Office 365 IMAP migration between tenants
Hello,
i've an issue performing bulk IMAP migration of Office 365 mailboxes from one teannt to another.
I need to move mailboxes using migration admin account, for that i provided FullAccess rights to the admin account on all mailboxes to migrate:
Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'UserMailbox')} | Add-MailboxPermission -User AdministratorAccount@mydomain.com -AccessRights fullaccess -InheritanceType all
No problem with connecting to exchange online, creating endpoint, batch
the csv file foramt is:
targetmailbox_email,admin_email\source_email_ID,admin_password
the csv format file is correct ? i can't find any information regarding this on MS KB
Batch failed with this error :
Error: TooManyTransientFailureRetriesPermanentException/ImapTemporaryServerErrorException/ImapBadResponseException: Error: The job encountered too many transient failures (61) and is quitting. The most common failure is ImapTemporaryServerErrorException/ImapBadResponseException with the hit count 60. --> Imap server has encountered a temporary error. --> Imap server sent BAD response to ListCommand. Response code: '', message: 'User is authenticated but not connected.'.
Any ideas Please ?
Thank you.
I got the same error message when migrating a single mailbox with his password (inseated of using admin account)
I found the problem, my destination tenant has expired, I initially used https://cdx.transform.microsoft.com/ to create it and the 90 days expired now.
Thank you for your help
