Exchange powerShell with administrator

I new to powerShell and exchange 2010. I'm trying to run powerShell as Admin using run as but PowerShell always say on the top Machine: servername instead of Administrator: servername.

I try to use following cmd to get all the mailbox with quote but receive no result.
Get-Mailbox -ResultSize unlimited | Where{($_.UseDatabaseQuotaDefaults -eq $false)}

what do need to receive Administrative privileges in Exchange power-shell.
Thanks

This has nothing to do with running elevated.

Do you get any results when running:
Get-Mailbox -ResultSize unlimited | Where{$_.UseDatabaseQuotaDefaults -eq $false} 

Open in new window


Or
Get-Mailbox -ResultSize unlimited

Open in new window

OK, are you a member of any of the Exchange administration groups? How many mailboxes do you expect?

Are there any other Exchange administrators? If so, ask them to give you permissions for what you're trying to do. If you are the only admin, then add you admin account the Organization Management group in Active Directory. (requires you to log off and then on to get an updated token)

Sounds like there might be an issue with the Exchange server then.

Can you run the Exchange BPA and look through the event log for issues?

i just check the logged files and its giving error code event id 6 "Couldn't find database "MN-PFDB0xxx"

This is public folder database. I don't know why its defaulted to my public folder instead of searching my DAG DB.

Are you getting an error at the command prompt or is this in the event log?

If it's in the event log then that probably has nothing to do with the EMS issue. The Get-Mailbox command is actually getting a lot of its info from AD and not the DB(es) directly.

Have you run the BPA yet?

Are you able to query other mailboxes besides your own? e.g. Get-Mailbox user1

Issues resolved. I asked my coworker who has exchange right to run the query and it works for him. He was a part of group called "rExchangeAdministrator".

I added my useracc with this group and I can able to run the cmd. I don't think this is a default group. I believe someone set this group to handout permissions.

Thank you guys for your help
