exchangesyncd process RAM leak - sync process with Microsoft 365, Office, Exchange Very much the same issue as others reported in this Apple Community Forum. exchangesyncd process is continuously increasing the use of RAM, up to 50GB RAM added per 24hrs. The problem started a few weeks ago. My configuration: MacBook 2021 M1 Pro chip with the latest OSX Ventura with the latest patches (version 13.4.1c). As per suggestions by others, killing the process didn't solve the issue. The process is automatically started again after each kill. Removing Microsoft Exchange account from my Mac, did solve the issue! Configuring the Exchange account again (after a Mac restart) all seem to work again (enabled all to sync: mail, contacts, calendar, notes, tasks) until the system tried to sync the calendar. While at first new calendar entries in the Calendar App of my Mac did sync with Exchange in the cloud and my other Apple devices, at some point various Mac calendar processes started to continuously use high CPU load (up to 100% of a single M1 core) and the exchangesyncd process started to eat a lot of RAM, again. From this point onwards no new calendar events synced between my Mac and Exchange in the cloud anymore. Disabling just the calendar sync in Exchange account settings on my Mac, brought everything back to normal. The problem seems to be with Calendar sync only. Disabling calendar sync in the Mac Internet Account section seems to solve the problem. Though this introduces a new problem: No Calendar information on Mac anymore. Workaround: Use the web-based Calendar App of Exchange/Outlook until a solution is provided. Hopefully, Apple solves this issue quickly!
