ElephantsPlan the route. Validate both sides. Migrate with evidence.
Connect a compatible hosted IMAP service and migrate selected mailboxes into prepared Microsoft 365 destinations with monitored, resumable processing.
Migration orchestration—not permanent data storage.
From connection to verified results
IMAP source requirements
The provider must expose a resolvable IMAP hostname and permit mailbox or app-password authentication. Implicit TLS on port 993 with a valid server certificate is the recommended configuration.
Microsoft 365 readiness
Map each source mailbox to a licensed Exchange Online destination. Confirm mailbox creation, capacity and effective application access before starting the batch.
Checkpointed mailbox transfer
ElephantsData records per-user progress and durable checkpoints so supported retries can continue from accepted work. Exception reports keep skipped or failed items visible for review.
Protocol scope and limitations
IMAP exposes messages and folders, not a complete collaboration account. Contacts, calendars, rules, delegates, applications and native online archives are outside a standard IMAP copy.
