Cannot receive calendar invitations, but email is fine from specific domain

Morning,

I have an interesting query where we happily receive our clients emails, but not his calendar invites.  I cannot see why not for the life of me.

We use Exchange 2010, we route our email through Symantec Cloud/Message Labs and have Sophos Pure Message installed as well.

Looking at the Symantec Cloud Track and Trace Logs, the invites are rejected by our Exchange server:

I cannot see why email from same sender is accepted, calendars are not.

Below is email delivery from same sender to same recipient:

What email software used by your client. I remember same issue, where calendar invites are stuck or failed to delivery. You need to ask client to check at their end.

Hi - they are using Lotus Notes!  I have asked the client to check their end too.

Ask them to sent a test invite to your public account like Gmail or Yahoo that can confirm where is the issue.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Yes - invitations reach other recipients, we receive other calendar invites - just not from this one domain.  We do get their email though.

All fixed - our Watchguard IPS was denying the mail with calendar attachments from the specific domain.
