I couldn't specifically say since my admin.microsoft.com fails pukes on a wildcard certificate for azureedge.net.

Also, multiple bankers I'm speaking to about Anthropic's IPO can't send or receive work e-mails. So that's a thing.

I just realized your name is the entire song / artist. Are you Jermaine Dupri?

"Office 364" is apparently a trending term.

The running joke in my last shop a few years ago was "Office 265"

(shameless self plug) the microsoft 362 extension[0]:

replaces all occurances of microsoft/office 365 with microsoft/office 362 (not in links, just in the visible text)

Microsoft Outofluck

We need to get beyond the arguments of 364 vs 365 and develop a new equilibrium in terms of availability that accounts for humans being equipped with these new found breaks as we spend time off of work.

Office 360 at one point in history.

We just don’t know how good we’ve got it, that’s all!

Thanks for the tip!

Do you have official reference for this?

There's two parts, the actual downtime and the SLA agreement...

At my day job, we have a calendar integration that polls Microsoft's Graph API across hundreds of Microsoft 365 tenants. We saw our first metric spike in 5xx errors at 2026/11/12 17:33 UTC. As of writing it's 2026/11/13 09:44 UTC and we are still encountering a full outage, so 16 hours and 11 minutes.

With a SLA calculator [1], assuming no other downtime this month and entering `16h 11m 0s`, we get: * Yearly SLA: 99.82% * Monthly SLA: 97.78%

I found an SLA document list here [2].

I downloaded Service Level Agreement for Microsoft Online Services (WW) English (2026/10/01). There's a heading for Exchange Online that says:

Uptime Percentage : Service Credit < 99.9% : 25% < 99% : 50% < 95% : 100%

Which seems to agree with what the original commenter said for this month.

[1] https://uptime.is/reverse [2] https://www.microsoft.com/licensing/docs/view/Service-Level-...

> Uptime Percentage : Service Credit > < 99.9% : 25% > < 99% : 50% > < 95% : 100%

These targets feel very very low nowadays.

99% uptime for email means 3.5 days/ year no email.

(although 99.9 = about 8 hours/year would seem bearable - but maybe not for a company like microsoft)

> 99% uptime for email means 3.5 days/ year no email

Depends on how it appears, if it was one or several large chunks that is much more disruptive than minutes per day. 3.5 days/year is equivalent to less than 15 minutes/day.

It sucks no matter how you slice it, but the severity/impact depends on more than the aggregate downtime.
