When trying to add or update my Outlook contacts information I get this error message: lpe-data.errorSaveFailed

I sent a message to Microsoft yesterday with the issues but I haven't heard anything to date, One of the subscribers was told that Microsoft was working on the problems. We'll see !!!!!!!!!!!!!!!

yes can you fix it

Me too with a Japanese Win11 on both Chrome and Edge
Oddly I can edit and add from my iPhone 12 using Chrome (not the OL app)

Happening to Japanese users too. They are referencing your thread in theirs, so just to keep things mutual

   Actually if you follow the link and click on "I have the same problem" on the Japanese page, we might get better user servise from the Japanese User support. The location is the same, next to the "Reply" button at the top and it reads   

"わたしも同じ問題をもっています。"
Currently only 3 in Japan but lets pump it up. We the people will be heard by MS in every language.

German, French, Chinese? Any one got any other languages of MS User Support we can click "I have the same problem" on?

I'm getting the same error message (8-29-22, 4:20PM Pacific) when trying to add a new contact.
lpe-data.errorSaveFailed

August 29, same issue as above for the past few days until current. Just weighing in to add to the list, hoping for an update/fix soon. If helpful for anyone else, when I add a contact to my phone directly, it is synchronizing with Outlook contacts properly. The error appears only when trying to update online via the browser.
