Getting "The simultaneous search limit has been exceeded." error when running more then 2 New-MailboxSearch commands via powershell.  I have raised the DiscoveryMaxConcurrency throttle to 10, but it still limits the maximum to 2 simultaneous.  What config am I missing?

Hi Tabuelt,

Base on my knowledge, in exchange 2013, there are only 2 searches can run simultaneously by default.

You can try to create an new throttling policy which has changed the default value of DiscoveryMaxConcurrency, 

and then assign it to the user with delegated Discovery Management permission.

Best regards,
