A large number of mailbox items per folder may impact the Exchange mailbox performance. You may notice a drop in performance while performing certain actions when there are a lot of mail items in an email folder, such as Inbox, Sent Items, etc. Further, a folder may fail to display correctly or take longer and lead to synchronization errors.
