Troubleshoot sync and offline use
Resolve stale account data, provider refresh delays, failed offline saves, pending changes, and sync conflicts.
A recent change does not appear on another device
Likely causes
The first device has not finished saving, the other device has not pulled recent account changes, or sync is disabled on one device.
What to do
Confirm the first device shows a successful save. On mobile, pull down on Home or open Sync, confirm Cloud sync for this device is on, and choose an offered action such as Sync now or Refresh visible data. Repeat on the other device.
What not to do
Do not edit both copies repeatedly while their versions differ; that can create a conflict.
Provider Events have not refreshed
Likely causes
Harmonise account sync and provider updates are separate. The external calendar may have Sync turned off, be delayed, or be in an error state. A hidden calendar with synchronization enabled continues to update.
What to do
Open calendar Settings, confirm the account is connected and its calendar has Sync enabled, then choose Sync now on the account card. Use Refresh calendars only when the calendar list or access changed.
A save failed while disconnected
Likely causes
Some Event and Task actions require a connection to save and are not guaranteed to queue for later upload.
What to do
Restore the connection, reopen the item, confirm whether the change was saved, and repeat the action once if it was not.
What not to do
Do not assume an erroring save will upload automatically later.
A conflict needs review
Likely causes
A conflict was detected, but the current mobile app may not provide a version-choice action for it.
What to do
Open Sync and choose Fetch latest conflict status when it is available. Avoid further edits to the same item until its current state is clear. Contact support if the app does not provide a resolution action.
Refresh cannot complete
Likely causes
The device is offline, the signed-in account changed, or the service rejected the refresh.
What to do
Confirm the connection and account, read the visible error, and use Try syncing again, Retry checking this device, or Retry once. If cached data is still visible, treat it as older information until refresh succeeds.
