retention question
Hello Experts,
I have a client who is looking to change the default retention settings for deleted items and deleted mailboxes from the default values 14 and 30 to 365 days each one. see screenshot attached for details
Since I have 50 databases, with different names, I wonder if you can provide a PowerShell cmdlet to automate this task, instead of performing manually this task from EAC. so given a CSV input file, with the database names, can we change these settings for all the databases within the file at once?
Can you please also respond following questions?
what service should be restarted on each mailbox after changing these settings?
What is the service impact of this change?
Thanks in advance

There will not be any major service impact, you just need to take care of storage capacity, in case if you are planning to retain deleted mailboxes for 365 days or more than 30 days.

so the correct cmdlet will be?
get-mailboxdatabase | Set-MailboxDatabase -MailboxRetention 365.00:00:00
Should I restart any Exchange service on the Mailbox server?
get-mailboxdatabase | Set-MailboxDatabase -MailboxRetention 365.00:00:00
Should I restart any Exchange service on the Mailbox server?
No need to bounce any service.

can you please this command works for Exchange 2013? and has the 365 day of the year?
get-mailboxdatabase | Set-MailboxDatabase -MailboxRetention 365.00:00:00
get-mailboxdatabase | Set-MailboxDatabase -MailboxRetention 365.00:00:00

You can do one more thing apply it with CSV file.
I have attached a CSV file in which you can provide DBName,
1. don't delete First line named "Identity"
2. Replace DB01 and DB02 with your Prod DB names as you have 50 DBs so you can hit a enter then put DB name e.g.
Identity
DB01
DB02
DB03
DB04
Keep this CSV file in a folder and change your working directory in Powershell.
Now below command will import CSV with DB names and change retention period:

Hi Amit, the command above worked, however only changed the deleted mailboxes and set to 365, the deleted items still shows 14 days
Any ideas on why?

Deleted Item retention is diff. attribute, sorry I forgot to tell you to change procedure for that. Please find below mentioned.
You just need to replace -MailboxRetention with -DeletedItemRetention
Set-MailboxDatabase -DeletedItemRetention 365.00:00:00.
