If removing your antivirus solves the problem, you should consider switching to a different antivirus solution. There are many great antivirus applications, but if you want maximum protection that won’t interfere with your system, you should then try BullGuard.
Solution 3 – Install the latest updates
If you’re getting Too many simultaneous connections error in Outlook, the problem might be the missing updates. To ensure that this issue doesn’t appear, it’s advised that you update Outlook to the latest version and check if that solves the problem.
In addition to Outlook, it’s important that you update Windows as well. By default, Windows 10 downloads the updates automatically, but you can also check for updates manually by doing the following:
- Use Windows Key + I shortcut to open the Settings app.
- In the Settings app, go to the Update & Security section.
- Now click Check for updates button.
Windows will now check for available updates and download them automatically in the background. Once you download the updates, restart your PC to install them. Once your system and Outlook are up to date, check if the problem is still there.
Solution 4 – Sign out from certain devices or applications
Too many simultaneous connections message can appear due to certain limitations in Gmail. In case you don’t know, you can have 15 simulations connections to your Gmail account, and if you exceed this limit, you’ll get the aforementioned error message.
It’s worth mentioning that certain applications can use two or more connections to access Gmail, so if you have several email clients or multiple devices connected to your Gmail account, it’s possible to quickly exceed this limit.
To fix this problem, it’s advised to sign out of certain email clients on your PC, phone or tablet. After you sign out on couple of clients, the problem should be resolved, and you’ll be able to access Gmail once again.
If you want, you can also sign out of all sessions. However, you’ll have to log back in again in every client manually. To sign out of all sessions in Gmail, do the following:
- Open Gmail in your browser.
- Scroll all the way down and locate Last account activity. Now click Details.
- A new window will now appear. You should be able to see all your current sessions. Click Sign out all other web sessions.
After doing that, you’ll be signed out from Gmail on all other devices and the issue should now be resolved. Keep in mind that you’ll need to sign back in manually on each email client, but that shouldn’t be a big problem.
Solution 5 – Check your password
Too many simultaneous connections Outlook error can occur if your password was changed or if it’s expired. This can be a problem, but you can fix it simply by resetting your password.
Once you reset your password you need to make changes in Outlook and change your login credentials accordingly. After doing that, the problem should be completely resolved and everything should start working again.
Solution 6 – Change Server Timeout value
Too many simultaneous connections error message can appear due to Server Timeout value, and in order to fix this issue, you need to make a couple of adjustments. Apparently, if Server Timeout value is too long, the client will try to make additional connections causing this error to occur.
However, you can fix the issue by doing the following:
- In Outlook open Account Settings.
- Go to the Advanced tab and lower the Server Timeout value.
- After doing that, click OK to save changes.
After making these changes, check if the problem is still there.
