Microsoft 365 business continuity: Keep email and meetings running the next time Outlook goes down
A standby Google Workspace, set up and tested before you need it. When Microsoft 365 stops working, your mail switches over and your team keeps going in Gmail, Meet and Docs. You keep Microsoft 365 for every other day.
12 November 2026: Outlook, Teams and OneDrive went down
Outlook stopped sending and receiving mail for business and personal users, first in the Americas and then in other regions. Microsoft said Teams, SharePoint, Copilot and Defender XDR were affected too, and later blamed a large number of servers being unexpectedly unavailable. For many teams, the problems lasted for hours. The time to prepare for the next one is before it starts.

What is business continuity for Microsoft 365?
It's a second place to work, ready before an outage starts. With Google Workspace for Business Continuity, your key people have Google accounts waiting in the background. When Microsoft 365 goes down, you route email to Google and they sign in. It isn't a migration and it isn't a backup: Microsoft 365 stays your main system, and the standby keeps people working while it's down.
Where your mail goes, on any day
The same setup on three kinds of day. Only the route changes.
Every day
Microsoft 365 as usual
Mail, meetings and files run on Microsoft 365. The Google Workspace standby waits in the background, with accounts set up and tested.
Outage day
Switch to the standby
When Outlook or Teams stops working, your admin points mail routing to Google. Your team signs in to Gmail, Meet and Docs and keeps going.
Back to normal
Switch back when it's fixed
When Microsoft 365 recovers, point mail routing back to it. The standby stays ready, and we go through the day with you to tighten the runbook.
What stays working
Email keeps flowing
Point your mail routing to Google and new messages arrive in Gmail while Outlook is down.
Meetings and chat
Google Meet and Chat for calls and quick decisions, with no Teams needed.
Documents and files
Drive, Docs, Sheets and Slides for the work that can't wait for Microsoft to come back.
Your recent mail and calendar
On Business Continuity Plus, synced email, calendar events and chat messages can be there when people sign in.
Proper security
A separate environment with Google's security controls, security keys recommended and Google Vault included.
Tested before you need it
Google allows up to four failover tests a year. We run them with you, so the real day is a routine.
Getting ready, in four steps
01
Plan
Decide who needs standby access, which edition fits, and what counts as an outage for your business.
02
Set up
We create the accounts, sync your directory, set up data sync on Plus and lock it down with security keys.
03
Rehearse
A failover test with your team, and a one-page runbook for who switches what, and when.
04
Keep it current
Directory and data sync need upkeep. We keep them current and rerun the failover test, so the standby is always ready.
An outage day, with and without a standby
| Area | With a Google Workspace standby | Without one |
|---|---|---|
| With a Google Workspace standby: Mail routes to Gmail and keeps arriving | Without one: Wait, and hope nothing important bounces | |
| Meetings | With a Google Workspace standby: Google Meet, links sent from Gmail | Without one: Phone calls and personal accounts |
| Documents | With a Google Workspace standby: Drive and Docs for urgent work | Without one: Locked out of OneDrive and SharePoint |
| Security | With a Google Workspace standby: A managed environment with security keys | Without one: Staff improvise with personal apps |
| Who decides | With a Google Workspace standby: A runbook you've rehearsed | Without one: Decided under pressure, on the day |
Common questions
Do we have to move off Microsoft 365?
No. Microsoft 365 stays your main system. The Google Workspace standby is only used when Microsoft 365 is down, and you switch back when it recovers.
Isn't this the same as a backup?
No. A backup lets you restore data after something is lost. Continuity keeps people working during the outage itself. Most businesses need both.
How does the switch work on the day?
Your admin points your domain's MX records to Google so mail routes to Gmail, then tells your team to sign in. We set this up and rehearse it with you beforehand, so it's a known routine rather than a scramble.
Which edition do we need?
Business Continuity suits leadership and critical teams who can start fresh for a few days. Business Continuity Plus suits teams that need their recent email, calendar and chat to be there. We'll help you choose.
Are there limits on how long we can use it?
Yes. Business Continuity allows up to 7 consecutive days and 21 days a year; Plus allows 30 consecutive days and 60 a year. Admin work and syncing aren't limited, and you can run up to four failover tests a year.
Does it have to be set up in advance?
Yes. Google designed it to be deployed before a disruption, not as a recovery option once one has started. The best time to set it up is before the next outage.
Is it only for large companies?
No. It's sized to the people who need it: you can cover only your leadership and the teams who talk to customers. A small business can be ready without changing how it works every other day.
What does D3V do?
We plan it with you, set up the accounts, directory and data sync, secure the environment, write the runbook and rehearse the switch. Google recommends working with a partner for the sync, and that's the part we handle.
