Features of the tool to import OST files to IMAP account
Simplified process
The software comes with a simplified process to import OST emails to IMAP account with attachments. Users just need to download and install the software, add OST file and introduce IMAP account host address, username and password for authentication. These simple 4-5 steps take a few minutes to finish the conversion task without any hurdles.
Mass import of OST files
Without any complications, multiple OST files are imported at once to IMAP Server. OST files of inaccessible and password-protected nature are safely considered by the application. Moreover, users have options to convert selected OST mailboxes to IMAP Server. At the end of the migration, a log report is created containing details of the migration process to analyze it.
Scan and Items count
Before conversion, all added OST files are scanned by OST IMAP Migrator Tool and then a list of OST files with their numbers shown on the software interface. Users can get aware of the number of files and file structure in the preview pane. This helps users to effectively complete the conversion of OST items into IMAP Server with attachments and email attributes.
Protect original data of OST
All the data contained by OST file is not modified by the application while converting into IMAP account. The software keeps email components (to, cc, bcc, subject, from, date, time), email formatting (font styles, hyperlinks, font size, signatures, etc.) and attachments preserved during the migration task. Moreover, the default structure of OST file remains as it even after they are migrated to IMAP account.
No Outlook & Exchange Connectivity
The conversion of OST mailboxes to IMAP Server is completed without the installation of Microsoft Outlook and Exchange Server connectivity. Users can perform the conversion standalone with WholeClear OST 2 IMAP Converter. However, OST file created by all editions of Outlook is considered by the tool like Outlook 2019, 2016, 2013, 2010, 2007, etc.
