Hello,
We have 2 users in the company that are not receiving emails generated by accounts that are set up On-Premise.
When I looked in the Queue Viewer, there were about 100 emails in that queue all addressed to them with Message Delayed error.
Everyone else in the company don't have any issues.
I compared the recipient lines for the successfully delivered messages with theirs.
Successfully delivered had the following:
Recipients: firstname.lastname@ourcompany.com;2;0;[{LRT=};{LED=};{FQDN=};{IP=}];0;;0
The error ones had the following:
Recipients: firstname.lastname@ourcompany.COM;2;2;[{LRT=};{LED=};{FQDN=};{IP=}];0;CN=Out to Office365,CN=Connections,CN=Exchange Routing Group (somestuffhere1),CN=Routing Groups,CN=Exchange Administrative Group (somestuffhere2),CN=Administrative Groups,CN=Ourcompanyname,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=Ourcomapnyname,DC=Com;0
They also had different Source IP addresses and Queue ID.
Also, I'm new at this, any help would be appreciated.
Tatyana
