Microsoft 365 mailbox

In onOffice enterprise, Microsoft 365 mailboxes / Exchange mailboxes that are located at Microsoft can be connected using Microsoft’s own format (Microsoft Graph).

The mailboxes are configured in the e-mail administration in the tab “external IMAP mailboxes”. You can activate the same options as for internal mailboxes after creation.

onOffice App !

Microsoft 365 mailboxes are currently not yet available in the onOffice app.

Include Microsoft 365 mailbox

The setup is divided into 2 parts, the “Create” with the user assignment and the “Authenticate” with the Microsoft account to get the access.

For mailboxes that are not located directly at Microsoft (@outlook.de/@outlook.com), access from onOffice via the MS Graph interface may have to be enabled. This must be done by the administrator of the mailboxes.

Create

The mailbox is created in the basic settings, if you do not have the user right for the basic settings please contact your administrator.

To create the mailbox please open the e-mail administration (Tools >> Settings >> Basic settings >> E-mail) and there the tab “external IMAP mailboxes”.

Please enter the complete mailbox in the category “IMAP Import” at “e-mail contact” and click on “import office 365”.

This will create the mailbox in the list and you can assign users toit.

ATTENTION, all users assigned here can later access the contents of the mailbox even if they do NOT have access to the Microsoft account.

Authenticate / Log in

ATTENTION, after authentication all assigned users can access the content of the mailbox, even if they do NOT have access to the Microsoft account.

In the E-mail module you can now open the newly created mailbox.
When you first open it, the familiar Microsoft account login screen appears.

Please enter the password in the imported mailbox dialog and approve the access for onOffice.

Please remember, if you access a mailbox with several e-mail programs at the same time, there can always be differences in the folder structure, number of read e-mails, etc. This applies generally and not only to Microsoft 365 mailboxes.

New outbox: After authentication, it may happen that the outbox changes: Outgoing e-mails are saved in the Sent Items folder and no longer in the onOffice Sent Items folder. If you want outgoing e-mails to appear under “Sent Items” as before, please follow these steps:

In the Outlook interface, move all e-mails from the Sent Items folder to the Sent Items folder.
Clear the onOffice cache via “Tools >> Settings >> Clear Cache”.
