Frequently Asked Questions

Why does Microsoft Whiteboard become slow after adding PDFs?

Importing large or complex PDFs can consume significant system memory and rendering resources, causing the app to lag. Updating to the latest version helps optimize memory usage during these tasks.

Will I permanently lose my drawings if the pen lines disappear?

In most cases, disappearing lines are caused by a synchronization delay rather than permanent data loss. Forcing the app to sync by refreshing the board or checking your internet connection often restores the strokes.

Are there other ways to fix syncing issues across multiple accounts?

If issues persist across multiple devices and accounts, try logging out of your Microsoft account within the app, restarting your device, and logging back in to refresh your connection to the cloud servers.
