Terminology

Outlook	Missive
Folders	Labels
Categories	Not supported
Flags	Not supported
Recall a message	Undo send
Favorites	Sidebar sections
Archive Folder	All mailbox
In-Place Archive	Not supported

Folders vs Categories: In Outlook, folders and categories serve different purposes. Folders store emails in specific locations and sync to Missive as labels. Categories are color-coded tags that don't affect storage location and don't sync to Missive.

History

When you connect an Office 365 account to Missive, you choose how much email history to import. This can be changed later in settings.

All emails retain their read/unread status and location (inbox, folders, etc).

Paid plans allow importing unlimited history.

Contacts

Missive syncs your Outlook contacts automatically with full two-way sync.

If auto-sync was disabled, re-enable it:

1. Go to Settings > Accounts

2. Select your Office 365 / Outlook account

3. Click Contacts

4. Click Sync contacts

Calendar

Connect your Office 365 / Outlook calendar:

1. Go to Settings > Calendars

2. Click Add a calendar account

3. Select Office 365 or Outlook

4. Sign in and follow the prompts

Shared mailboxes

Office 365 shared mailboxes work like any shared account in Missive:

1. Go to Settings > Accounts and click Add account

2. Select Office 365 or Outlook

3. In the Microsoft popup, select an account that has access to the shared mailbox

Distribution lists / Groups

Office 365 groups (distribution lists) forward emails to recipients' personal inboxes - they can't be connected directly. Use Missive's Shared addresses feature instead.

Go to Settings > Organizations > Message sharing to set up shared addresses.

See Google Group address for setup instructions - the process is identical for Office 365 groups.
