What If Mac Outlook Data Files Get Corrupt?

Moreover, it requires technical expertise from a normal user who just uses the mail programs for the accessibility of data. There is no need to deal with file formats and experience difficulty in doing so. Hence, it is recommended that users must be sure of the damaged database when rebuilding their identity. In such a case, users can follow up with two things explained in the section below.

  • If an Identity opens, users should attempt to export data and move into a new Identity rather than rebuild the identity.
  • If the message ‘Your database was rebuilt successfully’ is received on rebuilding the identity then apparently no problems exist. Still, it is suggested to export data into a new Identity. The reason behind this is to be sure about a corruption-free Identity.

Note – If rebuilding and restoring do not succeed, create a new identity to get back all over again. However, if rebuilding gets successful, then the entire Mac Outlook data can be exported into the PST file so as to be usable in Windows Outlook.
