Outlook 2013 Contacting the Server for Information: Fix Stuck Sync Errors in 3 Clicks

Outlook 2013 getting stuck while contacting the server for information is one of those headaches that turns your inbox into a black hole. ⚡ I’ve seen this freeze up everything from home offices to small business networks, and the fix usually starts with something simple—like checking the server settings that Outlook refuses to update.

The problem almost always boils down to one of three things: corrupted profile data, misconfigured server settings, or a firewall blocking the connection.

I’ve repaired profiles that were stuck in this loop by resetting the account settings in under 3 minutes, but sometimes it takes digging into the server’s authentication requirements. The key is testing each layer systematically—network, Outlook config, and server response—without guessing.

You’ll walk away with a working sync, whether it’s a quick IMAP/SMTP refresh or a full profile repair. The worst-case scenario still takes less than 15 minutes if you follow the right steps.

I’ll show you exactly where to look first, so you don’t waste time on dead ends like rebooting or reinstalling.

This works for Outlook 2013 on Windows 7, 8, and 10, and covers the most common error codes like 0x8004010F and 0x800CCC0F. Let’s get it resolved—no tech degree required.

Why it happens

When Outlook 2013 gets stuck "contacting the server for information," it’s usually because something is blocking or slowing down the communication between your app and the email server. Below are the most common culprits—broken down with clear explanations so you can pinpoint the issue fast.

🔍 1. Server Overload or Downtime

If Microsoft’s Exchange or your company’s email server is overloaded, experiencing high traffic, or undergoing maintenance, Outlook will repeatedly attempt to reconnect, triggering the "contacting the server" loop. This is a server-side issue, meaning your computer isn’t the problem—it’s the infrastructure handling your emails.

🔹 Why it happens: Servers have processing limits. During peak hours (like 9 AM or 5 PM), too many users accessing the server at once can cause delays or timeouts. Even a single corrupted database or misconfigured rule on the server can trigger repeated sync attempts.

💡 Actionable check: Visit your company’s IT portal or Microsoft’s Service Health Dashboard to see if there are known outages. If the server is fine, the issue likely lies elsewhere.

🔒 2. Network or Firewall Interference

Your firewall, antivirus, or even your router could be blocking or throttling Outlook’s connection to the server. Some security software treats Outlook’s background sync as a "suspicious" process, interrupting the handshake required to fetch emails.

🔹 Why it happens: Firewalls use port rules to control traffic. Outlook typically uses ports 443 (HTTPS) or 6004 (Exchange ActiveSync). If these ports are restricted—or if your network has deep packet inspection enabled—Outlook may fail to establish a stable connection, forcing it to retry repeatedly.

💡 Actionable check:

• Temporarily disable your firewall/antivirus to test if it’s the issue.
• Check your router’s port forwarding settings to ensure Outlook’s required ports are open.
• If on a corporate network, ask IT about split tunneling or VPN restrictions.

🔄 3. Corrupted Outlook Profile or Cache

Outlook stores a local copy of your emails, calendar, and settings in a profile and Offline Folder File (OST). If this cache gets corrupted—or if your profile settings are misconfigured—Outlook may struggle to sync properly, leading to endless retry loops.

🔹 Why it happens: Corruption can occur from:

• Abrupt shutdowns (e.g., power loss, forced restart).
• Manual deletions of the OST file without proper cleanup.
• Conflicting add-ins or outdated Outlook updates.
• A damaged Outlook Data File (.pst) or Exchange mailbox.

The OST file acts as a buffer, but if it’s damaged, Outlook may keep trying to reconcile differences with the server, never succeeding.

💡 Actionable check:

• Press Windows + R, type %localappdata%\Microsoft\Outlook, and delete the OST file (Outlook will recreate it on next launch).
• Create a new Outlook profile via Control Panel > Mail > Show Profiles.
• Run the Microsoft Support and Recovery Assistant for Outlook.

⏳ 4. Slow or Unstable Internet Connection

Even a laggy Wi-Fi signal or high latency can make Outlook’s sync process time out. If packets of data are dropping or taking too long to reach the server, Outlook will retry, creating the "stuck" illusion.

🔹 Why it happens: Outlook expects a response within a few seconds during sync. If your ping to the server exceeds 200ms (common with weak signals or ISP throttling), the connection times out. This is especially true for:

• Public Wi-Fi networks (hotels, airports).
• Mobile hotspots with weak signal.
• ISPs that throttle bandwidth-heavy apps.

💡 Actionable check:

• Test your connection speed with Speedtest.net. Aim for 10+ Mbps download for smooth syncing.
• Switch to a wired Ethernet connection if possible.
• Restart your router or move closer to the signal source.
• Use a VPN (if allowed) to bypass ISP restrictions.

📦 5. Exchange Server Configuration Errors

If your organization uses Exchange Server, misconfigurations like autodiscover issues, certificate errors, or outdated server protocols can break Outlook’s ability to sync. This is common in hybrid environments (e.g., mixing on-premises Exchange with Office 365).

🔹 Why it happens: Outlook relies on Autodiscover to automatically configure server settings. If:

• The Autodiscover service is misconfigured (e.g., wrong DNS records).
• The server’s SSL/TLS certificate is expired or invalid.
• Outdated Exchange Web Services (EWS) protocols are in use.
• Your mailbox is on an old Exchange version (e.g., 2010 vs. 2019).

💡 Actionable check:

• Ask IT to run Test-OutlookConnectivity in PowerShell (Exchange admin tool).
• Manually configure server settings in Outlook:
  1. Go to File > Account Settings > Account Settings.
  2. Select your email account > Change.
  3. Under More Settings > Connection, ensure Connect to Microsoft Exchange using HTTP is checked.
  4. Click Exchange Proxy Settings and verify the server URL (e.g., outlook.office365.com).
• Update Outlook to the latest version (2013 is outdated—consider upgrading).

How to solve it

When Outlook 2013 gets stuck "contacting the server for information," it’s usually a sign of a hiccup in the sync process. The good news? Most issues can be resolved with a few targeted steps. Below, we’ve mapped common causes to their fixes—plus prevention tips to keep your emails flowing smoothly.

###

🔥 Server Connection Problems

If Outlook is struggling to reach your email server (Exchange, Office 365, or IMAP), try these steps:

• 🔄 Restart Outlook and Your Router Close Outlook completely, then restart your computer and router. A fresh connection often resolves temporary glitches.
