PST FILESPrivate preview

Bring PST files from every PC into Exchange Online

RealMigrator searches each profile for PST files, uploads them while Outlook keeps working, and after the final run hands each one to Exchange Online's own mailbox import, by default into the archive mailbox.

  • Search: the whole user profile
  • Target: the archive mailbox
  • Ready for multi-geo tenants
FINDING THEM

Where the client looks for PSTs

PST files live wherever someone once clicked "Save": in Documents, on the Desktop, three folders deep in a project archive. The PST catalog searches the whole user profile by default, and you can add any other folder. If you switch on the Outlook option of the inventory, each PC also reports which PSTs are attached to its Outlook profile, so the forgotten copies and the ones in daily use can be told apart. The upload report shows format, encryption and version for each file, so the unusual ones are known before import day.
Example data. Values as the report writes them: the format (ANSI or Unicode), the PST's own encryption setting and its format version.
UPLOADING

PSTs are uploaded while Outlook is open

A PST is large, and Outlook holds it open all day. RealMigrator uploads it to the project's Azure Blob Storage in blocks of 1 MB and, after the first pass, sends only the blocks that changed. Whatever Outlook has locked is skipped and read at the next pass. Before the final run the client asks every program to close, waits 5 seconds and ends the ones still running, and then reads the rest.

How a PST gets into the mailbox

The import starts after the device's final run and takes only the PSTs that are completely uploaded.
  • The final run ends.

    The PC reports that every PST is uploaded and its migration is finished.
  • One import request per PST.
    One import request per PST.
    RealMigrator hands each file to Exchange Online's own mailbox import, for the user's mailbox, into the archive mailbox unless you chose the primary mailbox.
  • Progress in the portal.

    The import reports show which requests are running, which failed and which succeeded, per user.
  • Cleanup.

    Finished requests are removed from Exchange Online (on by default). If an import needs another try, an administrator starts it again from the portal.
MAILBOX FOLDERS

Each PST gets its own folder

The mailbox shows where a PST came from, or puts every PST into one folder. Two PSTs with the same name never land on top of each other.

On the PC

In Exchange Online

  1. Archive mailbox
  2. PST from LAPTOP-0412
  3. Documents
  4. Outlook Files
  5. archive2019

OPTIONS

Import options

  • Archive or primary mailbox

    The archive mailbox is the default, so old mail stops crowding the primary mailbox. Switch it per project if users want their PST mail in the primary mailbox.

  • Multi-geo tenants

    For Exchange Online tenants configured for multi-geo, the import can respect where each mailbox lives.

  • Clean requests

    Finished import requests are removed from Exchange Online, on by default, so the next batch starts with a clear list.

  • Detach PSTs from Outlook

    A ready-made script from the documentation removes the imported PSTs from the Outlook profile after the final run, optionally to the recycle bin. Nobody opens the old copy by mistake.

Find out how many PSTs you really have

In the private preview, one group runs in Discover mode first, so you plan the import with the numbers of the PST reports instead of guesses. Access is by invitation after a short qualification.
