I am trying to migrate the archive from mimecast to office 365 archive folders. We have got all our .emls in a disk and we used a tool to convert them to psts. Now I am using the pst capture tool to move these psts to the archive in office 365 and i am getting the erro
Import error: The specified folder could not be found in the store.
Does anyone know what could this be related to? I was able to move one mailbox to the archive folder with no issues. I have given organization management to both the online admin and on premise admin. full mailbox perms too. all other mailboxes are failing with this error. Tried with MS support and they said they dont support pst capture tool . could anyone please help?
