days until support ends
AWS ends support for Amazon WorkMail on 31 March 2027. After that date you can no longer use the WorkMail console or WorkMail itself, so every mailbox on it has to move to another provider first. WorkMail also closed to new customers on 30 April 2026. This free checker reads a domain's public DNS — its MX record and its AutoDiscover record — and tells you whether that domain is actually on WorkMail, which AWS region it sits in, and how many days remain before support ends.

How this check works
Proof
The AutoDiscover record
WorkMail publishes autodiscover-service.mail.<region>.awsapps.com. No other AWS service does, so finding it is proof the domain is on WorkMail.
Not proof
The MX record
inbound-smtp.<region>.amazonaws.com is published by WorkMail and by any plain Amazon SES receipt rule. Alone it means "mail goes to AWS", not "this is WorkMail" — so we report it as possible, never as confirmed.
Two read-only lookups, no account, nothing stored. Closed to new customers since 30 April 2026; support ends 31 March 2027.
Questions
When exactly does AWS WorkMail shut down?
AWS ends support for Amazon WorkMail on 31 March 2027. After that date the WorkMail console and WorkMail itself can no longer be used. WorkMail also stopped accepting new customers on 30 April 2026, so the service is already closed to new signups.
How do I tell whether my domain is actually on WorkMail?
Two public DNS records decide it. WorkMail publishes an MX record pointing at inbound-smtp.<region>.amazonaws.com, and an AutoDiscover CNAME pointing at autodiscover-service.mail.<region>.awsapps.com. The MX on its own is shared with plain Amazon SES receiving, so only the AutoDiscover record proves WorkMail. This checker looks at both and tells you which of the two it found.
What happens to my email if I do nothing?
Mail delivery depends on the service AWS is switching off, so inbound mail to those mailboxes stops working once support ends. Anything held only inside WorkMail — mailbox contents, calendars, contacts — needs to be exported before you lose console access, because the console is how you export it.
What does AWS recommend moving to?
AWS's own end-of-support notice names three alternatives: Kopano Cloud, Zoho Mail, and Zoom Mail, and links a guide for exporting mailboxes. Those are worth evaluating alongside Google Workspace and Microsoft 365, which is what most WorkMail-sized teams compare against in practice.
Is this checker free, and do you store my domain?
It's free and needs no account. It reads public DNS only — the same two records any mail server can already see. Nothing about the domain is stored.
Where does Folio fit?
Folio is a good fit if the domains outnumber the people: several custom domains, a small number of actual mailboxes, and no need for a full office suite. If you need many staff mailboxes with shared calendars and documents, Google Workspace or Microsoft 365 will fit better — we say so on our comparison page rather than pretending otherwise.
