Apologies if this seems a bit of a dumb question but struggling to find a definite answer to the below
In our Security & Compliance centre there is a global policy which is set to retain everything for 5 years in Exchange
Within Exchange online there is a mailbox retention policy which is assigned as default to remove items over 2 years old (default assignment to whole mailbox)
The issue we have is we expected the mailbox to remove items still over 2 year old but be still kept on hold (just not visible by the user in the mailbox for 5 years) as part of the Security & Compliance global policy
In a users mailbox we can see items being tagged with the 2 year delete mailbox policy, but they never get removed.
Would this be the Security & Compliance centre stopping this or are the policies conflicting with each other and the longest retention is winning, hence why the items are not being deleted after 2 years?
We ran the Start-ManagedFolderAssistant against the mailbox which does apply the mailbox 2 year retention policy and tag them, just not getting removed. It's also been over 7 days since the mailbox policy was assigned.
