Hello. Since Microsoft announcement the retirement of Exchange In-place E-discovery and hold, we've been trying to figure out the their suggested alternative, Retention Policies in the Security and Compliance Center (Information governance).
Our intent is to use it for retaining a users Exchange data for 90 days after they've left the company, with the email being purged after the 90 days is up. It's the same function we had used EOL In-place hold for.
We'd like to setup the new policy so that it's assigned to a group instead of individual account mailboxes. From there, any accounts that were placed in the group would have the 90 day retention applied to it automatically. To clarify, this would be in Security and Compliance --> Information Governance --> Retention --> Create --> Choose locations --> Edit locations --> Exchange email --> Choose recipients.
When we tried to add an AD group at the "Choose recipients" screen, we were presented with a message that said only accounts currently in the group would have the policy applied. Any accounts added to the group after that would not have the policy applied.
Our question is, could we accomplish this using Office 365 Groups and/or Azure security groups? That is, the 90 day policy would be applied dynamically to an account/mailbox after it was added to the group.
Thanks in advance, and if this is the wrong forum for this post, please advise the proper forum to use.
