Settings permissions for Exchange

Setting Exchange Permissions

Below you'll find a description on how to give a service account application impersonation permission within Exchange 2010/2013/Office365.

Note - please ensure  that you set the password for the Service account never to expire. If that isn't possible, then it is the responsibility of the customer to ensure that the password is always updated in Exchange and in Pronestor before it expires.

Please note: Setting of permissions on Exchange can have some latency before the permissions are set and available. Please allow up to 30 min. for Exchange to have the permissions committed.

    Setting Throttling Policy (NOT required per default)

    Use Exchange Management Shell
    Create new policy
    Ex. New-ThrottlingPolicy -Name nothrottlepolicy
    Set throttling on ews
    Ex. Set-ThrottlingPolicy nothrottlepolicy -ewsmaxconcurrency $null
    Set-ThrottlingPolicy nothrottlepolicy -ewsmaxsubscriptions $null
    Associate service account to policy 
    Ex. Set-ThrottlingPolicyAssociation -Identity -ThrottlingPolicy nothrottlepolicy
    An association can be listed and verified with:
    Ex. Get-ThrottlingPolicyAssociation

    It should show a throttlingpolicyid = nothrottle
