Hi
Originally the Extented protection wasn't working properly if we used archiving policies from the link bellow.
Was this issue fixed and we can enable it?
An update to the Exchange Server Extended Protection script is now available - Microsoft Community Hub
This update includes an interim fix to work around a https://microsoft.github.io/CSS-Exchange/Security/Extended-Protection/#known-issues-and-workarounds with archive mailboxes when using retention tags, specifically:
Customers using a Retention Policy containing Retention Tags which perform Move to Archive actions should not configure Extended Protection, as enabling Extended Protection will cause automated archiving to stop working.
The updated script provides a short-term workaround for this issue, which will be permanently resolved in a future update. When the future update is released, the workaround in this updated script will need to be reverted after the future update is installed.
