Released: March 2020 Quarterly Exchange Updates

Thanks for including file hashes for CU16 in KB4537678, but the filename has a typo cu15 "ExchangeServer2016-x64-cu15.iso" in the 2020-03-18 revision of the page.

http://support.microsoft.com/kb/981474 link it's broken.

I get an error when trying to upgrade to CU16.

Execution-policy set to untrestricted

It is during the setup of mailbox role:mail transport

The error is:

I have a question: if Unified Communications is no longer supported or included in Exchange 2019, why are Lync Server, Speech Platform, UC API and other related things still prerequisites?

All the downloads should now be available. Sorry for the delays.

DJP210 We're aware of this and it needs a little more time. Please be patient. The pack also includes the fr-CA language pack but it may also take a little more time. 

//EDIT:

UM packs are available right now.

UM language pack downloads page still returns a 404. When will that be addressed, and will the downloads include the fr-CA language pack? (With CU15, it was missing originally and took a few days for it and the rest of the missing ones to appear.)

Martin_Aigner - yes it does include that fix, and we're updating the KB's to reflect that. Thanks for the question. 

This update is not mentioning to include the fix for CVE-2020-0903, neither does the CVE cover an update for CU16.

What are your plans on this?

Thanks as always

Martin

mguerra81 yep, we‘re aware of this and responsible folks are working to get this fixed asap.
