Migrate IMAP to Office 365 Mailbox

The Cigrati IMAP to Microsoft 365 Tool enables direct migration of emails from any IMAP-supported email client into Office 365 mailboxes.

safe-and-secure

Secure IMAP Account Login

It allows users to securely connect their IMAP email accounts within the software environment. The authentication process follows standard IMAP security protocols, ensuring safe access to mailbox data. This helps maintain data confidentiality and provides a reliable connection channel during the entire migration operation.

delete-duplicate

Duplicate Email Removal

The software automatically identifies duplicate emails by analyzing key attributes such as sender details, subject line, and message body. This prevents redundant entries in the destination mailbox, ensuring a clean, organized, and optimized Office 365 environment after the migration is completed successfully.

This feature enables the tool to detect and skip emails that have already been migrated in earlier sessions. It helps avoid repeated data transfer, reduces processing time, and ensures efficient migration by only moving new or unprocessed mailbox items to the Office 365 account.

These filters provide better control over migration, ensuring that only specific and relevant emails are transferred according to user-defined criteria.

Date Range Filtering

Users can define a specific time period using start and end dates to migrate emails within that range. This feature is particularly useful for partial migrations, compliance needs, or extracting historical data, ensuring precise control over which emails are transferred to Office 365.
