9. Now perform restore-mailbox

 

  1. Paste the Mailbox GUID  into Notepad. For example,f911a4c2-42de-42c1-8d97-abef7766063c.

    Note The GUID contains five sections that are separated by hyphens.

  2. On a blank line in Notepad, type the characters from the first section of the GUID (for example,f911a4c2), in two-character portions separated by backslash character, in reversed order. For example: \c2\a4\11\f9.

    Note You must include the initial backslash character.

  3. Type the characters from the second section of the GUID (for example, 42de) in two-character portions separated by backslash characters, in reverse order. For example: \de\42.

  4. Type the characters from the third section of the GUID (for example, 42c1) in two-character portions separated by backslash characters, in reverse order. For example: \c1\42.

  5. Type the characters from the fourth section of the GUID (for example, 8d97) in two-character portions separated by backslash characters. For example: \8d\97.

    Note For this section of the GUID, you do not reverse the order of the two-character sections.

  6. Type the characters from the fifth section of the GUID (for example, abef7766063c) in two-character portions separated by backslash characters. For example: \ab\ef\77\66\06\3c.

    Note For this section of the GUID, you do not reverse the order of the two-character sections.

  7. Add each of the re-typed GUID sections together to form the msExchMailbox value. For example:
    \c2\a4\11\f9\de\42\c1\42\8d\97\ab\ef\77\66\06\3c

  8. On a new line in Notepad, use this new msExchMailbox value to create a msExchMailboxGUID entry similar to the following:
    (msExchMailboxGUID=\c2\a4\11\f9\de\42\c1\42\8d\97\ab\ef\77\66\06\3c)

    Note Include the parentheses in the preceding command.
