Exchange 2016 mailbox quota not updating
The configuration change does not take effect until the cache is refreshed.
The default interval for refreshing the cached mailbox information is two hours.
Problems resulting from editing the registry incorrectly may not be able to be resolved.
The changes will be applied soon based on the database size and number of mailboxes.After you configure the mailbox size restriction for a mailbox, that mailbox user can continue to send and receive messages that cause the mailbox to exceed the configured mailbox size.The configured limits are enforced after a period of time, but do not take effect immediately.Important If you set the cache refresh intervals to very low values, you may affect the performance of your Exchange server.We recommend a value of 20 minutes for refreshing the mailbox information.
