SYNCDATE DocsSync is active but events are not showing
What to check when a sync looks healthy but an event has no copy: direction, filters, how far ahead, then one Re-sync.
Last updated
A status of Active or Up to date tells you what SYNCDATE knows about its latest run. It does not prove that one particular event has a copy. Work through the checks below with a single missing event, in this order. Please do not delete the original, delete other copies or recreate the sync while you check, because that removes the trail that shows where the copy stopped.
1. Find the original and the expected copy
Open the event where it was created and note the account and calendar it is on, the account and calendar where you expect the copy, its start and end time with the time zone, and whether it is an invitation, a recurring event or an edited occurrence.
Then open the sync and check the calendar route. Names like "Calendar" or "Work" repeat across accounts, so check the account as well as the name.
Open the destination provider's web calendar and make sure that exact calendar is visible. If the copy is there but missing in Outlook desktop, Apple Calendar or a phone app, the provider has it and the delay is in that app. Refresh the app. If the copy is missing in the web calendar too, keep going.
Copies do not relay through a second sync. If A syncs with B and B separately syncs with C, a copy that arrived in B from A is not sent on to C.
2. Check the direction
A Push sends events only from its source side to its target side. A Mirror sends originals both ways. The arrows on the sync page show which calendar is the source for the event you picked.
If a Mirror works from one calendar but not the other, check the failing direction on its own: the original event on that side, that account's access, the filters and the activity. See Direction: one-way or two-way or Mirror or Push.
3. Check whether the event is eligible
Compare the missing event with each rule under Which events copy in the sync's settings:
- Invitations uses your response to a meeting. A declined meeting can be left out while an event you own still copies.
- Working hours can exclude a day or a time. If only the first event of each day appears, write down the missing event's time zone and exact start and end rather than changing several rules at once.
- All-day, free-event, title and special-event rules can exclude an event that looks ordinary.
- How far ahead limits future single events. Past events is a separate choice made when the sync is first created. See Why events further ahead aren't copied.
Filters: which events get copied explains each rule.
4. Read the last run
Open the sync's activity and use Changes, Issues and All. Find the run after the event was created or changed, expand the row and read its result or error. For a create or update that succeeded, choose Check it landed. It asks the provider for the event again and only reads. Then confirm in the provider's web calendar.
If Last synced has not moved for days, the event has no activity row, or Check it landed says "Couldn't check just now", keep that evidence for support. A failed check can mean a missing event, an access problem or a provider-read problem.
5. Use Re-sync once
After you fix a calendar choice, a filter, the window or an account permission, open the sync menu and choose Re-sync once. It reapplies the current settings and catches missed events. Wait for the run to finish and read its activity before deciding. Repeating Re-sync without reading the result hides what happened.
6. Check account access
Open Accounts and check both the original and destination accounts. The destination must allow writes, and a shared Outlook calendar needs the access its owner or administrator gave. If Microsoft shows Need admin approval, Approval required or an AADSTS code, send your IT team the workspace admin page with the full message. See also Your work account needs admin approval. If an account asks to be reconnected, use the repair on its account card, then check that a later run succeeded.
7. Contact support with details
Use support in the signed-in dashboard, or the Support page if you cannot sign in. Include the sync page URL, the original and expected calendars, one event's start, end and time zone and whether it is owned, invited or recurring, the Last synced time, and the run ID and exact error from Technical details. Never send an app password, OAuth token or calendar feed URL. Redact guest names, meeting links and private titles from screenshots.
Frequently asked questions
Why can I see both calendars in SYNCDATE but not in each calendar app?
The combined SYNCDATE calendar reads your connected calendars into one view. It does not mean the sync wrote copies into each provider. Check the sync route and activity, then open the destination calendar in the provider's web app.
Why does a two-way sync work in only one direction?
Confirm the sync is a Mirror and that the missing event is an original on the failing side, not a copy from another sync. Then check that account's access, the shared filters and the activity for that direction. Adding one short test event you own on each side shows which direction fails.
Why does only the first event of each day copy?
Compare the events with Working hours, days, all-day and exclusion settings, and write down their time zones and exact boundaries. If equally eligible events get different results after a completed run, send the examples to support. A wider plan will not fix this.
Why are old recurring meetings missing, or why is one occurrence different?
Separate three cases: the whole series is missing, only old history is missing, or one edited or cancelled occurrence is wrong. Check the original series, the occurrence, the Past events choice made when the sync was created, and the activity. Send examples to support rather than deleting and rebuilding the series.
Why does a declined meeting still have a copy?
Confirm your response at the original provider and the Invitations setting, then read the first run after the response changed. Please do not change the copy's response. Send the original event and the run details to support.
What if I deleted the copied event myself?
A copy you deleted is a different case from a copy that never arrived. The Re-sync dialog may offer an option to restore copies you deleted. Choose it only if you want them recreated.
None of these checks needs an upgrade, and a bug in recurring events or provider writes should be reported as a bug, not treated as a plan limit.
