Compatibility Offered to Ease the OST to Microsoft 365 Migration

The tool is developed considering both technical and non-technical users. It converts to different formats or migrates OST files to Office 365, IMAP servers, etc without issues.

Subject lines, message body, hyperlinks, inline images, and font formatting are retained wherever the selected output format supports them. The email content can only be preserved using this professional tool.

During the OST to O365 migration, transfers contact records along with other mailbox items. It helps preserve available contact details, such as names, email addresses, phone numbers, and other saved information.

Images, documents, spreadsheets, PDFs, and other files attached to the original emails are converted along with the messages. These attachments can also be excluded or converted separately as per user needs.

Sender and recipient details, timestamps, headers, and subject data are retained so the converted files still reflect an accurate email history. If users want, they can also exclude timestamps when naming files and can set different names.

The original folder hierarchy is kept intact in the output, so converted mailboxes stay organized as before. This reduces the manual effort of restructuring those folder hierarchies from the start

Folders such as Trash, Spam, Sent, etc., are also migrated with custom user-defined folders and archived OST data. This is helpful in scenarios where users have old archive files and want to store them separately.
