How to Fix Slow Outlook Synchronization for Microsoft 365 Accounts
Product
Microsoft Outlook
Device & OS
not provided
Scenario
Syncing a recently migrated GoDaddy email account to Microsoft 365 within the Outlook desktop client.
Observed behavior
Outlook takes several minutes to synchronize emails and folders instead of updating immediately upon receiving new messages.
Before you start

Ensure that your Outlook application is updated to the latest version and verify your internet connection stability before modifying your account settings.

Solution 1Recommended

Verify and Change Account Type to Microsoft Exchange

Ensure your newly migrated Microsoft 365 account is set up as an Exchange account rather than IMAP, as Exchange synchronizes instantly.

When migrating a GoDaddy account to Microsoft 365, Outlook may incorrectly configure the new connection using the IMAP protocol. IMAP syncs on a scheduled interval (often several minutes), whereas Microsoft Exchange pushes messages to your inbox immediately.

1
Open Account Settings

Launch Microsoft Outlook. Click on 'File' in the top-left corner, select 'Account Settings', and then click 'Account Settings' again from the dropdown menu.

2
Check the Current Account Type

In the Email tab, locate your Microsoft 365 email address. Look at the 'Type' column next to it. It should say 'Microsoft Exchange'.

3
Re-add the Account if Necessary

If the type is listed as 'IMAP/SMTP', you will need to remove the account and add it again. Click 'New...', enter your email address, and let Outlook automatically configure it as an Exchange account using your Microsoft 365 credentials.

Verify and Change Account Type to Microsoft Exchange
Data Backup Recommendation: Removing an IMAP account removes the local cache. Ensure any folders labeled 'This computer only' are backed up before removing the account.

Frequently Asked Questions

Why did Outlook configure my Microsoft 365 account as IMAP instead of Exchange?

When migrating from older platforms like GoDaddy's Workspace Email, Outlook's AutoDiscover feature might retrieve outdated DNS records and configure the account using IMAP. Re-adding the account after the domain's DNS is fully updated to Microsoft 365 usually forces the correct Exchange setup.

Will deleting the SRS file delete my emails or contacts?

No. The SRS (Send/Receive Settings) file only contains the rules and schedules for how Outlook connects to the server to check for new messages. Deleting it will not affect your emails, calendars, or contact data.

How long should a Microsoft Exchange account take to sync in Outlook?

Unlike IMAP, which checks for mail on a timed schedule, Microsoft Exchange uses push technology. This means new emails should appear in your inbox almost instantaneously as they arrive on the server.
