Hi,

My Exchange Server database copy has a status 'Dismounted' How do I re-mount that?

Thanks

Ian

mount-database <DB>  

using Exchange Powershell.

What about log queue lenght?

maybe cannot do that.
if your DB in DAG group has "content index state failed" its mean you cannot change active DB.

please run this command for update

Update-Mailboxdatabasecopy -identity "dabase/server" -CatalogOnly

and try to check status again.
