As a reminder, Vyte can only synchronize with an ICS calendar in read-only mode.
To synchronize your Office 365 calendar to your Vyte account:
Go to your Vyte settings
Go to your calendar settings
Click on "Add a calendar account Pro”
Click on "Read only ICS calendar Pro"
Enter the URL of your ICS calendar
Your ICS calendar is now synchronized with your Vyte account
Check the "Show as busy" box for each sub-calendar in your connected calendar whose events should be marked as unavailable on Vyte (Learn more about the "Show as busy" and "Display to me" options)
Don't forget to save your changes 😉
