Hello,
while downloading emails, the following message appears:
Could not download attachments. Skipping e-mail: AU2601705
Microsoft.Exchange.WebServices.Data.ServiceVersionException: The property Mentions is valid only for Exchange Exchange2015 or later versions.
In the HotMailBox configuration, there's no option to specify a dedicated configuration for Exchange On-premises. There's only an option for MS Exchange 2013/2016/2019.
I use MS Exchange in version 2019
