Deprecation of the classic Exchange admin center in WW service

Hi,

Can you please help me clarify a few points.

Microsoft suggests “Use retention policies and retention labels instead of older features” were you refer to old features as the Exchange MRM.

You then further add:

“If you currently use these older features, they will continue to work side by side with Microsoft 365 retention policies and retention labels. However, we recommend that going forward, you use Microsoft 365 retention policies and retention labels to benefit from a single solution to manage both retention and deletion of content across multiple workloads in Microsoft 365.”

Older features from Exchange Online:

• https://docs.microsoft.com/en-us/exchange/security-and-compliance/messaging-records-management/retention-tags-and-policies, also known as https://docs.microsoft.com/en-us/exchange/security-and-compliance/messaging-records-management/messaging-records-management (deletion only)

However, if you use the following MRM features, be aware that they aren't currently supported by Microsoft 365 retention policies:

The Link itself: https://docs.microsoft.com/en-us/microsoft-365/compliance/retention?view=o365-worldwide#use-retention-policies-and-retention-labels-instead-of-older-features

My questions: What are Microsoft’s plans in terms of bringing the following features into MS 365 retention policies and labels:

1.  “An archive policy for archive mailboxes to automatically move emails from a user’s primary mailbox to their archive mailbox after a specified period of time.
1. Eg EAC uses a default retention tag to move all emails from primary mailbox to archive after 3yrs
2. The same ability when using retention tags within EAC to manage individual mailbox folders (Not referring to Personal Tags)
1. Eg Retention Tag: Delete mail from “Deleted Items” folder after 30 days or from “Junk Email” folder 

Or will this all move to PowerShell?

Many Thanks
