I've never seen an issue like this one! Can someone please offer some ideas?
Outlook 2016 connected to an Office 365 email account.
When the user opens Outlook 2016 it gets stuck on the blue "loading profile" screen.
However if the PC is being remotely accessed, either via VNC or TeamViewer 11, Outlook opens immediately without issue.
I have tried the following, but the issue persists:
Disabling Outlook add-ins
Recreating the Outlook profile
Removing VNC and TeamViewer
