Yandex business mail has dropped to view-only mode

Organizations that keep their own domain on Yandex 360 see a "view only" warning when they open the mailbox. This is not an outage. Free business mail has ended, and an account without a topped-up balance cannot process new mail.

What changed?

According to Yandex's own announcement, the free version of Yandex 360 for Business is gone as of 8 December 2025. The migration is staged. Each organization receives an email 7 days before the first payment. If no plan is chosen in that time, the service stays in view-only mode.

Personal @yandex.com mailboxes are not on this plan. What is affected are organizations that attached their own domain to Yandex 360. Even if the MX record is correct, sending does not open without payment.

What happens in view-only mode?

Old messages remain readable on the web. The organization's data is not treated as deleted. Yandex says everything returns to normal after payment.

New data cannot be added, however. The on-screen warning says mail cannot be used in the web version, the app, or third-party programs such as Outlook. Replying, forwarding, and working from a client stop.

On day 1 of an unpaid balance the service moves to restricted mode, and from day 8 to view-only. Nonprofits and charities are exempt from this change. They can keep using it for free.

Disk is separate and harsher

On Yandex Disk the timeline is shorter. From day 1 without payment the quota drops to 5 GB. If the limit is exceeded, Disk also goes view-only immediately. On day 45 Disk is fully blocked. On day 91 the files are deleted and do not come back even if you pay later. While you are waiting on the mail, download the files on Disk separately.

What should you do?

1. In the organization panel, check the balance and the active plan under Finance. The warning asks the administrator to top up the balance.
2. Download a copy of the critical mailboxes before access stops. Do not change the MX record before the old messages have been moved to the new server. Otherwise new mail lands in one place and the archive in another.
3. If there are work files on Yandex Disk, copy them to a computer in the meantime. Do not wait for day 91.
4. If payment cannot be completed from Turkey, do not stay on the same screen for days. Yandex does not clearly say whether incoming mail is still accepted. The decision is either to pay for a plan or to move the mail to another platform.

Do not assume the work continues just because the mailbox is still there. Mail that cannot send is not mail.
