February 28, 20182.10Major Update

The purpose of this update was to introduce new mode of conversion called “Recovery Mode” which is dedicated to get as much data as possible from source file. In addition to that, we fixed issues that were noticed by our customers, our support or quality assurance teams.

Functional Updates

    "Recovery Mode" of conversion for both orphaned and connected OST files. When using this mode in addition to usual conversion OST2 does the following:

  • Un-hides items that are hidden in each folder of original file when saving them to destination;
  • Recovers items from "Deleted Items" folder to a folder named "Recovered_Data" in destination data storage;
  • Gets "First Name", "Last Name" and "E-mail Address" information from each Calendar item if they are present and creates corresponding Contacts in the "Recovered_Data"/Contacts;

Issues Fixed

OST2 Issues:

  • Conversion would get stuck on 5% of progress and would not finish; Several cases are known when this could happen and they are now handled differently, corresponding error message is shown.
  • Items, converted from OST to PST file, were empty (Outlook 2003 only);
  • Filters would not work when transferring items from orphaned .PST file to new .PST file;
  • “No files connected to Outlook were found" message would be shown when "Scan Outlook..." button is clicked (only for “Fall Creators Update” Outlook 2016 x64);
  • PST file would not get created after conversion, error icon and "Conversion completed successfully" status is shown (only for “Fall Creators Update” Outlook 2016 x64);
  • OST2 would remove the prefix “\\?” in Outlook data files path, which would make conversion not to work;
  • Duplicates of default folders would be created in destination when converting orphaned IMAP “This computer only” folders;
  • User could deactivate OST2 if he made 2 orders and one of them is more than 2 weeks old;

June 15, 20172.00Major Update

The purpose of this update was to introduce completely redesigned OST2 Wizard like User Interface. By implementing this new Wizard, we wanted to put every user who downloads OST2 on right tracks straight away – offering right start for each use case from the Step 1 of OST2 Wizard right till the end.

Functional Updates

  • The improved Wizard - user can choose what is best for him and start Conversion, Migration or Transfer, follow simple Wizard and check the status of Conversion or Transfer in the last Step. Together with this, second goal was to seamlessly integrate OST PST Viewer and Safe PST Backup so that after conversion user has an option to either open file he just received or setup backup scenario (they still would have to download and install those tools).

Issues Fixed

OST2 Issues:

  • After activating OST2 you do not need to restart the tool for activation to take affect
  • Sometimes Contacts/Calendars/Notes were placed into wrong folder ("Drafts") in converted PST file, depending on orphaned OST file Outlook version
