I am trying to use this utility to move the emails/contacts/etc. in some of my local PST files into an email account on Exchange Online (the cloud) through Office 365.
I have set up the "Online Connection Settings" and have connected successfully using the "check" button to my Office 365 global administrative account.
Next I added my PST file using the "Add from Folder..." button.
The problem is that when I click on "Set mailbox..."( to direct the emails/contacts/etc. to be added to the correct email address in my company) the list never loads, it simply says "The Central Service is retrieving the mailbox data, try again in a moment".
It has been like this for several hours and shows no signs of change.
I need to be able to load .pst files from my old domain into the exchange cloud and NEVER USE THEM AGAIN. This means actually importing the emails, not just adding the .pst file to Outlook.
Please advise why the tool cannot find my company's email addresses and how to fix.

P.S: I have already posted this in the Office 365 forums, they gave me the "not officially supported" nonsense and sent me here.
