Reminders in Exchange 2010 SP1

Just stumbled upon an interessting issue in Exchange 2010.

Consider the following Scenario:

Exchange 2010 + Outlook 2010 or Outlook 2003 or Outlook 2007

Organizer creates a Meeting request, his calendar settings in Outlook look like this ( Default Reminders are turned OFF ):

Attendee also has the same Calendar Options configured in Outlook.

When the meeting request arrives at the attendee, we still have a reminder.

This should not be the case. If Organizer and Attendee don’t want to have a reminder, for whatever reason, they shouldn’t get one.

Apparently we had this issue also in Exchange 2007, it was fixed with SP1 Rollup Update 4.

https://support.microsoft.com/default.aspx?scid=kb;en-us;945854 - A meeting reminder is still active when you configure Outlook to send no reminders to an Exchange Server 2007 user

This was fixed in Exchange 2007 , however , we can also see this in Exchange 2010.

The solution in Exchange 2007 was this:

After you apply this update rollup, use Notepad to create a file that is named "StoreDriver.config" in the %EXCHINSTALLFOLDER% \bin folder. Make sure that the content of the StoreDriver.config file includes the following text.

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<storeDriver>

  <parameters>

   <add key="AlwaysSetReminderONAppointment" value="false" />

  </parameters>

</storeDriver>

</configuration>

Testing in my Exchange 2010 Environment showed that we can also can fix this issue using the same steps.

Creating the file described in the Article above, in the %EXCHINSTALLFOLDER% \bin folder on the HUB Servers fixed the issue. when Organizer sets reminder to NONE and Attendee has reminder to NONE, they won’t get a reminder.

This has to be done on all the HUB Transport Servers, Transport service needs to be restarted.
