Problem

While trying to synchronize a new device with an Exchange mailbox, you receive an error with your new mobile phone partnership.

The Exchange Server 2010 Default Throttling Policy is configured to accept 10 ActiveSync devices per mailbox only.

You can validate this setting by using EMS

Get-ThrottlingPolicy def* | Select Name,EASMaxDevices

Solution

Use a scheduled PowerShell script to delete old ActiveSync Device partnerships that have not been used for a defined period of time.

Script

Find the most recent version on TechNet Gallery and Github, following the links provided in the Links section.

Modifiy the script path variables to fit your requirements. The variables are configured in the ### BEGIN Variables section.

Steps being executed:

  1. Fetch all user mailboxes
  2. Iterate through each user mailbox and determines the number of ActiveSync devices and the number of devices which have not synchronized since 150 days
  3. Delete ActiveSync device registration, if a user has more than 4 devices in total and a minimum of 1 device that have not synced within 150 days

ENow Management System 7.0ENow has released version 7.0 of the ENow Management System (EMS).

Besides a major face lift of the OneView Dashboard new functionality has been added to the successful monitoring and reporting solution:

  • New look to the One-look Dashboard
    Complete redesign of our interface background and menu options. New colors and styles with the same One-Look functionality
     
  • New ENow Admin Console
    The new cutting edge look afforded to our EAC makes navigation a breeze, with the intuitive buttons and easy to read options configuring the product has never been easier.
     
  • DAG Enhancements for Exchange 2013
    Added a new DAG Status indicator to the Namespace page for one stop monitoring of all DAG Servers, the user no longer has to drill under functionality of each PAM to see their status. The new indicator now shows all DAG Statuses under a single page for quick access.
     
  • Remote Installation of New Agents
    With the addition of the new ENow Remote Installer the user never has to leave the web server to install new agents. The user can now use this new GUI interface to select servers and roles and automatically push out new agent installs.
     
  • New Enhanced Log file Collector
    If you have an issue or general question and the Support team needs your log files, no more going to each server compressing the files and then emailing them to the team. This new GUI interface allows you to remotely grab the requested log files and automatically upload them to our FTP server for you.
     
  • Revamp of whole Mailscape 365 Product Layout
    With the addition of so many new and enhanced Mailscape 365 features we had to redo the whole layout of the indicators for an easier to navigate look and feel. It gives the admin the ability to troubleshoot that much quicker by correlating test show under specific indicators that show any breakdown in the tenant systematically.
     
  • Remote Office 365 enhanced testing
    We have changed our remote monitoring to be more robust and mimic the normal tenant monitoring. This service allows the Admin to not only test his tenant from within the network, but also utilize our Azure server to test the tenant remotely.
     
  • Added Lync Online DNS monitoring
    As part of our push into the cloud we are starting our Uniscope 356 monitoring with a simple Lync Online DNS test. Just configure the Domains you wish to test the DNS records of and we will verify the DNS records that are vital to your team.
     
  • New Mailscape 365 reports
    We have added more admin related reports to allow the customer a more in-depth look into their tenant and the users they are administering.

Sometimes you have the same scheduled task configured for manual execution available across different servers. Instead of triggering the start manually on each server by logging on remotely, you can trigger the scheduled task on each server by using Remote PowerShell.

The following example triggers the configured scheduled task My-Manual-Task on server MYSERVER01 to MYSERVER06.

$cimSession = New-CimSession -ComputerName MYSERVER01,MYSERVER02,MYSERVER03,MYSERVER04,MYSERVER05,MYSERVER06

Start-ScheduledTask My-Manual-Task -CimSession $cimSession

Remove-CimSession $cimSession

Enjoy Remote PowerShell
