What’s wrong with Ventura’s Exchange Calendar sync and how to fix it is the subject of this tutorial. Many have criticized the newest OS from the Cupertino firm, saying it is one of the most bug-ridden versions of Apple’s operating system ever. Although we try to refute this claim, Ventura always manages to outdo us with its many bug fixes.

Ventura’s Exchange Calendar synchronization is a total nightmare.

Many users have complained that the calendars associated with their accounts aren’t behaving as intended in OS.

When it does sync, it does so with inaccurate information; for example, the Exchange calendar appointment is never displayed on a good day, and all birthday entries are displayed a day early.

But that’s not all; these are only a few problems. Apple Mail users have complained that their Exchange accounts frequently fail to receive new messages. Even its Invite function is behaving in an illogical way. There is no way to accept or decline an event manually; circumstances are occasionally taken without the user’s knowledge or consent. You may still be able to accept invitations after they’ve already been received.

Users have tried utilizing Fantastical with Outlook to avoid all these problems, but it hasn’t worked. It would appear that all services that rely on the syncing features of macOS are now flawed. Further, these flaws are exclusive to macOS Ventura; they do not exist in macOS Monterey.
