If you are using the latest schemus version 1.52.03, and you received the following error: Invalid LDIF entry. Attribute expected
Exchange Online is returning a message which includes the text "Please install version 2.0.6 of the ExchangeOnlineManagement module" which is corrupting the results, hence causing the schemus to return an error when reading the data source.
Clients can install and upgrade their PowerShell to the latest version using the command :
Install-Module ExchangeOnlineManagement -Scope "AllUsers" -MinimumVersion "2.0.6"
Install-PackageProvider -Scope "AllUsers" -Name Nuget -MinimumVersion 188.8.131.52 Install-Module ExchangeOnlinemanagement -Scope "AllUsers"
