As part of the Exchange 2016 upgrade, a new mandatory database is required on all user mailboxes. The new database stores vital information needed for the upgraded mail system to function.
While many users are eagerly anticipating the new features and upgrades of Exchange 2016, others are dreading the installation of the new database. Some have expressed concerns that this will result in decreased performance or even data loss.
At times, when you try to open the Exchange 2016 database on a user mailbox, you may get the following error: “Exchange 2016 database is mandatory on usermailbox.”
This can be caused by several factors, such as an incorrect installation or a corrupted mailbox. In this article, we’ll show you how to fix the error “Exchange 2016 database is mandatory on usermailbox.”
If you see the error “Exchange 2016 database is mandatory on usermailbox” while trying to access your Exchange 2016 mailbox, there are a few possible causes and solutions. Here are some solutions you can try:
One possible cause is that your Exchange 2016 server is configured to use a dedicated Exchange Database Availability Group (DAG). In this case, you will need to create a new mailbox database on the DAG and move your mailbox to that database.
To do this, follow these steps:
Once the mailbox has been moved, you can delete the old mailbox database. Moreover, you can also reset exchange mailbox password for an added layer of security.
Another possible cause is that you do not have an Exchange 2016 mailbox. In this case, you will need to create a new mailbox on an Exchange 2016 server.
If you receive the error “Exchange 2016 database is mandatory on usermailbox” while trying to create a new mailbox in Exchange 2016, it means that you have not yet created an Exchange 2016 database. To do so, follow these steps:
Finally, you will need to set the permissions on the database so that the users can access it. After this, you should now be able to access your mailbox. If you have any further issues, please contact your Exchange administrator.
One possible cause of this issue is that your Exchange server may not have enough resources to support additional databases. Moreover, if your Exchange Server is running low on resources, you may see the error “Exchange 2016 database is mandatory on usermailbox.”
This means that the Exchange server requires a database in order to function properly. You can either add more resources to your Exchange Server or optimize your Exchange Server to make better use of the resources you have.
