我為何想要這樣做?Why would I want to do this?

在 Exchange Server 與 Exchange Online、 預設的探索信箱的大小上限為 50 GB。它用來儲存在就地 eDiscovery 搜尋結果。已變更的大小限制之前,組織可能增加為超過 50 GB 的存放區配額。因此,探索信箱無法成長超過 50 gb。有三個預設的探索信箱大於 50 GB 的問題:In Exchange Server and Exchange Online, the maximum size of the default discovery mailbox is 50 GB. It's used to store In-Place eDiscovery search results. Before the size limit was changed, organizations could increase the storage quota to more than 50 GB. As a result, discovery mailboxes could grow to more than 50 GB. There are three issues with a default discovery mailbox that is larger than 50 GB:

  • 不受支援。It's not supported.

  • 無法移轉至 Office 365。It can't be migrated to Office 365.

  • 如果是預設的探索信箱在 Exchange Server 2010 中,無法升級至 Exchange Server 2013 或更新版本。If it's the default discovery mailbox in Exchange Server 2010, it can't be upgraded to Exchange Server 2013 or later.

如何解決此問題取決於您是否要從超過 50 GB 的預設探索信箱中儲存搜尋結果。How you resolve this depends on whether you want to save the search results from a default discovery mailbox that's exceeded 50 GB.
