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...
M_MAdmin... What happens when you migrate 1 mailbox instead of bulk at first instance? Test and you may see a more detailed error than while performing a Bulk operation.
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
