Do not deprecate Search-Mailbox
Do not deprecate Search-Mailbox or Allow New-MailboxComplianceSearch to delete more than 10 mails in a single mailbox.
when need to delete, as we did sometimes, more than 5.000 mails caused by mail loopings Search-Mailbox is the perfect tool.
eDiscovery limitations not allowing more than 10 emails to be deleted per command executive makes the eDiscovery a useless function.
We recently had a sensitive situation where an email was sent internally to 1000+ recipients, if we did not have search-mailbox functionality to clear these records it would have taken 13 hours to clear due to the limitations.
Even MS support advised us to use the Search-mailbox functionality as the replacement command was useless in this circumstance.
There is no viable replacement or solution for mass email clearing with the eDiscovery process. It is a poor solution.
