Hello Experts,
Recently we have noticed that in one of our exchange server all the mailboxes has lost access to one of our admin account.
To tackle this issue temporarily, I have used the following power-shell command:
Get-Mailbox -Database “Server\Database” | Add-MailboxPermission -user 'accountname' -AccessRights 'FullAccess' -InheritanceType All
This command has added the admin user on full permissions to all the mailboxes on the server, but when I create new mailbox on the server, the admin account is not getting added on full permissions for the new mailbox.
I request your help to get help and troubleshoot this issue.

The permissions inheritance and the permissions will appear only after the creation of mailbox. The mailbox will be created only after we send an email to the mailbox or try to access the mailbox. This behavior occurs because the mailbox security descriptor is not read from the Active Directory account object until the user logs on or gets mail. The Recipient Update Service does not stamp the inherited permissions when the mailbox is created. After the mailbox is created in the store, the store calculates inherited mailbox rights.
