Hi,

the default DB which install with MB rule by default i want to remove it at all

i moved all the mailboxes but when i run the command of

get-mailboxstatistics -database default
m getting this result
[PS] C:\Windows\system32>get-mailboxstatistics -database aexsrv2db

DisplayName               ItemCount    StorageLimitStatus                                                 LastLogonTime
-----------               ---------    ------------------                                                 -------------
Microsoft Exchange App... 5        NoChecking
Nagwa                          2092         NoChecking                                          8/10/2012 7:08:49 PM
Microsoft Exchange        3                    NoChecking
Microsoft Exchange App... 3                    BelowLimit
SystemMailbox{54c02565... 18                   NoChecking

Mail box of Nagwa , one hundred percent am sure i moved to another DB and when i run the command on the other DB it give me Nagwa in the list with nearest lastlogontime

so why Nagwa listed in the default ?

is it safe to remove the DB now ??? why there are system mailbox listed ?

Get-Mailbox Nagwa -Database Aexsrv2DB | Remove-Mailbox

I would say for other mailboxes move them just in case they are used for some App

Get-Mailbox -Database Aexsrv2DB | Move-Mailbox -TargetDatabase ****

don't be too sure, if it i showing in Aexsrv2DB  then either the move failed or it is still in move. running

Get-Mailbox Nagwa | fl *database*

will return the current db of that user.

also open you RMC -> reciepient config ->> move requests and check the status of Nagwa  is it failed ? if it is then delete the move request and move it again but, this time, add the bad item limits a bit.

Also the default db has the arbitration mailboxes you can see them by running
get-mailbox -database aexsrv2db -arbitration

move them also by running
get-mailbox -database aexsrv2db -arbitration | new-moverequest -targetdatabase DBName

it doesn't change anything to your course of work

run

get-mailbox -database aexsrv2db
should return empty

and then
get-mailbox -database aexsrv2db -arbitration
it should also return empty

if that is the case then just delete the DB from exchange first and then you can delete the edb and log files

doesn't matter at all, once you can delete the DB in exchange you no longer need the folder

I would say move it and ensure everything works fine for a day if so then good to remove .... not sure if some last good backup is needed
