为何需要执行此操作?Why would I want to do this?

在 Exchange Server 2013 和 Exchange Online,默认发现邮箱的最大大小为 50 GB。它用于存储在就地电子数据展示搜索结果。已更改的大小限制之前,组织可能会增加到超过 50 GB 的存储配额。因此,发现邮箱无法增加到超过 50 GB。有三个问题大于 50 GB 的默认发现邮箱:In Exchange Server 2013 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:

  • 不受支持。It's not supported.

  • 无法迁移到 Office 365。It can't be migrated to Office 365.

  • Exchange Server 2010 中的默认发现邮箱时,它无法升级到 Exchange Server 2013。If it's the default discovery mailbox in Exchange Server 2010, it can't be upgraded to Exchange Server 2013.

如何解决这取决于是否要保存超过 50 GB 的默认发现邮箱的搜索结果。How you resolve this depends on whether you want to save the search results from a default discovery mailbox that's exceeded 50 GB.
