Exchange Server administrators need to be capable of managing a large number of users and their mailboxes. As the most common way to connect users to their mailboxes is through POP accounts, administrators need to be familiar with the process of managing these accounts and the messages contained in them.
The Exchange Server requires a dedicated Exchange Server installation and a SQL Server 2020 or later. Exchange Server features a rich database and multiple clients and can support twenty to thirty-five thousand users concurrently. This can be supported by Exchange Management Shell (EMS) commands.
The EMS scripts are responsible for the creation of a Microsoft Office Auto-Scaling Group (MS-AG) and must be used for this. This MS-AG is a group of servers, which is configured with Exchange Server as its home. One of the first things that administrators must do is configure the correct location and size of the MS-AG. A maximum of four servers can be placed in the MS-AG.
In order to create the MS-AG, an Exchange Server administrator will use the New-MailboxConfig cmdlet. The MS-AG must contain two additional servers, one is named Mailbox server 1 and the other is named Mailbox server 2. An MMC snap-in is used to create the MS-AG. It is not necessary to run MS-AG, as all required configuration has been done automatically by the EMS script.
After a proper configuration has been made, the EMS is used to assign the mailbox to the appropriate users and make it available to them. The user must also be assigned the name of the MS-AG. The MS-AG must have an email address that is in the same domain as the Exchange Server. The MS-AG must have an alias of a personal user that has the password on that mailbox.
The MMC snap-in should be used to open the MS-AG and place the email alias and the user name of the MS-AG. The Exchange Server admin is responsible for assigning the mailbox to the correct users and then the mailbox account must be created. The users who will be members of the MS-AG will need the password to authenticate themselves.
The mailbox that is to be shared with the MS-AG is created. The Exchange Server admin needs to supply the appropriate license for the mailbox. The MS-AG must have an autodiscover database, and a separate database for each mailbox. It is the responsibility of the Exchange Server administrator to maintain the autodiscover database for each mailbox.
After the Exchange Server has been configured, the MMC snap-in is used to manage the MS-AG. The MMC is used to add, delete, change the schedule, change the user settings, configure the settings and to remove the MS-AG.
The MS-AG can provide additional functionality by using an Exchange Server account with an email address and adding the password to the mailbox. Another important feature of MS-AG is the ability to give multiple email addresses to one user. This is useful when sharing email addresses among a group of users. This will prevent the user from having to select the email address of the person.
Before an MS-AG can be used, the Exchange Server administrator must configure the Autodiscover database for the MS-AG. The autodiscover database must contain all the information about the MS-AG that is required by the EMS script. The autodiscover database is used to help with the MS-AG migration process. This is important to ensure that all of the data in the MS-AG is correctly moved to the proper servers.
An MS-AG can also be used to monitor the health of the Exchange Server servers. These administrators need to be familiar with the right way to use the MS-AG and for troubleshooting situations when the MS-AG is not responding. They must be able to detect any problems that are occurring in the MS-AG and use the correct procedures to correct these issues.
