Yesterday We put two databases of the server 2. Now we can create an exchange archiving task on the server 2. But the problem is that we can't enable mailboxes. It fails atfer a long time. So For your explanation I will create 2 system maiboxes one for each server.
and I will execute these commands in exchange management shell:
SetEVExchangePermissions.ps1 -user example\ev_vsa
SetEVThrottlingPolicy.ps1 -user example\ev_vsa
On the server 1
Add-ADPermission -Identity EVSysMbx1 -User ev_vsa -AccessRights ExtendedRight -ExtendedRights “Send As”
On the server 2
Add-ADPermission -Identity EVSysMbx2 -User
ev_vsa -AccessRights ExtendedRight -ExtendedRights “Send As”
