As part of the Patch Tuesday goodness, Microsoft is releasing .NET Framework 4.7. As has always been the case, .NET updates can break things customers (and Microsoft) weren’t expecting.
Microsoft is aware of at least one glaring issue for the update and the Exchange team is warning customers NOT to install it.
In .NET Framework 4.7 and Exchange Server, Microsoft provides its support statement. Essentially…
At this time, .NET Framework 4.7 is not supported by Exchange Server. Please resist installing it on any of your systems after its release to Windows Update.
However, the company is sure that some customers will have seen the message too late and is providing guidance on what to do if the update was already installed, which is the basic steps for safely removing the update, repairing the old version, and then blocking 4.7 from installing again.
