MAAS IMAP Client Mode Error
Resolving fatal IMAP connection errors during migration.
Overview
Error Message
"Fatal error during migration process: MAAS Imap client mode ERROR"
Common Causes
Root Causes
Cause 1: Personal Email Accounts
The platform is designed to migrate company data, not personal data. Personal Gmail, Hotmail, and Yahoo accounts are not supported by this B2B migration solution.
Unsupported Account Types
Cause 2: Zimbra or IMAP Server Issues
When migrating from Zimbra or IMAP sources, verify the following:
- • The mailbox possesses a valid license
- • IMAP protocol is enabled on the user's mailbox
- • Server port configuration in the source connector is correct
Cause 3: Invalid Credentials
If user credentials provided through self-service mode are incorrect, the platform cannot establish a connection.
Solutions
For Personal Accounts
Cloudiway is a B2B solution. Personal email accounts (Gmail, Hotmail, Yahoo) cannot be migrated. Use a different migration solution for personal accounts.
For IMAP/Zimbra Issues
Verify IMAP is enabled for the mailbox, check port configuration (typically 993 for SSL), and ensure the account has a valid license.
For Invalid Credentials
Use the "Resend" button to allow users to re-enter their credentials correctly via the self-service portal.
