Development builds / Re: Microsoft Graph Support Now Available in the Latest Aqua Mail Beta

« Last post by JSSMarathon on August 07, 2026, 01:07:13 am »

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

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?

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

Any else?

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

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.

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

I am allegedly a pro user (lifetime license user from the unlocker app era) and now am getting ads, promoting other aqua mail inc products.

So.. is this how we roll from now on?

New AM update for Android is horrible.  All my inbox does is spin then times out. 

19 hours & counting.

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.
