I want to migrate emails from Rackspace to Exchange online.
I referred to this document: https://learn.microsoft.com/en-us/exchange/mailbox-migration/migrating-imap-mailboxes/migrate-other-types-of-imap-mailboxes#format-mailbox-admin-credentials-for-different-imap-servers
I am able to migrate mailbox when I specify id and password in the csv file for migration. But I am not able to migrate when I try with using credentials of admin user of Rackspace account. Following are some of the formats that I have tried and failed.
EmailAddress,UserName,Password
myUser@myorg.com,myorg/myAdminUser/myUser,myPassword
EmailAddress,UserName,Password
myUser@myorg.com,myorg.com/myAdminUser/myUser,myPassword
I get following error for both of these formats.
Error: MigrationPermanentException: The username or password for this account is incorrect, or IMAP access is disabled. --> The username or password for this account is incorrect, or IMAP access is disabled. --> Imap server reported an error during LoginCommand indicating that authentication failed: 'Authentication failed.'.
I am looking for a valid csv format.
Thank you.
