get-mailbox does not show all mailboxes

Hi,

i have test of Exchange 2013 SP1 CU7. Seems, that all works good. Users can login over OWA, send emails each other.

In ECP i see all 50 mailboxes. In powershell - only one! Why? how i can fix it?

[PS] C:\>get-mailbox -Identity "*"

Name                      Alias                ServerName       ProhibitSendQuota
----                      -----                ----------       -----------------
User 1                     User 1                 ex1              Unlimited

[PS] C:\>Get-Mailboxdatabase

base1                          EX1             False           None
all                            EX1             False           None

Thank you!
