IMAP Migration Zimbra to M365

Question

Hello,

to create the CSV file of user mailboxes using admin credentials to access them, which format of UserName column supported by Zimbra?

According to the documentation below, the supported format for mailbox admin credentials is different depending on source email system :

Anyone already did a migration from Zimbra IMAP system using admin credentials to access user mailboxes?
