Hi, Alex Hammer1
Good day!
Thank you for posting to Microsoft Community. We are glad to assist you!
According to your description, I'm sorry to hear you're having trouble with your Outlook calendar sync on your Android devices.
First of all, before we troubleshoot this issue, would you please allow us to collect some detailed information as below:
- Are you using a Microsoft 365 business account(@xxx.onmicrosoft.com/@yourdomain.com) or a personal account (ending in outlook.com/hotmail.com/live.com/msn.com) or another third-party POP/IMAP account?
If you're using an Office 365 for business account(exchange), would you please try following steps and see if it can make any differences:
- Check Account Type:
- Ensure your email account is set up as an Exchange account, not IMAP or POP. Go to Settings > Accounts > Exchange and tap your email address. If it's listed as IMAP or POP, remove the account and re-add it as an Exchange account.
- Enable Calendar Sync:
- Go to Settings > Accounts > Exchange and make sure the "Sync Calendar" option is enabled. If it's grayed out, it might be due to the account type or permissions.
- Reset Account:
- In the Outlook app, go to Settings, tap the account that is not syncing, and select Reset Account. This can help refresh the connection.
- Re-add Account:
- If resetting the account doesn't work, try removing and re-adding your account. Go to Settings > Accounts, select the account, and tap Delete Account. Then re-add your account and ensure it's set up as an Exchange account.
- Check Permissions:
- Ensure Outlook has the necessary permissions to access your calendar. Go to Settings > Apps > Outlook and make sure Contacts and Calendar are enabled.
- Update App and Device:
- Make sure both your Outlook app and your device's operating system are up to date. Sometimes, updates can resolve syncing issues.
- Reinstall the App:
- If the calendar is still not syncing, try reinstalling the app and check if it fixes the issue.
