When you assign full access rights to a mailbox, you may notice that the change does not take effect immediately, and the user that has been granted permissions to a mailbox still cannot access that resource. This is because the Information Store service uses a cached mailbox configuration that by default is only refreshed every two hours. You can force the cache to refresh by restarting the Information Store service on the mailbox server that is hosting the active database where the mailbox resides.

Get-Mailbox -identity ‘user@domain.com’ | fl name, grant*
