Microsoft Graph Support Now Available in stable
« on: June 26, 2026, 12:17:19 pm »
Hello everyone,

With the latest Aqua Mail beta update, we have implemented the long-awaited Microsoft Graph support for Microsoft business accounts.

To continue using your Microsoft 365 / Office 365 business account in Aqua Mail, you will need to remove the account from Aqua Mail and add it again.

Is there any way to get past this page other than contacting our institional IT department and trying to get their permission to keep using Aquamail?

Hello Martin,

I updated the new Aquamail version but I have found problems. After I deleted my Office365 account and I added again the same Office365 account It seems that it was working fine, but, after some hours the account asked me again for the credentials and for giving access to contacts, calendar, etc. I gave it but for some reason, it didn't work.

Now, I am trying again, I hope it will work, but there is some things to fix. I am adding 2 examples, to show the outlook view and the Aquamail view. Aquamail is showing for some emails, many times the email address of the contacts used in the mail.

I noticed too that the calendar is syncing some events with error.

You will see that there is a repetitive event "Visita al Santísimo", it is shown in Saturday instead of Sunday.

Can I download the previous version? I hope it will be available.

Yes you will.

Not at the moment, but we will look for a possible solution.

We are currently investigating all reported problems, including this one. I will keep you updated on the progress.

Probably not. And if there is and your IT department catches you, there's a good chance you'll be terminated. If you're not allowed to use third-party apps by your company, then you're not allowed to use third-party apps.

I'm facing the same admin approval issue now. Were you using Azure AD Graph previously? I have to explain the change to our MS admins.

No, this change is not about Azure AD Graph. Azure AD Graph is a directory API and is being retired by Microsoft.

Aqua Mail has moved Microsoft 365 accounts to Microsoft Graph for mailbox access and modern OAuth authentication. Because this uses a new Microsoft app/API permission set, your tenant may require admin consent again, even if Aqua Mail or older access was previously approved.

Your admins should check Microsoft Entra ID > Enterprise applications and grant admin consent for the Aqua Mail Microsoft Graph permissions required for mail access. This approval is controlled by your organization’s Microsoft 365 security policy and cannot be bypassed by Aqua Mail.

Hi everyone,

after the latest update to 2.6.0-043 and switching to graph api, it is no longer possible to add shared mailboxes.
Even the migration of already existing shared mailboxes that were added by EWS in previous aquamail versions could not succeed.

I already granted admin consent for Aquamail in Microsoft Entra and made sure that the following permissions exist:
Calendars.ReadWrite.Shared
Contacts.ReadWrite.Shared
Mail.ReadWrite.Shared
Mail.Send.Shared

So, concerning the permissions everything ist ok in my opinion

Is anyone of you facing the same issues?

Regards

Justin

Hi everybody,

same issue for me: Can't login anymore via OAuth since update.

I'm afraid I can't use Aquamail anymore.

What other app is still working?

Same problem here with the shared mailboxes, and it's a huge issue as that's our on-call mailbox.  Adding a shared mailbox just creates a copy of my primary mailbox with the same content.  Using Outlook mobile for now to get through the day, but I absolutely hate it compared to Aquamail.

The "use current account" setting also seems to be broken.  :(  It sends from the default account even if composing from a different mailbox.

Found out - these apps are still working with Microsoft OAuth method:
- Thunderbird
- Fairemail
- Gmail
- Outlook (of course)

Any else?

I'm running into a send failure on my Office 365 account since today's AquaMail update, which appears to coincide with the Microsoft Graph migration mentioned in your forum thread "Microsoft Graph Support Now Available in the Latest Aqua Mail Beta."



Device: Samsung Galaxy Z Fold 7 (Android)

AquaMail version/build: [please fill in from Settings > About AquaMail]

Account affected: Microsoft 365 Business Basic account on a custom domain (Exchange/O365 account type)



Error message on send:

"Error sending outgoing messages: Invalid server response: RequestBodyRead: Requested value 'plain' was not found."



Details:

- This started immediately after installing today's update.

- It only affects the O365/Exchange account. My other two IMAP/SMTP accounts on the same device send normally.

- I've already confirmed in Microsoft Entra ID that admin consent for AquaMail's Microsoft Graph permissions has been granted at the tenant level (17 Microsoft Graph delegated permissions showing under the Admin consent tab), so this doesn't appear to be a permissions/consent issue.

- Incoming mail sync appears unaffected; it's specifically outgoing/sending that fails.



Given the error text references a "plain" value not being found during request body parsing, this looks like it could be a content-type/message-format enum mismatch introduced in the new Graph-based send path.
Also contact pictures and calendar colors are not sinking correctly
