Disable the mailbox for users who are in a specific OU by the LastLogonTime parameter?

Question

Microsoft Exchange

Actually, this request does not work
Get-Mailbox -OrganizationalUnit "OU=users,DC=company,DC=ru" | GetMailboxStatistics | where {$_.LastLogonTime -lt (get-date).addDays(-90)} | Disable-Mailbox
What else could be an option?

Answer 1

Hello, the request itself works, but apparently, the logic messes up))
in the ekschencha, daily database maintenance climbs through the boxes under NT AUTHORITY\SYSTEM
and the backup also climbs according to its account.
all this is written in lastlogon, can it stupidly not find the account for the requirement?
