Since this morning I have been unable to connect my Outlook client to my mailbox, I received an email from the Office 365 Team that my mailbox had been successfully migrated over to the new system last night. Now when I originally configured Outlook and had to connect to the Exchange server using HTTP as the Autodiscover wasn't working so I don't know if that needs to be changed due to the upgrade? Webmail seems to work fine.
Any help is appreciated!
Thanks
