Check which database the mailbox is created and then which server is holding that database now. Since you are using DAG, database may fail over to the SRV1 server in case any issue with SRV2.

All mailbox databases currently have their active copy on SRV2, yet some mailboxes are showing SRV1 as their server. &nbsp;It's only a handful but still very puzzling.

Although the link appears to be referencing Exchange 2013 I haven't been able to come up with a better answer and this would appear to be the case. &nbsp;Thanks for the help.

Currently we are using 2 Exchange 2013 servers to host our mail. &nbsp;I have set up a Database Availability Group (DAG) between both servers (I will refer to them as SRV1 and SRV2). &nbsp;I was using the Get-Mailbox cmdlet and noticed a strange discrepancy. &nbsp;<br />
<br />
Even though SRV2 is storing all active copies of our databases, some mailboxes are showing SRV1 as their server according to the Get-Mailbox cmdlet. &nbsp;Would there be a reason for this? &nbsp;I have created all mailboxes on SRV2, it just seems strange to me.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
