Error Messages Explained

A reference of the error messages you may run into across OneCal, what each one means, and how to fix it.

Calendar sync errors

"Item Not Found"

A sync shows the Error status because one or more of its calendars no longer exist at the calendar provider, for example because the calendar was deleted or the account changed. If the calendar still exists, fix it like this:

  1. Delete all syncs associated with this calendar.
  2. Remove the calendar in question from OneCal.
  3. Connect the same calendar again.
  4. Re-create the sync.

See Manage Your Syncs and Rename, Recolor and Remove Calendars.

"Calendar Pair Already in Sync"

You selected a calendar pair that is already synced, in the same direction, by another sync. Proceeding can create multiple clones for the same source event. Change the selection, or delete the other sync first. See the callout on the Calendar Sync intro.

Calendar connection errors

"Connection not complete"

A permission checkbox was not selected during the Google or Microsoft consent screen. Reconnect the account and select all permissions. See I Can't Connect My Calendar.

"This account has already been used in a free trial"

The calendar account was already used in another free trial. Contact our support team if you need it moved.

"This account is already registered by a different user"

The calendar account is connected to another OneCal user. Remove it there first, or contact us.

"Invalid Apple email or app-specific password"

Use an app-specific password created for OneCal, not your Apple account password. See Create an Apple ID app-specific password.

"Read-only calendars cannot be selected as targets"

You have view-only access to this calendar, so OneCal cannot create events on it. Read-only calendars can be used as sources, to read availability, but not as targets of a sync or as the booking calendar.

"This calendar is being used in one or more sync configs / booking links / your booking page"

You are trying to remove a calendar that another part of OneCal depends on. Update or delete the syncs, booking links or booking page that use it first. See Rename, Recolor and Remove Calendars.

Booking errors

The link was deleted, its URL changed, or all booking links were disabled because the workspace's trial or subscription expired. See Schedulers Can't Book Time With You.

"This time slot is no longer available"

The slot was taken or became unavailable between the moment the page loaded and the moment the scheduler confirmed. The scheduler can simply pick another time.

Private links can have an expiry date or a maximum number of uses. Generate a new private link and share it again. See Private Booking Links.

Sign-in errors

The magic link was already used or expired. Request a new one. See I Can't Sign In.

"Too many sign-in attempts"

Too many sign-in requests in a short time. Wait a few minutes and use the most recent email.

The email already has an account with a different sign-in method. Sign in with the original method, then add more methods from Settings. See Login Methods.

If you hit an error that is not listed here, contact our support team with a screenshot and what you were doing when it appeared.
