delete old items older then 30 days from user mail box (exchange 2013)

Hi,

I'm trying to run this command (exchange 2013), delete mails that are older then 30 days:

[int]$numberOfDays=30

[DateTime]$date=[DateTime]::Now.Subtract([TimeSpan]::FromDays($numberOfDays))

$m is the mailbox  identity.

$date is the date ,that mails that older or equal to  $date I want to delete.

I get this error:

Search-Mailbox : Could not load file or assembly 'Microsoft.Ceres.NlpBase.RichTypes, Version=16.0.0.0, Culture=neutral, PublicKeyToken
