Hi there, going round in circles over this issue.
Firstly, I know of two ways to import our .PST files to our newly setup office 365 accounts (assume this uses exchange 2013??). The first is using the tool PST Capture - This gives me the same (unresolved) issue posted in other topics - where it cannot see any mailboxes on the server to import too.
The second is manually in powershell. I have zero experience prior to spending all day yesterday researching online how to make the transfer .
I have managed to get as far as connecting to our exchange server. However I am unable to run the command I believe needed to do the import (new-mailboximportrequest). I have added myself to the role of "Mailbox Import Export" but despite this I still cannot see it in the list of available commands.
