Microsoft Outlook is a powerful tool for managing email, calendars, tasks, and more. But sometimes, you might see a message saying Outlook cannot connect to the server. Whether you are using Outlook 365, Office 365, or the Outlook desktop app, this problem can stop your emails and interrupt your day.
Many users face issues like Outlook trying to connect, Outlook not connecting to server, or Outlook email not connecting to server, even when the internet is working fine. If you are seeing errors like Outlook won’t connect to server, Outlook is not connecting to server, or Outlook keeps saying trying to connect, don’t worry. You are not alone—and this guide will help you fix the problem.
When Outlook shows this error, it means that your email client is unable to reach the mail server. In simple terms, Outlook is trying to get in touch with the place where your emails are stored, but something is blocking that connection. It could be a problem with your internet, a wrong setting, or a server that is down.
This problem can happen in any version of Outlook, whether you are using it on Windows, Mac, or even the mobile app. It can also affect all types of email accounts, including Gmail, Yahoo, Outlook dot com, Exchange, or business email.
Understanding why Outlook cannot connect to the server can help you fix the issue faster. Here are some of the most common reasons:
If your device is not connected to the internet or if your connection is unstable, Outlook will not be able to connect to the email server.
If your email settings such as server address, port number, or username are wrong, Outlook cannot reach the server.
Outlook has an offline mode. If it is turned on, Outlook will stop connecting to the server until you switch it back online.
Sometimes, security software can block Outlook from accessing the internet or the email server.
If your Outlook profile is damaged, it may stop working correctly and fail to connect to the server.
Sometimes, the email server is temporarily down due to maintenance or other issues. In that case, Outlook cannot connect until the server is back online.
If you are seeing messages like Outlook cannot connect, Outlook will not connect, or Outlook having trouble connecting to server, try the steps below.
Even if it looks like your internet is working, Outlook may not be connected.
Open a website like Google
If it does not load, restart your router
If Outlook still won’t connect, try switching to a different network
If your internet is working, move to the next step.
Sometimes, just restarting the program can fix the issue.
Close Outlook completely
Wait for a few seconds
Open it again
Check if the problem is solved.
Sometimes, Outlook gets stuck offline, and users report Outlook trying to connect to server or Outlook keeps saying trying to connect.
Open Outlook
Go to the Send or Receive tab
If you see Work Offline is selected, click it to turn it off
You will know it is online when Work Offline is not highlighted.
Incorrect account settings can lead to errors like Outlook won’t connect to exchange, cannot connect to server Outlook, or Microsoft Office cannot connect to the server.
Go to File > Account Settings > Account Settings
Select your email account and click Change
Check if the incoming and outgoing server names are correct
Also check the port numbers and security types
If you are not sure about the correct settings, contact your email provider or check their website.
If your Outlook profile is corrupted, you may see errors like Outlook desktop not connecting to server, or Outlook app not connecting to server.
Go to Control Panel
Click Mail
Choose Show Profiles
Select your profile and click Repair
Follow the prompts to finish the repair.
Security software can sometimes block Outlook. To check this:
Temporarily turn off your antivirus and firewall
Open Outlook and see if it connects
If it works, you may need to allow Outlook through your firewall or add it to your antivirus exceptions list.
If repairing did not work, create a new profile.
Go to Control Panel > Mail
Click Show Profiles > Add
Give the profile a name and set up your email account again
Choose Prompt for a profile to be used and select the new one when starting Outlook
This can fix deep errors in the current profile.

Click Update Now
Also, make sure your Windows system is up to date.
Many small problems can be solved with a restart.

If none of the above steps work, the problem may be on the server side.
