Does OST (Outlook cache mode) also include all emails in "Recover deleted items" folder? I have a few users who are under litigation hold for many years so there is no deletion by Exchange retention policy. Users have been manually cleaning up emails from each folder then clean up Deleted items. Or shift+delete. The "Recover deleted items" folder contains large amount of emails. I checked their mailbox properties under EMC. They are over 50 GB. I know we have extended their recover deleted items folder before (> default 20 GB). They want to change from Outlook online mode to cache mode. But I'm afraid that it could exceed the 50 GB limit, if it includes the recover deleted items folder. Can someone confirm if OST contains it?
Thanks in advance.
