Hello,
I dont' know if some of you already think about the governance of Teams and O365 groups ( Conversation, files , notes, etc). I'm currently testing it to see the real behavior.
I configured a Retention policy for each service ( Exchange online, sharepoint online, O365 groups, Teams ) . The goal is to keep all the DATA FOREVER as we are working in a financial institution.
As you know all , when you are creating a team site, a groupmail mailbox is created and a sharepoint site is created . Fine .
To see the groupmailbox of the O365 group and Team there are 2 ways :
Get-UnifiedGroup -ResultSize unlimited | select Displayname,name,*size*,manage*,recipien*,share*,accessty*,primary*,hidden*,GroupMemberCount | Out-GridView
or
Get-mailbox -GroupMailbox -resultsize unlimited
After applying the retention policy , I can't delete anymore any Sharepoint site ( Popup : Can't delete site : A compliance policy is currently blocking this site deletion)
Wonderfull .... I will keep all the sharepoint site and in case of legal and audit investigation, you can check
Now I'm trying to delete an O365 group or a Team Site .... and it's working . The team site is deleted.
I checked the associated sharepoint site and great the sharepoint site has not been deleted
Then I was looking for the groupmailbox ( get-mailbox -groupmailbox -inactivmailbox) ... the groupmailbox from this team site has been deleted . This means that in 30 days , I will lose all data conversation .
I got 2 questions:
1. Why the retention policy is not working for groupmailbox of teams and O365 . I have enabled the same FOREVER retention policy as the sharepoint once.
2. Is it a way to put the groupmail mailbox in a status "inactive mailbox" like for normal user and shared mailboxes ? I tried but impossible to set litigationhold to true ?
I'm really looking a way to keep any data from all O365 application in case of investigation .
The retention policy is not working as expected or I missed something . The sharepoint data are moved to the "Preservation Hold Library" when a document is deleted and the exchange recoverable items are working well as well .
Hope to get some feedback .
