 Migration?

Why Manual Solution Fails ?

  • The manual techniques are region specific. If the Import PST service is not available in your region, it displays a message stating The Import PST Service has not been rolled out yet. Please check back after rollout is announced”.
  • If you want to upload PST files into Office 365 user account, you need admin permissions. Likewise, you must have Mailbox Import Export role access permission to import PST files.
  • If a PST file contains a mailbox item larger than 150 MB, the manual process will skip that item during the import process.
  • During the import process, you need to store PST files to some temporary storage such as hard disk. Then you must ship the hard drive to Microsoft. The process is really lengthy and may takes several days to complete.
  • You are not allowed to import a PST file containing 300 or more levels of nested folders.
  • The process of manual importing of PST files into Office 365 accounts is quite time taking. It provides a upload speed of 16.7 MB/min or 24 GB per day.
  • The cost of using Drive Shipping for uploading PST files into Office 365 account is $2 USD per GB of data.

Where Office 365 Import Tool Wins ?

  • You are allowed to use this software in any region without any limitation to import PST to Office 365 mailboxes. It is not region specific.
  • This application does not require any particular permission to migrate PST file to Office 365 user account.
  • The software does not skip any item from PST files during the import process. No limitations are imposed on the size or type of files that can be imported using the Office 365 Import tool.
  • It is independent of Outlook application also. You are allowed to transfer PST to Office 365 without Outlook installation on the local machine.
  • This tool is designed in a manner that it imports PST files of any size without any file size limitation.
  • Compared to manual methods, this tool offers quite a good transfer speed, i.e., 42 MB/min or 60.5 GB/day.
  • There is no additional cost charged for importing multiple PST files (unlike other manual methods where cost depends on file size.)
  • Apart from all this, the credentials entered by you remain totally safe. They are for import process only and not shared outside of your local machine.
