Our NOC Team have reported that some users have had success by logging into Outlook Web Access in order to gain access to their email.
If your Outlook program still halts at "Loading Profile", then you may want to attempt online access by visiting the following web link: https://outlook.office.com
You will be prompted for your username (email address) and password. Technicians have reported a ~50% success rate logging users in.
This is a work around at the moment - not a solution. We will update you further once we have been notified of progress by Microsoft. It should be noted that this is a Microsoft wide issue and not related to Compusult tenants specifically.
