Frequently Asked Questions

Why is my Office 365 calendar not updating automatically?

This issue is often caused by temporary network disruptions, outdated login credentials, or stalled synchronization settings within the 'Access work or school' menu on your device.

Will clearing my browser cache delete my Exchange calendar events?

No, clearing your browser cache and cookies only removes temporary website data stored locally on your device. Your actual calendar events remain safely stored on the Exchange server.

How do I check if my Exchange account is properly connected to Office 365?

You can verify the connection by going to Settings > Accounts > Access work or school on your Windows device, where properly connected accounts will be listed with an 'Info' option.
