Position:

2. Query which mailbox database the user is in, purpose: Quickly locate the user in the mailbox database.

Get-mailbox-database "Mailbox Database 1***9" | Export-csv C:\Mailbox-1XXX9-2018-05-01-1345.csv

Export Mailbox-1xxx9-2018-05-01-1345.csv can query whether a user is in a database.

Note the query sAMAccountName to determine.

3. Repairing the database

A. Query mailbox Database status.

ESEUTIL/MH "H:\Program files\microsoft\exchange server\v15\mailbox\mailbox Database 1***9

\mailbox Database 1***9.edb "

State:dirty Shutdown //Database status is not normal, so users can not use the mailbox properly.

"H:\Program files\microsoft\exchange server\v15\mailbox\mailbox Database 1***9\"

5. Mount the mailbox database, the status is loaded, and the test user is sending and receiving messages properly.

The test found that some users could use the mailbox, and some users could not use the mailbox.
