We have just begun a large program that has a requirement for project portfolio management. We initially attempted to upgrade our SharePoint and Project Servers to version 2019, but our sole reseller, SHI, has not responded to inquiries, so we have been forced to re-install our existing MOSS and MOPS 2013 servers in a new environment as a last ditch effort to get our system off the ground.
Unfortunately, once both (MOSS and MOPS) are patched with the January, 2022 cumulative updates (CU) and MS Project Professional 2013 is upgraded to SP1, it is no longer possible to create Enterprise Calendars. It is, furthermore, not possible to enable the option for local calendars, as this feature is no longer functional with the latest CU -- in other words, it is not possible to publish projects to Project Server without specifying an Enterprise Calendar. It ignores the local calendar setting. So we are stuck.
The feature to create a new Enterprise Calender via the Project Web App is also dysfunctional, as it attempts to open Project Professional 2013, but because of changes from the latest CU, it can no longer recognize MS Project 2013 properly.
So before we move with our backup option, Primavera, and shift a multi-million dollar project completely off Microsoft products, I wanted to ask the community if they know specifically which CUs and Office patches are compatible. I have seen this error all over the internet, and Microsoft does not have an answer for it. I am aware that 2013 has reached the end of its life, but we have no other options, since our reseller is not willing to work with us, and we are not technically permitted to buy direct.
TLDR; -- the latest CU for MOSS and MOPS render Project Server completely inoperable if there is a need publish projects with custom calendars.
