Hi
We currently use the IMAP migration tool in the exchange admin centre to migrate multiple 365 accounts from one tenant to another. With the deprecation of basic authentication this method stops working on tenants that have had it automatically switched off by Microsoft. Although it can be re-enabled this is only temporary until October when it is switched off for good. This being the case is there an alternative tool in the admin centre for migrating accounts or will something replace the current IMAP migration process in place/is there a way to use it with modern authentication?
Thanks
