How to Sync Outlook with Webmail?

Microsoft Outlook is a potent email and personal data management tool that supports many email accounts. Multiple benefits come from using Outlook to manage your webmail accounts. Unlike standalone webmail accounts, Outlook offers a broader range of tools for managing private data. In this article, I will let you know how to sync Outlook with webmail.

So, let's get started!

Part 1: What's the Difference Between Outlook Client and Outlook Web App?

The Outlook Web App (OWA) is your official UW-Platteville email and calendaring account. All campus account holders will have access to the Outlook Web app via a browser from anywhere they have an internet connection. Outlook Web App provides basic email, calendar, contact, and task functionality.

OWA also provides access to OneDrive (storage) and Word, Excel, and PowerPoint Online. Mobile devices can connect to your Office 365 account directly or via the OWA app. The majority of account holders will use Outlook Web App.

However, The Outlook Desktop Client must be installed and linked to your Office 365 account on your computer or laptop. Only the machine on which it is installed has access to the desktop client. If you manage other people's email accounts and calendars, the Outlook Desktop Client benefits you.

Part 3: Tips to Prevent Outlook Sync Issues

Now you know how to sync Outlook with webmail. But it would help if you took some necessary actions to avoid Outlook sync issues. In this part, I will help you by explaining tips to prevent Outlook sync issues. So, let's find the tips here:

#Tip 1: Turn off Cache Exchange Mode

If you use Outlook to access an Office 365 or Exchange Server-based email account, you can turn off Cached Exchange Mode to stop Outlook sync issues.

To do so, follow the below-mentioned steps:

Step 1: Go to File>Account Settings> Account Settings.

Step 2: Click Change after selecting your Office 365 or Exchange email account from the list.

Step 3: Uncheck the Cached Exchange Mode box under Offline Settings.

Step 5: Tap on the Finish button. Then, restart Outlook.

#Tip 2: Change the Check Frequency

Stopping synchronization is not always necessary. Assume Outlook is stuck on synchronizing the inbox. This could happen if the system checks for new mail too frequently. The freeze is caused by auto checks that overlap. Adjust the interval for synchronizing inbox to avoid a backlog of send/receive tasks. If you manage multiple accounts, 15 minutes is the ideal amount of time to avoid hanging.

Alternatively, prioritize accounts so that the most important ones are checked first. Use the sending/receiving button to customize the mail setup. It can be found on the Mail Setup tab via Tools Options in 2007 and earlier versions. In later versions, including Outlook 2013, the button is located in the 'Advanced' section of Options, which can be accessed through File.

#Tip 3: Swap out the subscribed folders

You will sync more slowly the more folders you have. Open Outlook and modify the choice if you want to change the IMAP folder settings. You can do this by following the steps described below:

Step 1: Right-click on the mail folder to access the contents.

Step 2: Select IMAP folders and click subscriptions in the newly opened dialog box.
