Frequent Visitor

hello,

 

Use case: user A invites users B and C to an appointment.

 

Users B and C sync the appointment, all ok

When User A change anything in the appointment, C receives correctly the update, while the comunication to B failed and A receives an error message like this:

 

Authentication-Results: spf=permerror (sender IP is x.x.x.x)
smtp.mailfrom=xxx.xx; xxx.xx; dkim=none (message not signed)
header.d=none;xxx.xx; dmarc=none action=none header.from=xxx.xx;
Received-SPF: PermError (protection.outlook.com: domain of xxx.xx used an
invalid SPF mechanism)

 

Could you help me?
