Outlook 365 not connecting after email migration

We have connected our 365 tenant to the one in the US so we are all on the same platform for Teams etc.


I cannot get outlook to connect to 365 on our main ERP server.


Tried recreating the profile, reinstalling Office and changing Auto discover registry settings:

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover]
"ExcludeScpLookup"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover\RedirectServers]
"autodiscover-s.outlook.com"=hex(0):
"autodiscover-s.partner.outlook.cn"=hex(0):
"autodiscover-s.outlook.de"=hex(0):
"autodiscover-s.office365.us"=hex(0):
"autodiscover.hotmail.com"=hex(0):


I have also tried removing all identity entries under this reg key:

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Identities]


The above has worked on all out PC clients and another server with the same email account.


When I open Outlook it searches and finds the email address, I click connect then I get "Something went wrong" dialogue.


I have rebooted the server it did not help.


Can anyone help?

Thanks for this, looks like a good tool.

I did not get any errors but still cannot connect with the Outlook client. I can connect OK using outlook webmail...

My support company say the only way to recover is to delete the entire user profile on the server.
