Archive Exchange Store Manager reports below error in *.wlog files of some mailboxes.
"ERROR: Properties of deleted message are not accessible; message will be ignored."
As per AM v. 4.1.2 Quest_ArchiveManager_4.1.2_ReleaseNotesAddendum
The ESM service has been modified to handle an MS Exchange limitation that made it unable to fetch the properties of certain "soft-deleted" items.
The ESM recognizes that the message cannot be exported, reports the error once and does not continue to retry the message. These soft-deleted messages cannot be archived or retained by Archive Manager for future processing.
Note that they may have been successfully archived before being soft-deleted.
The behavior is by design.
