OneDrive Personal Vault cannot unlock, error code 0x8004db90

I have done the same via the Web interface, and I have also directed the OneDrive support team to this community forum entry to see others having the same issue. Here is the response I received:

Hello there,

We wish you a great day.

Perhaps the more users that report the same issue directly to them, the more priority it will receive - one can only hope.

Dear Microsoft,

I hope that someone will read this message.

Several individuals, including myself, have suffered as a direct result of these actions, and the evidence gathered shows that these damages are widespread and systematic. In the absence of immediate corrective actions on your part, I am prepared to initiate a collective action (class action).

Hi, nobody from Microsoft will read your message.

Here is just a forum were we help each other.

A class action will not work because Microsoft can call their terms, where the item 6 (Service Availability) is saying:

We strive to keep the Services up and running; however, they are not offered with a guaranteed level of quality of service and all online services suffer occasional disruptions and outages. In the event of an outage or disruption to the Service, you may temporarily not be able to retrieve Your Content. We recommend that you regularly backup Your Content and Data that you store on the Services or store using Third-Party Apps and Services.

The only way is contacting the support and ask for a solution ASAP.

Right-click on your OneDrive icon (on the system tray, next to the clock, on Windows PC) --> Click on the gears on the top right-hand corner --> "Get Help" --> On the window that will pop-up, click on Contact Support (at the bottom of the window).

I absolutely agree with every single word. The less whom you would expect to have such issues is Microsoft. And seeing that they dont absolutely care about it, and dont correct the problem for more than one month is ridiculous. The answer like "we know the problem and we are doing our best to solve it, but cannot tell the exact time"... is out of this world. I mean more than a month they are not solving the problem. Maybe in MS they don`t understand that people save very important documents oin their vault.

I still do not have access to my vault. How funny that you pay for a service supposedly for availability and integrity and you can't get availability and who knows if you also have integrity with this problem.

Indeed , still not solved.
