Common Migration Issues
- IMAP authentication fails at source: Verify the IMAP server address, port (typically 993 with SSL), and your full email address as the username. Some providers require an app-specific password when you have MFA enabled.
- Office 365 destination authentication error: Use OAuth or Modern Authentication for Office 365. Your Office 365 admin may disable basic authentication in your tenant settings.
- Some folders are missing after migration: The source IMAP server may use non-standard folder names. Check your migration tool’s folder-mapping settings and manually map any custom folders before starting.
- Migration stops midway for large mailboxes: IMAP servers and Office 365 both throttle connections for heavy transfers. Use incremental migration mode so the tool resumes from where it left off.
- Do I need admin access to migrate IMAP email to Office 365? For personal mailbox migration, your own credentials are sufficient. Moreover, bulk migrations of multiple users require admin access.
- Will my original IMAP emails be deleted after migration? No. The migration copies emails to Office 365. Your original IMAP emails remain unless you delete them manually.
- Can I migrate multiple IMAP accounts to Office 365 at once? Yes. An admin-level migration tool supports batch migration of many IMAP accounts simultaneously.
- Will folder structure be preserved after migration? Yes. A good migration tool maps IMAP folders to Office 365 folders to preserve the original structure.
- How long does an IMAP to Office 365 migration take? The time depends on mailbox size and internet speed. Large mailboxes may take several hours or more.
