Question 1

What is IMAP email migration?

Accepted Answer

IMAP email migration is the process of transferring emails from one IMAP email server to another. This includes copying all messages, folders, and folder structures between email providers like Gmail, Outlook, Yahoo, and any server that supports the IMAP protocol. Mailbox Taxi automates this entire process with a simple desktop interface.

Question 2

How do I migrate emails between IMAP servers?

Accepted Answer

With Mailbox Taxi, you simply select your source and destination email providers, enter your credentials, test the connection, and click Start. The tool handles all the complexity of IMAP synchronization, folder mapping, and message transfer. You can migrate between any combination of supported providers or custom IMAP servers.

Question 3

Is my email data safe during migration?

Accepted Answer

Absolutely. Mailbox Taxi runs 100% on your local desktop — your email credentials and messages never pass through any third-party cloud servers. The connection between your machine and the email servers uses the same TLS encryption as your regular email client.

Question 4

How long does an IMAP migration take?

Accepted Answer

Migration speed depends on the number of emails, their size (attachments), and your internet speed. A typical mailbox with 10,000 emails takes roughly 15–30 minutes. Mailbox Taxi's parallel processing feature lets you migrate multiple mailboxes simultaneously, significantly reducing total time for batch migrations.

Question 5

Can I migrate from Gmail to Outlook (or vice versa)?

Accepted Answer

Yes! Mailbox Taxi supports migration between any combination of its 10+ supported providers. Gmail to Outlook, Outlook to Yahoo, iCloud to Gmail — any direction works. You can also migrate to and from custom IMAP servers.

Question 6

Will my original emails be deleted after migration?

Accepted Answer

No. Mailbox Taxi copies emails from the source to the destination. Your original emails remain untouched on the source server. Think of it as a copy operation, not a move.

Question 7

Do I need technical knowledge to use Mailbox Taxi?

Accepted Answer

Not at all. Mailbox Taxi is designed for everyone — from IT professionals managing enterprise migrations to individuals switching personal email providers. The interface guides you through each step, and pre-configured provider settings mean you don't need to know IMAP server addresses or port numbers.

Question 8

Which email providers does Mailbox Taxi support?

Accepted Answer

Mailbox Taxi supports Gmail, Outlook/Office 365, Yahoo Mail, iCloud Mail, Zoho Mail, AOL Mail, ProtonMail (via ProtonMail Bridge), Fastmail, GMX, Yandex Mail, and any custom IMAP server. If your provider supports IMAP, Mailbox Taxi can handle it.

Question 9

Can I migrate multiple email accounts at once?

Accepted Answer

Yes. Mailbox Taxi supports batch migrations via CSV import. Prepare a CSV file with your account details, import it, and run all migrations in parallel. This is ideal for IT teams handling company-wide email migrations or MSPs managing multiple clients.

Question 10

What happens if the migration fails or my internet drops?

Accepted Answer

Mailbox Taxi has built-in crash recovery and pause/resume functionality. If your connection drops or the app crashes, simply restart and resume — it picks up exactly where it left off without re-downloading emails or creating duplicates.

Question 11

Does Mailbox Taxi work with custom IMAP servers?

Accepted Answer

Yes. Beyond the 10+ pre-configured providers, you can connect to any IMAP server by entering the hostname, port, and security settings manually. This works for self-hosted servers, corporate email systems, and niche providers.

Question 12

How much does Mailbox Taxi cost?

Accepted Answer

Mailbox Taxi will be a one-time purchase with no per-mailbox fees, no monthly subscriptions, and unlimited migrations included. Join the waitlist to be notified when pricing is announced and to lock in early access benefits.

Question 13

Does Mailbox Taxi work with ProtonMail?

Accepted Answer

Yes, through ProtonMail Bridge. ProtonMail Bridge is a free desktop app from ProtonMail that provides local IMAP access to your ProtonMail account. Once Bridge is running, Mailbox Taxi connects to it like any other IMAP server.

Question 14

Will my folder structure be preserved during migration?

Accepted Answer

Yes. Mailbox Taxi preserves your complete folder hierarchy when migrating between servers. Your inbox, sent, drafts, and custom folders are all replicated on the destination server exactly as they appear on the source.

Question 15

What operating systems does Mailbox Taxi support?

Accepted Answer

Mailbox Taxi is a desktop application available for Windows, macOS, and Linux. It runs natively on all three platforms with the same features and performance.
