Possible Causes:

3. Device-Specific Settings: Incorrect email settings on devices (such as smartphones or email clients) can result in sync issues.
4. Large Attachments: Emails with large attachments can take longer to sync, impacting overall email performance.

Resolution Steps:

Step 1: Check Network Connectivity

1. Ensure you have a stable and fast internet connection. A slow or unreliable connection can lead to email sync issues.

Step 2: Check Server Status

1. Verify if there are any ongoing issues or outages with Microsoft's email servers: a. Visit the Microsoft 365 Service Status page Link. b. Check for any reported email-related problems.

Step 3: Verify Email Settings

1. Double-check your email client or device settings, including incoming and outgoing server addresses, port numbers, and authentication methods.

Step 4: Clear Email Cache

1. If using an email client or app, try clearing the cache: a. Access the settings or preferences of your email client. b. Look for an option to clear cache or temporary data. c. Restart the email client after clearing the cache.

Step 5: Remove and Re-add Email Account

1. Sometimes, removing and re-adding your email account can resolve sync issues: a. Remove the email account from your email client or device settings. b. Restart the device. c. Re-add the email account with the correct settings.

Step 6: Check Email Size and Attachments

1. Avoid sending or receiving emails with large attachments, as they can impact sync performance. Consider using file-sharing services for large files.

Step 7: Contact Support

1. If the problem persists, reach out to your organization's IT support or Microsoft support for further assistance.
