IMPORTANT: Incase above steps are missed for Onlyoffice installation, following is the manual steps for installation.

As root user run below commands: (assuming Zimbra is already installed)

$ wget -O /opt/zimbra/bin/zmonlyofficeinstall https://raw.githubusercontent.com/Zimbra/zm-core-utils/10.0.9/src/bin/zmonlyofficeinstall
$ chmod 755 /opt/zimbra/bin/zmonlyofficeinstall
$ /opt/zimbra/bin/zmonlyofficeinstall

IMPORTANT: Zimbra OpenSSL with default FIPS Configuration

Please be advised that, TLS 1.2 is the minimum supported version if FIPS is being used with OpenSSL 3.0. We recommend using Zimbra with strong TLS configuration for increased security. Please follow instructions in Cipher-suites-wiki to set correct ciphers as per current versions of openssl, nginx and postfix.
From this patch going forward Zimbra OpenSSL will be configured to work with FIPS compliance enabled by default. You do not need to take any action, unless you run into issues, you can switch to the non-FIPS provider as follows:

Run below commands to Enable/Disable FIPS providers on all servers.

Disable FIPS provider:

As root user run below commands

Take backup of openssl.cnf
cd /opt/zimbra/common/etc/ssl
cp openssl.cnf <backup-path>/openssl.cnf

Copy openssl-source.cnf file
cd /opt/zimbra/common/etc/ssl
cp openssl-source.cnf openssl.cnf

Verify that, FIPS provider is disabled:
Run below command and verify fips provider is not listed
/opt/zimbra/common/bin/openssl list --providers

As zimbra user run below commands
su - zimbra
zmcontrol restart

Enable FIPS provider:

As root user run below commands

Take backup of openssl.cnf
cd /opt/zimbra/common/etc/ssl
cp openssl.cnf <backup-path>/openssl.cnf

Copy openssl-fips.cnf file
cd /opt/zimbra/common/etc/ssl
cp openssl-fips.cnf openssl.cnf

Verify that, FIPS provider is enabled:
