How to add an Office 365 inbox/shared mailbox to Front


Front has a two-way sync with Office 365 (O365) inboxes, which means that conversation statuses will sync between the two, as well as all incoming and outgoing mail. Read on for the specifics of how the sync works. If you already have an SMTP setup for your Office 365 account, see this article on how to transition.


Step 1

Click into Settings, then Inboxes, and click Add a team inbox or Add an individual inbox.

Step 2

You will see a list of options for the type of channel you can create. Click Email.

Step 3

Type in your email address and click Next

Step 4

You will be asked to chose between an Office 365 account or a Forwarding address setup. Click the Office 365 account / Office 365 shared mailbox.

馃毃Troubleshooting: Sometimes Front cannot detect your Office 365 domain if you have certain security measures in place. If your screen does not show the above options and instead shows a forwarding setup, then go back to Step 3. This time, hold down the SHIFT key while clicking Next to trigger an Office 365 sync channel to be created.

Step 5

You will see a pop-up window to sign in to your Office 365 account.

Note: if you are adding an Office 365 shared mailbox account, you must be a member of that shared mailbox in Outlook and have 'Read and Manage' and 'Send as' permissions. If you do not have access to it, the authentication will fail.

馃搷Important: The person who signs in and authenticates this inbox will have their account tied to this channel. If they change their password or their user account is deleted in Office 365, the channel will stop syncing. If that happens, an admin will need to go into the channel settings to re-authenticate the channel to bring it back online.

Step 6

If you're creating a team inbox, you will see a section titled Import. In this section, you can:

  • Choose to import all historical conversations, or do not import any historical conversations
  • Choose to import and sync all folders or labels, or import/sync no folders or labels

If you do not wish to import these items, turn the toggle(s) off.

Step 7

Then give your teammates access to the new team inbox, and click Create inbox.

Step 7

You can now see the inbox with the new Office 365 channel in your Front dashboard. Now the actions you take in Front within this channel will sync back to your Office 365 account and vice versa.


How will Front sync with Office 365?

Check out the full breakdown here.

Folder setup

The default folders that need to exist in your Office 365 account, in order to successfully complete your sync, are: Inbox, Drafts, Sent Items, Deleted Items, Junk Email, and Archive. If you rename one of these folders or if a message is in a customized folder or part of a shared mailbox, Front will tag the conversation with the name of the folder when it syncs over. If you experience an error referencing missing required folders, please email us at

What happens to my shared and private folders from Office 365?

Front has a one-way sync for user-created Office 365 shared and private folders, which sync to Front as shared/private tags (including nesting) within an inbox.

Outgoing display name

Office 365 does not support setting a different display name for the From address when sending an email. It uses the name set on your Office 365 account. 


The person who signs in and authenticates the inbox will have their account tied to this channel. If they change their password or their user account is deleted in Office 365, the channel will stop syncing. If that happens, an admin will need to go into the channel settings to re-authenticate the channel to bring it back online.

Automatic history import

When you connect an Office 365 email account to Front, we will automatically import your most recent 50K messages.

What permissions do I need to connect an O365 Shared Mailbox?


Whoever is connecting the shared inbox to Front needs to have:

  • "Edit, Read, and Manage" permission
  • "Send As" permission
  • "Send on behalf of" permission

  • After connecting to the "office365 account" does it take a while before it starts the syncing process? How long does it take?

    I see only new emails coming in directly, but it doesn't show me any email which came into the office365 account from before I connected it to Front.

  • Joep Mutsaerts Hey! Your email history doesn't sync automatically, but we can run the import for you manually. Please send an email to and let us know what inbox you'd like to import from.

  • OK, thank you. I did that and it is working like a charm. Cheers

  • Hello,

    I have synced my 365 mailbox with front. When I archive an email in front it disappears from my mailbox. Where does it go?

    Also I would love to be able to see and manipulate my inbox subfolders from front as well.

  • Aaron Miller Hi Aaron, so sorry that we missed this comment when you first posted it. Feel free to email us at in the future if you have specific questions about your account. To answer your question, archived messages go in the "All" section of your inbox list. Currently you aren't able to edit your O365 folders from Front, as O365 is the "owner" of these folders so you have to make edits there.

  • Hi, I am trying to set up Front synced with Office 365 and I do not like the fact that it syncs with the archive folders without allowing me to see that archive folder structure within Front.  I have many rules that automatically allocate inbound emails to archive folders and because Front presents emails even after being archived, I have to deal with them again in Front.  Is there a plan to either add archive folders to Front along with the ability to move emails to an archive folder (the most ideal answer) or to exclude Archive so I don't have to deal with email in Front even if they've already been moved in Outlook?

    I love what Front is able to do for my employees that must work a shared inbox as part of their regular duties, but for those that infrequently will check Front, the best way to get them to do that is to move them from Outlook to Front but with the way emails in the Archive folder are handled, I am not going to get buy-in from my users.

  • I need someone from Front technical development to contact me ASAP.  Front treated EVERY item in my Office 365 mailbox as one bucket and when I said I wanted to Archive everything older than today it is now taking EVERY item that I put into my folder structure and moving it into Office 365's default Archive folder.  This is insane! 

    I deleted the Front integration for now to hopefully stop it from completely ruining all of the sorting I've done over the years (it still hasn't stopped) but I need a much better understanding of what's going on before I can consider Front as an acceptable email client for Office 365.

  • As a followup, I am going to try moving all of my archived folders to Office 365's Archive instead of my older custom folder.  I'll report what effect this has, it might be what's needed for Front to not require me to touch emails that have already been moved (now to the Archive folder). Thanks.

  • After moving all of my archived folders to the Archive folder, I re-added my Office 365 account to Front and new content being put into the Archive sub-folders is still seen in my Front Inbox for my Office 365 account as open items.

    The inability of Front to let me organize how I archive things or even honor the Archiving of items into sub-folders make Front a pretty limited email client that I doubt I can use.  I'd like to discuss the possibility of a feature enhancement to make it work for people that need to sort archived information within their Mailbox.
