用户的Outlook启动后就定住了，整个窗口界面被冻结起来无法进行任何操作，于是尝试修复identity未果，提示无法修复，这样的话唯有新建一个identity。按住option键，然后点outlook，直到弹出建identity的窗口后松手，点加号，给个名字新建一个，然后点下方齿轮那个图标将这个新建的identity设为默认，重新启动outlook，恢复正常，但是这样保存在原来identity的本地邮件数据就不见了。可通过如下方式找回：
1. Upgrade to Service Pack 2 (SP2) 14.2.1 or later See this article for details.
2. Create a new blank SP2 Identity.
3. Quit Outlook.
(Some users have found that deleting the database file in the new Identity helped).
4. COPY these Data Records folders from the old Identity to the new blank Identity replacing the new folders. Do NOT replace the root Data Records folder. Only the sub-folders listed here.
* Contacts
* Events
* Folders (one user reported replace Categories (not folders) worked better)
* Mail Accounts
* Message Attachments
* Message Sources
* Messages
* Note
* Signatures
* Signature Attachments
5. Select to rebuild the Identity in Database Utility.
6. Open Outlook and your data should be back.
