# monday.com Board Sync Troubleshooting: Column Names, Case Sensitivity, Bulk Syncing, and Unlinking

> The four issues behind most "my monday.com boards stopped syncing" reports: column name/case mismatches, label limits, bulk-sync rate limits, and permissions — with fixes for each.

## The short answer

After years of supporting board syncing at scale, nearly every "boards stopped syncing" report traces to one of five causes, in this order: **(1) column names/types don't match exactly, (2) a status column can't accept a new label, (3) permissions on a private board, (4) rate limits during bulk operations, (5) a webhook got removed.** Work the list top to bottom — each has a fast check.

## 1. Column names must match — exactly, including case

Columns sync when the **name and type match** on both boards. "Due Date" and "Due date" are different columns; a Status column won't sync into a Text column. The fastest check is [column mapping](/features/column-mapping) — it shows exactly which columns will sync and creates missing ones in one click.

## 2. The status column won't accept a new label

The classic *silent* blocker: the destination board's status column is at its label limit or restricted, so the incoming value can't be written — and the failure cascades into what looks like "one-way sync" or "boards won't connect." Check whether the destination status column can accept the source's labels (add one manually as a test).

## 3. Permissions and private boards

Automations act as the user who authorized them. If that user can't access the destination board (private board, revoked access, changed role), item creation fails — sometimes loudly (["no permission to duplicate pulses"](/troubleshooting/permissions-error)), sometimes quietly. Verify the authorizing user is a member of every destination board.

## 4. Bulk syncing and rate limits

Sharing hundreds of existing items at once runs into monday.com API rate limits. Use [batch actions](/features/batch-actions) in moderate batches (10–15 items) rather than one huge push, and let a batch finish before the next. For very large boards (thousands of items), stagger by group or status.

## 5. Webhooks were removed

Syncing rides on board webhooks. If an admin cleans up webhooks or a board is duplicated from a template, sync events stop arriving. See [why SIMB adds webhooks and how to restore them](/troubleshooting/webhooks).

## Keeping quota healthy: unlink what's done

Shared-item quota is spent on *active* connections. Set an automation to **unlink items when they reach a final status** — the item stays on its home board, the cross-board link is freed. (Prefer manual unlinking when only some closed items should disconnect.)

## Still stuck?

The [Discrepancy Report](/features/discrepancy-report) shows exactly which items and columns disagree across boards — start there, then contact support from the app with the item link. Support is measured in fewest-messages-to-resolution, so include the board and item in the first message.
