Hi there.

Do MS have a default blacklist that used on all 365 email a/c's

 

If so, do MS have a site to do a blacklist check . Ive seen links to blacklist removal forms , but no check tool

 

Ive looked in the more common Blacklist check sites, they all came out clean for this particular sender (email adress) . Not sure if
MS use any of those or they have their own .

They may not publicise this.  What's your scenario?

company with office365 (domain) email a/c's 
1 of their customers claims they have been sending emails (to them), emails not received .
Sender didnt receive any bounceback or non delivery message , so the email went somewhere

Its only this 1 sender whose emails never arrived (as far as we know)

 


Ran a deleted email recovery(via 365 Outlook web app) , & looked in there to see if it was actually received & deleted (not found in there)
Ran a email message trace (in 365 exch admin), nothing found from this one sender .
Did a search through inbox , junk etc : not found (via 365 Outlook web app)

 

365 admin is still very new to me, so any other suggestions on tracking down the missing emails ?
Ive asked to get that sender to send another email, so I can re-check in 365 Exch Admin.

Where was the client's email based before being moved to Office 365?

 

I have seen a scenario (more than once) where email was moved to a new ISP (or Office 365) but the DNS records and mailboxes at the old email hosting provider were never cleaned up.  As a consequence, any email senders using that same old provider were having their emails go into the old POP mailboxes that are no longer being checked (effectively into a black hole as far as the senders/receivers).

 

If the old email service provider is Spark's Telecom Business Hub, convincing the call centre rep there is an issue to be resolved is incredibly painful and time consuming.

Ah yes. The memories
I remember that issue with a (then) Telecom domain email a/c moved to another email host  undecided  Took so long to track down what was happening

If thats the case here, chances of getting it resolved are near zero (to be honest) . I'd have to liaise with the sender, the senders email host, get permission From
the sender to talk to their email host support (otherwise they wont want to know) etc etc
This sender isnt with Telecom spark, so not so likely

 

 

 

still working my way through 365 reports & email tracking. Awefull awefull system .

That sounds like the voice of experience similar to ours.  *chuckle*  One client asked us to give up with Spark and the Telecom Business Hub as the chargeable time was ticking along even though we were being conservative with charges.  Another client had the issue with a slightly smaller ISP who resolved the issue within 15 mins on the phone (I think it was Orcon).

 

Message Tracking in O365 isn't ideal, I agree.  One of my team is working through that now trying to explain some missing emails for a client.  We are wondering whether the missing messages were spam-filtered out by 3rd party systems Microsoft use before the Exchange Message Tracking system gets to log the email.  Of course there is no guarantee the sender's system actually transmitted the message.
