Hi All,
Did you come across “Authenticated Received Chain (ARC)”?
Authenticated Received Chain (ARC) is an email authentication system designed to allow an intermediate mail server like a mailing list or forwarding service to sign an email’s original authentication results. This allows a receiving service to validate an email when the email’s SPF and DKIM records are rendered invalid by an intermediate server’s processing.
ARC is defined in RFC 8617, published in July 2019, as “Experimental”

Today i helped a Collegue with an Exchange Online Folderpermission Problem. He could not remove the Permissions from a Mailbox Folder (MAPI Permission).

Remove-MailboxFolderPermission -Identity email@domain.tld:\Kalender -User CH_DE_Room_Equipment_Reviewer This resulted in the following Error: Microsoft.Exchange.Management.StoreTasks.UserNotFoundInPermissionEntryException | There is no existing Permission entry found for user

It had served me for several years. The leather Polster of the earprotection already ripped - but was fixed with glue.
