Regarding .NET Framework 4.6.1 and Exchange compatibility

Hi everyone,

As many of you should know the .NET Framework 4.6.1 has been sent to Windows Update as a recommended update. However there are some issues with Exchange, such as Mailboxes getting quarantined and databases failing over unexpectedly in Exchange Server 2013, described in and so we ask you to refrain from updating for the time being.

I urge you to read all the details at :

On .NET Framework 4.6.1 and Exchange compatibility – Exchange Team Blog – Site Home – TechNet Blogs

For now you can prevent the deploy of the mentioned update by applying the steps described in .

Have a great day.
