Downtime Credit

Not legal advice. Not run by or linked to Microsoft or any vendor. Nothing you type leaves your browser. A credit is not cash.

An outage can mean a credit on your next bill.

Work out what your company may be owed, get the request written and keep track of the deadline; you send it.

You need four numbers: users on your plan, how many lost email, for how long, and what you paid for November.

Does this apply to us? Possibly, if your company pays for a Microsoft 365 business plan and users could not send or receive email in Outlook on the web. Bought through a reseller or your IT company? Pick that in the statement: your provider asks Microsoft for you. Open and Open Value licences get days of service instead. See who cannot claim.

Credit statement

Microsoft 365 email outage reported on 12 November 2026

Example numbers: Harbor & Pine Dental (made up).

everyone with an email account on the plan
the ones who could not send or receive email in Outlook on the web
How long they had no email
From your invoice: the fee for this service for November. Billed yearly? Use the part that covers November (about one twelfth); the agreement speaks of fees “applied to” the month.
Where did you buy Microsoft 365?

Your credit appears here.

A credit lowers a later bill. It is not cash. This is an estimate from your numbers and our reading of the agreement. The vendor decides.

How this was worked out
All email-minutes in November 30 days × 1,440 minutes × your users (the agreement calls these User Minutes)
Email-minutes lost each user without email × the minutes they were down (Downtime User Minutes)
Share of the month email worked to 4 decimals, never rounded up (the uptime)

Write it

Fill in what you know. Anything left out stays as a highlighted blank in the request, for you to complete before you send it.

Fields marked asked for are items the agreement lists; leave any blank and fill it in later in the letter.

Paste it into a support request to Microsoft. If someone else manages your Microsoft account, send it to them.

Send it before

One all-day event on the deadline, with reminders 14 days and 3 days before.

Sooner is safer. The agreement names no time zone, and the claim must arrive with all the information it asks for.

Who can claim, and what counts

Check these before you send: who the agreement leaves out, what it counts as down, and which fee to type.

Who cannot claim here

What counts as down

Microsoft counts a user as down only when they could not send or receive email in Outlook on the web (the browser version of Outlook). Count only those people and that time.

Groups of people

If some people were down longer than others, add a line for each group. Each group holds different people: count nobody twice.
