Update Your Microsoft Account

Microsoft is turning off Exchange Web Services (EWS), an older way for email apps to connect to Office 365 (Microsoft 365) mailboxes. If BlueMail shows the Update your Microsoft account card, the account it names still connects through EWS. A quick update moves it to BlueMail's new Microsoft connection, so you keep getting mail. If your Office 365 mail has already stopped and you see no card, start with Office 365 mail stopped, and no card? below.

Update from the card

Before you start, check this account's Outbox and Drafts. BlueMail moves mail it can't send to Drafts, and if this account has stopped syncing, anything you wrote since may exist only in BlueMail. Copy anything you still need, for example into a note.

1. Tap Update now on the card.
2. Microsoft's own page opens. If you're already signed in to Microsoft on this device, it may just ask "Are you trying to sign in to BlueMail?": tap Continue. Otherwise, sign in with [your address] and your usual password, plus any extra check, such as an authenticator app. If Microsoft asks you to let BlueMail access your account, accept.
3. Keep BlueMail open and on screen until it's finished. You'll see "Updating [your address]…", and for a few seconds the account may disappear, or BlueMail may show another of your accounts. That's part of the update.
4. When "Account updated" appears, tap OK. You're done, and the card goes away.

Your email stays in your Microsoft mailbox the whole time. The account keeps its address and settings. BlueMail downloads your mail again, so folders may take a little while to fill.

Closed the card? Tapping ✕ hides it for 24 hours. It comes back every day until the account is updated, and you can also update from Settings at any time (below).

Update interrupted, and the account still isn't back when you open BlueMail again? Add it back as described under Remove the account and add it back below, starting at step 4.

Update from Settings

You can start the same update from Settings, for example after closing the card. Check the account's Outbox and Drafts first, as above.

1. Go to Settings | Accounts. An account that needs the update has a ⚠ warning sign next to it.
2. Tap that account, then tap Update your Microsoft account at the top of its screen.
3. Continue on Microsoft's page and wait for "Account updated", as in steps 2 to 4 above.

Do all my accounts need this?

No. Only Office 365 accounts that still connect through EWS do. Mailboxes on your company's own Exchange server (on-premises Exchange) aren't affected: Microsoft isn't changing EWS there, and BlueMail doesn't show the card for them. A mailbox in Microsoft 365 is affected even if your company also runs its own server. Not sure where yours is? Your IT department can tell you.

Each affected account gets its own card, in that account's mail list, and a ⚠ next to it in Settings | Accounts. Its screen there also names the connection: Office365 - EWS before the update, Office365 - MSO after. No card and no ⚠, and the account's mail is arriving normally? Nothing to do for that account but keep BlueMail updated.

If the update doesn't finish

"We couldn't update your account" means the update didn't finish, and the card stays. Work through these in order:

1. Try again. Check your internet connection, then tap Update now again.
2. Did Microsoft's sign-in show a message from your organization, such as admin approval needed or access blocked? Then only your IT department can fix it, not the app. Send them this page: its For IT administrators section has what they need. Keep the account while you wait, because adding it back would hit the same block. Once they've sorted it, tap Update now again.
3. Signed in with no message from Microsoft, and it still fails? Remove the account and add it back, as described under Remove the account and add it back below.

If your organization won't allow BlueMail, this account can't move to the new connection. It keeps syncing only while your organization still allows EWS for BlueMail, and stops by 1 April 2027 at the latest.

Office 365 mail stopped, and no card?

1. Update BlueMail. Older versions don't show the card, and updating keeps your accounts, mail and settings.
2. Look for the Update your Microsoft account card in that account's mail list (if you have more than one account, select it first), or a ⚠ next to it in Settings | Accounts. If either is there, update as described above.
3. No update available, or no card and no ⚠? Remove the account and add it back through Office 365, as described next.

If the account isn't an Office 365 account, see Connection Issues, Sync Failures or Missing Emails instead.

Remove the account and add it back

This also moves the account to BlueMail's new Microsoft connection. Unlike Update now, it may not keep the account's settings, such as its name, color or aliases. If your organization needs to approve BlueMail, adding the account back needs that approval too. Not sure whether it does? Ask your IT department before you remove the account.

1. Copy anything you still need from this account's Outbox and Drafts. Mail that BlueMail couldn't send may exist only in BlueMail, and removing the account deletes it.
2. Go to Settings | Accounts | [your address], scroll to the bottom and tap Remove Account.
3. BlueMail asks you to confirm: "This will delete the account and all it's emails." That's BlueMail's copy. Everything already in your Microsoft mailbox stays there and downloads again when you add the account back. Tap Yes.
4. Open the Add Account screen:
   • If other accounts are still in BlueMail, go to Settings | Accounts | Add Account.
   • If BlueMail opens on its welcome screen, tap Continue.
5. Tap Having trouble? Manual Setup under the Sign in button. In BlueMail on a computer, it's a Manual Setup button.
6. On the Choose provider screen, tap Office 365 and sign in with Microsoft.
7. If Microsoft's sign-in shows a message from your organization, such as admin approval needed, send your IT department this page. Once they've sorted it, repeat steps 4 to 6.

Why Microsoft is turning off EWS

Microsoft is retiring EWS for Office 365, partly for security reasons. Once your organization stops allowing EWS for BlueMail, an account still on EWS can't sync, and new mail stops arriving.

• Starting 1 October 2026, Microsoft began turning EWS off, one organization at a time.
• Some organizations haven't been switched yet, or still allow EWS for apps they've approved, so your mail may still be working today.
• On 1 April 2027, Microsoft turns EWS off permanently, for every organization.

On whether that date can be extended, Microsoft's Exchange Team says:

There will be no exceptions past April 2027.

Microsoft's own announcement, written for IT administrators: Exchange Online EWS, Your Time is Almost Up.

For IT administrators

BlueMail's new Microsoft connection uses Microsoft Graph, Microsoft's replacement for EWS. If your organization requires admin consent for third-party apps, your users can't finish the update until you grant it, once, for the whole organization:

1. In the Microsoft Entra admin center, open Enterprise apps and select BlueMail. If it isn't there yet, add it first, as in our guide to approving BlueMail for Office 365.
2. Select Permissions, review them, and select Grant admin consent.

Microsoft's full steps: Grant tenant-wide admin consent to an application.

Still stuck?

If the account updated but mail still doesn't arrive, see Connection Issues, Sync Failures or Missing Emails. Otherwise, email support@bluemail.me with the account's address, the exact message you see, and whether Microsoft's sign-in showed a message from your organization.
