Retention policy for Teams
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 .

Hello ,
I read carefully all the reply . If I correctly understood , when a Team or O365 groups is deleted , the asssoicated sharepoint is not due to the retention policy applied on sharepoint (this is the behavior that I got) but the O365 groups are deleted, with a possibility to restore within 30 days . And if a retention policy has been activated , the content of the O365 groups or teams ( essentially the conversation chats and groupmail message) are retained somewhere and these data can be receovered via the eDiscovery .
Is this correct ?
Why Microsoft didn't implement a similar litigation hold status for the groupmailbox of the O365 group deleted ?
The ways I can see this , the groupmailbox is deleted , then put in litigation hold unlimited, it's becoming a inactiv groupmailbox. If required for investigation, then a new O365 group is created and we link again the O365 group to the groupmailbox and the data is accessible directly through a teams , etc . Much easier. At the moment it will be difficult to search for a specific O365 group or Teams deleted 1 or 2 years ago
At the moment I deleted a teams site ( 10 days ago deleted )which was containing emails, documents, conversation. I did a search via the eDiscovery and export the result to a PST file . Now I will see in 20 days ( after the 30 days) if I can find the message of the groupmailbox of this deleted O365 groups
benoitrando isn't the better point here that Teams is the same as SharePoint and the same as Exchange, you don't need to learn new skills.
