Hello, here are the screenshots of the process on a clean Windows system with a single Vivaldi window with activated e-mail functionality after pressing F2 and entering "mail":

I am asked for my login name and a password (for @outlook.de OAuth), then there is a login attempt - the window remains open - everything looks fine in the manual server settings - no e-mail account is created.

@stereissThese are the windows that appeared. I did this process, but nothing happened.
I'll try again later.
Thank you very much.

Fetch installer from vivaldi.com.
Try uninstall (do not let Uninstall remove browser profile data!) in your Windows Settings or Apps
Re-install with Vivaldi installer.

@DoctorG ...unfortunately did not work - same behaviour as before...

@stereiss Strange issue.

Only for a test if a fresh profile work:
Exit Vivaldi
Start Windows Explorer
Copy next line
%LOCALAPPDATA%\Vivaldi\
Paste into address field of Explorer
Hit Return
Rename folder User Data to User Data-Bak as a backup
Start Vivaldi
Go thru Welcome page
Add a mail account

Does this work?
If yes, something in your olf profile is broken.

@DoctorG Thanks for the tip - it helped!

Firstly, I renamed the "user data" directory for all my profiles in accordance with the tip. When I restarted Vivaldi, I was able to create an e-mail account.

Afterwards I cancelled the renaming and then just deleted the profile for e-mail and calender and created a new one - even then I was able to create email accounts again.

Thanks to everyone who gave me hints or tips - I really appreciate the support here!

[DoctorG]

@stereiss I am glad to have helped you.

@DoctorG it worked for me too. thanks.

[estudioepc]

@DoctorG Perfect, thanks!
Now, can you tell me how I can do that with GNU/Linux Kubuntu?
Is this the path I should back up?
/home/epc-ubuntu/.config/vivaldi/Default

[DoctorG]

@estudioepc I guess rename Default to Default-BAK
