How to configure an Exchange maintenance account

Creating the impersonation role

To enable impersonation on Exchange Server for user LayerAdmin, launch PowerShell and issue the following command:

New-ManagementRoleAssignment -Name LayerImpersonationRole -Role ApplicationImpersonation -User LayerAdmin

Creating a new throttling policy

If a Layer throttling policy has not already been created, then create a new throttling policy that does not limit concurrent connections to the Microsoft Exchange Server:

For Microsoft Exchange 2010

New-ThrottlingPolicy LayerThrottlingPolicy -RCAMaxConcurrency $null -RCAPercentTimeInAD $null -RCAPercentTimeInCAS $null -RCAPercentTimeInMailboxRPC $null -EWSMaxConcurrency $null -EWSPercentTimeInAD $null -EWSPercentTimeInCAS $null -EWSPercentTimeInMailboxRPC $null -EWSMaxSubscriptions $null -EWSFastSearchTimeoutInSeconds $null -EWSFindCountLimit $null

For Microsoft Exchange 2010 SP1 - SP3

New-ThrottlingPolicy LayerThrottlingPolicy -RCAMaxConcurrency $null -RCAPercentTimeInAD $null -RCAPercentTimeInCAS $null -RCAPercentTimeInMailboxRPC $null -EWSMaxConcurrency $null -EWSPercentTimeInAD $null -EWSPercentTimeInCAS $null -EWSPercentTimeInMailboxRPC $null -EWSMaxSubscriptions $null -EWSFastSearchTimeoutInSeconds $null -EWSFindCountLimit $null -CPAMaxConcurrency $NULL -CPAPercentTimeInCAS $NULL -CPAPercentTimeInMailboxRPC $NULL

For Microsoft Exchange 2013

New-ThrottlingPolicy LayerThrottlingPolicy -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited

To apply this policy to LayerAdmin:

Set-Mailbox "LayerAdmin" -ThrottlingPolicy LayerThrottlingPolicy

Amending an existing throttling policy

For Microsoft Exchange 2010

Set-ThrottlingPolicy LayerThrottlingPolicy -RCAMaxConcurrency $null -RCAPercentTimeInAD $null -RCAPercentTimeInCAS $null -RCAPercentTimeInMailboxRPC $null -EWSMaxConcurrency $null -EWSPercentTimeInAD $null -EWSPercentTimeInCAS $null -EWSPercentTimeInMailboxRPC $null -EWSMaxSubscriptions $null -EWSFastSearchTimeoutInSeconds $null -EWSFindCountLimit $null

For Microsoft Exchange 2010 SP1 - SP3

Set-ThrottlingPolicy LayerThrottlingPolicy -RCAMaxConcurrency $null -RCAPercentTimeInAD $null -RCAPercentTimeInCAS $null -RCAPercentTimeInMailboxRPC $null -EWSMaxConcurrency $null -EWSPercentTimeInAD $null -EWSPercentTimeInCAS $null -EWSPercentTimeInMailboxRPC $null -EWSMaxSubscriptions $null -EWSFastSearchTimeoutInSeconds $null -EWSFindCountLimit $null-CPAMaxConcurrency $NULL -CPAPercentTimeInCAS $NULL -CPAPercentTimeInMailboxRPC $NULL

For Microsoft Exchange 2013

Set-ThrottlingPolicy LayerThrottlingPolicy -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited

To apply this policy:

Set-Mailbox "LayerAdmin" -ThrottlingPolicy LayerThrottlingPolicy 
Adding your secure Exchange Web Services (EWS) password in to The Layer
Log in to your account in The Layer and go to the mail agent section as below.
Then select EWS Impersonation account. 
Add username and password
As a guide we would recommend not using the following in your password:
  • Your company name
  • your own name
  • your address 
You should choose a random yet secure password which contains the following:
  • a minimum of 8 characters 
  • contains a mixture of both numbers and letters
  • at least one capital letter
  • at least 2 special characters
