Today’s #MicrosoftCloudQuickFix is that Exchange Server 2013 is reaching end of support in a little over 7 months from now. After April 11, 2023, #Microsoft will now longer provide technical support for problems that may occur, bug fixes for new issues that are discovered, security fixes for vulnerabilities that are discovered, and time zone updates.
Upgrade to Exchange Server 2019 – See the following page on Microsoft Docs for Exchange Server system requirements and/or
Migrate to Exchange Online – See Decide on a migration path in Exchange Online on Microsoft Docs
In either case I highly recommend using the Exchange Deployment Assistant which is a web-based tool that asks you about your current Exchange environment and generates a custom step-by-step checklist that will help you.
Note: It is a supported coexistence scenario for Exchange 2019 and Exchange 2013 provided all your Exchange 2013 servers in your organization are patched to Exchange Server Cumulative Update 21 (CU21 – released June 2018) or higher. See Exchange Server build numbers and release dates
