Troubleshooting issues in Vivaldi Webmail

Login issues

In case you can’t log in to your account, first make sure you’ve typed the username and password correctly.

If you’re having trouble remembering your username, send yourself a reminder here: https://login.vivaldi.net/profile/id/recoverAccount.

In case you’ve forgotten the login password, reset it here: https://login.vivaldi.net/profile/id/userInfoView.

If you try logging in with the wrong password at least 5 times, the account will get locked for 5 minutes as a security measure.

If login fails, you can also try whether login works to other Vivaldi services. For example, try logging in to your account’s profile on Vivaldi.net.

For our support team’s assistance, please send us a message at the end of this article and describe the issue in detail.

New account login issues

Vivaldi Webmail is a service for active Vivaldi Community members using Vivaldi’s services. This means that new users, who registered their account after 4th of May 2023, and users who registered between October 2019 and May 2023, but never verified their phone number, first need to build up a reputation to be granted access to the Webmail service.

The reputation system is replacing the previous requirement to verify an account via one’s phone, that was set up to limit the number of spam accounts. For additional information, read our blog post on the topic.

Locked account

The account can be locked for a few reasons:

  • You’ve tried logging in with the wrong password more than 5 times and the account got temporarily locked.
    In that case wait 5 minutes and try again, if you’re absolutely sure you have the correct password this time.
    In case you’ve forgotten the password, reset it here.
  • The account was locked for breaking Vivaldi’s Terms of Use.
    We have applied several measures and criteria to Vivaldi Webmail in order to prevent spam from being sent using our webmail service. We use automatic tools for spam prevention and if they detect spam, they can lock the account. This means that there occasionally may be some false positives.
    If your account was suddenly locked after using Vivaldi webmail, and you’re sure you haven’t broken our Terms of Use, please get in touch with us using the contact form at the end of the article. We’ll review the account and decide whether the account can be unlocked or not.

Webmail service is down

Occasionally, login won’t be possible, because the services are down. When downtime is needed due to scheduled maintenance work, we’ll notify everyone with a message sent to the account’s recovery email well ahead of time.

Sometimes accessing your mail won’t be possible, because something has suddenly stopped working. The team will do their best to solve these issues as soon as possible. In that case check Vivaldi’s Status page and keep an eye on the Webmail category on the Forum, where our team and volunteers will keep you updated with the latest news.


Issues with sending or receiving messages

Sending messages

In case you can’t send messages or recipients claim they don’t receive them, please get in touch with us using the contact form at the end of the article.

If the messages refuse to send, tell us what the error message says.

If the message was sent, but not delivered, please also include the message headers. To get the message headers in Vivaldi webmail:

  1. Go to the Sent folder;
  2. Open the email that wasn’t delivered;
  3. Below the recipient email address, click on Details > All headers;
  4. Copy the text in the pop up window to your message.

Receiving messages

In case you’re expecting an email from someone, but it isn’t delivered, please also get in touch with us using the contact form at the end of the article. In the message to our support team, in addition to your account information, please include the full email address and the date and time, you expected to receive the email.


Trouble with using Vivaldi Webmail in a mail client

In case you can’t access your mail in a mail client, double check the login settings (especially, if you’ve recently changed the password) and server settings in the mail client’s account settings. We’ve listed Vivaldi Webmail’s server settings for incoming and outgoing mail here.

Error messages explained

Sometimes things go wrong and instead of achieving your goal, an error message is shown. In this article, we’ve listed common error messages shown when using Vivaldi services doesn’t go according to plans and suggestions for solving the issue.

Browse through the list to find a solution to the error you’re seeing. In case you need our assistance, use the contact form at the end of this article.

Vivaldi.net

“Login failed! Please recheck the username and password and try again.”

This error is shown when the username or password haven’t been written correctly or the account doesn’t exist. For example, the account was deleted by the owner or due to inactivity.

Your account hasn’t been confirmed yet.
Please check your email for the confirmation link.
If you haven’t received it or it has been more than 48 hours since you registered, you can resend the code here.

Before logging in to your new Vivaldi account, it needs to be activated with a code in the email that was sent to the email address you gave as the recovery email in the registration form.

When you can’t see the email in your Inbox, check also the Spam folder. In case you can’t find the email or the link has expired request a new code.

If you activated the account, but still see this error, wait a few minutes and try logging in again.

If you made a typo in the email address or gave an invalid email, please send us a message using the contact form at the end of this article, so we can fix it for you.

“Login failed. It looks like you’ve forgotten the password.
Would you like to reset the password?”

In case the username is correct, but the password is not, then after the 4th failed login attempt you’ll get this error message, suggesting you to reset the password.

If you try logging in one more time and it also fails, the account will get locked for 5 minutes as a security measure.

“Your account has been temporarily locked as a result of multiple unsuccessful log in attempts. Please reset the password in 5 minutes.”

After the 5th failed login attempt the account gets locked for 5 minutes. You’ll need to wait out these few minutes, after which you can send yourself a password reset email.

“This account has been locked.”

Seeing this error means that the account was most likely locked for breaking Vivaldi’s Terms of Use.

Some blocking, for example due to misbehaviour on the Forum, is done manually by Forum admins and moderators. Other, such as spamming in Webmail, is mostly done automatically by our antispam filters.

If you believe the account was locked in error, please send us a message using the contact form at the end of this article.

“Can’t verify the user.
Something went wrong.
If this error keeps appearing, please contact us.”

We’ve confirmed that an extension called Dark Reader breaks functionality on Vivaldi.net’s account related pages, resulting in this error message being shown. If you use this extension or any others, please disable them temporarily (you might also have to restart the browser) and try again.

If you don’t use extensions or the error persists, please try the same action in a Private Window or Guest Profile to rule out other browser settings causing this issue. If that doesn’t help either, please send us a message using the contact form at the end of this article.


Webmail

Access denied. More info here.

In some mail clients the message is:

Your account does not have permission to access mail services.

Vivaldi Webmail is a service for active Vivaldi Community members using Vivaldi’s services. This means that new users, who registered their account after the 4th of May 2023, first need to build up a reputation to be granted access to the Webmail service.

Reputation is built by actively using other Vivaldi.net services – the Forum, Vivaldi Social, Blogs, Themes, and the browser’s Sync feature.

The reputation system is replacing the previous requirement to verify an account via one’s phone, which was set up to limit the number of spam accounts. For additional information, read our blog post on the topic.

Login failed

This error is shown when the username or password have been written wrong or the account doesn’t exist. For example, the user deleted the account or it was deleted due to inactivity.

Scan QR codes with Vivaldi on Android

QR (Quick Response) Codes are an easy way to share links and other information. With Vivaldi’s QR Code scanner on Android you can quickly scan QR Codes and barcodes to open links, menus, payment screens, apps and get specific information unique to the code without the need to type anything. In addition to scanning, you can also create codes to share links.

  1. Open the QR Code scanner using one of the methods mentioned above;
  2. On first use, grant Vivaldi access to your phone’s camera;
  3. Place the frame on the phone’s screen over the QR Code or barcode;

To create a QR code:

  1. Open the web page you want to share;
  2. Go to Vivaldi menu > Share;
  3. Select QR code;
  4. Show your phone to someone, so they could scan the code or download the QR code as an image.

To apply a Page Action to a web page:

  1. Go to the Vivaldi menu > Page Actions;
  2. Enable the option(s) you want to apply.

Use Mail, Calendar and Feeds in a separate user profile

If you’d like to use Vivaldi Mail, Calendar and Feeds separately from your main browser, we suggest setting your mail and calendar accounts up in a new User Profile. Alternatively, you can also install a second Vivaldi as a Standalone version.

Add a new Profile

  1. Click on the Profile button in the top right corner of the browser window and select Manage People.
    Profile button on the Address Bar
    Alternatively, go to Settings > Address Bar > Profile Management and click on Manage People.
  2. Click on Add Person at the bottom of the popout menu.
  3. Pick a name for the new profile, select or upload an avatar and decide whether you want a Desktop shortcut for the profile or not.
  4. Click on Add Person.

Once you’ve created the new profile, you can always open it from Vivaldi’s profile menu. You can also open the second profile from the desktop shortcut, if you created one. On Windows, while the second profile is open, you can also pin the profile button to the taskbar.


Set up your accounts

To use Vivaldi Calendar, make sure you’ve enabled Mail, Calendar and Feeds from Settings > General > Productivity Features. On a brand new installation or in a new User Profile, choose the “Fully Loaded” option in the welcome flow.

Go to Settings > Mail and Settings > Calendar to set up your accounts. For detailed instructions have a look at the following help pages:


Open links in a different profile

To open links from your Mail profile in your main browser profile:

Option 1

  1. Make sure the other profile is open;
  2. Right-click on the link in the Mail profile;
  3. Select Open link as (profile name).

Option 2

  1. Have two windows open in a way that both are visible;
  2. Hover the mouse cursor over the link;
  3. Click and start dragging the mouse cursor downwards;
  4. While dragging, move the link to the second window, for example, to the Address Field, over the Open a new tab button or to a text field.
  5. Release the mouse button to place the link.

Copy content from one profile to another

Unfortunately, it’s not possible to highlight text on a web page and use Send by Mail and Save as Calendar Event features across profiles.

But, in addition to the classic Copy and Paste option, there is another way to move content from one profile to another.

  1. Have two windows open in a way that both are visible;
  2. Hover the mouse cursor over highlighted text, link or image;
  3. Click and start dragging. ;
  4. While dragging, move the content to the second window, for example, to the email composer or calendar description.

Custom taskbar icon

On Windows, each profile gets it’s own Task Bar icon when open. To differentiate the main browser profile from the Mail, Calendar and Feeds profile, you can assign a custom icon for the Task Bar button. To do that:

  1. Open the second profile;
  2. Right-click on the taskbar button and select Pin to taskbar;
  3. Right-click on the taskbar button again;
  4. Right-click on Vivaldi (above Unpin from taskbar) and select Properties;
  5. In the Shortcut tab, click on Change icon;
  6. Browse for your custom icon (has to be in an Icon file (.ico)) and click Open;
  7. Click Ok first in the Change Icon dialog and a second time in the Properties dialog.

Unfortunately, macOS and Linux don’t support separate profile buttons on their dock/taskbar.
