How long do we have to wait?

There is no published waiting period: Outlook.com is currently listed as operational, so a loading screen that persists across all access methods should be reported to Outlook.com Support rather than treated as an active system-wide outage.^1^

Try the documented loading workaround

For Outlook.com in a web browser:

1. Open it using the latest version of Microsoft Edge, Chrome, Firefox, or Safari 16 or later.
2. Temporarily disable AdBlock, uBlock, and other advert or pop-up blockers for Outlook.com.
3. Refresh Outlook.com. Microsoft documents these extensions as a cause of messages loading slowly, timing out, or not loading at all.^2^
4. If the loading screen remains, test in a supported browser with no extensions enabled. Older or unsupported browsers can also have loading problems.^3^

Escalate if it fails everywhere

Because the failure occurs across all the access methods you tested, submit an account-specific support request:

• If Outlook.com opens far enough, select Help, enter the problem, then scroll to Still need help? and select Yes.
• If you cannot sign in or the Help interface will not load, use Microsoft’s dedicated Outlook.com sign-in support form.^4^

Include the approximate start time, affected browsers/devices, and that the account remains on the loading screen across every client. Only Microsoft Support can inspect an account-specific service or mailbox problem and provide an applicable recovery time.
