Good day,

Hope you are well.

Please help, we have a office 365 server. We have received an email containing 1 attachment on the web and outlook.

But the sender send an email containing more attachments. We also have software where we imported the email and saw that all the attachments was there.

Please advice as what can be the cause of this and how to fix it.

Kind regards
