Cumulative Update Repository

To help those who manage Exchange On-Premises, I wanted to create a repository for CU and UR updates for various versions of Exchange. This project had moved forward much slower than I wanted to and am now at around 95% done uploading CUs for Exchange 2013 and 2016 as well as 100% done for Exchange 2010 SP1/SP2/SP3 URs. If you are looking for any Exchange 2019 downloads, they will never be posted here. These are only available via the Microsoft Volume Licensing Center. Please do not ask for a copy as I cannot provide it.
To download old CUs and URs, please refer to the below links:
Exchange 2016 Cumulative Updates (95%)
Exchange 2013 Cumulative Updates (100%)
Exchange 2010 (100%)

** NOTE **
For those who are running Exchange 2019, please note that the Volume License Center does not appear to hold the previous versions of Exchange 2019. Only the current CU appears to be listed. Right now the RTM version is not listed on the site. As there is no public trial or download of the RTM version of Exchange 2019, there is no ability to compare versions. We should be able to confirm if this is the future when CU2 comes out. If it does, this will confirm an even more drastic version of Exchange update availability than has previously been known. With 2013 and 2016, there were usually 3 versions available for download (Current CU and then the teo previous CUs). Now we only have one available version.
