I am getting the attached error when trying to run through the following fix for Office 365 emails.
Open Powershell as an Admin
$UserCredential = Get-Credential
(input office 365 admin login details)
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
Set-RemoteDomain Default -TNEFEnabled $false
To confirm that the setting change was applied use:
In the returned results, look for: TNEFEnabled: False
The above fix is intented to resolve the winmail.dat problem that happens with some recipients when sending to btinernet accounts.
Is it possible someone would be able to shed any light on what this error means please?
Any help is appreciated.
