Microsoft currently reports Outlook.com as operational, so there is no published restoration time for today’s disruption; the public status feed was last updated November 12, 2026 at 19:31 UTC.^1^
Because sending, receiving, and Calendar are all unavailable, try these checks:
- Open Outlook.com in a private/incognito browser window. If it works there, the problem is likely confined to the original browser session.
- Check Settings → General → Storage. A full Microsoft cloud storage allocation prevents sending and receiving mail; messages received while storage is full are returned to their senders.^2^
- If Outlook.com displays storage as 0/0 GB or incorrectly says it is full, delete messages with attachments larger than 10 MB, then sign out and sign back in. Microsoft documents this as a workaround for a storage-reporting issue.^3^
- If Outlook.com still fails, select Help on its menu bar, enter the problem, and then choose Still need help? → Yes to contact Outlook.com support.^2^
If this is a Microsoft 365 work or school mailbox rather than Outlook.com, contact the organization’s Microsoft 365 administrator. Tenant-specific incidents may appear in the administrator’s Service Health dashboard even when the public consumer status shows operational.
