Microsoft Sync
Native Microsoft sync – a one-click connection for Outlook.com, Hotmail, and Microsoft 365 that keeps your mail, calendar, and contacts mirrored automatically, the same way Google Sync works – is in active development. Until it ships, you can move everything across today with an IMAP import.
Today: import over IMAP
Connect with an app password
Microsoft mailboxes are reachable over IMAP at outlook.office365.com on port 993. If your account uses two-step verification, generate an app password in your Microsoft security settings and use that as the password.
Then start an IMAP import in Settings → Sync & Import. The full walkthrough, including where to find the app-password setting, is in the Switch from Microsoft guide.
Calendars and contacts
Microsoft doesn’t expose calendars and contacts over IMAP, so export them from Outlook on the web and import them into Cirrux separately – calendars as .ics files, contacts as a vCard. The Switch from Microsoft guide covers the export steps.
Keeping up to date
An IMAP import is a one-shot copy, so re-run it to pull in new mail. During the transition, set an automatic forward in Outlook so new messages reach Cirrux in real time – see the cutover notes in the IMAP import guide.
Coming soon: native sync
What native Microsoft sync will add
Native sync will connect to your Microsoft account with a single authorization – no app passwords, no manual calendar and contact exports, and continuous background updates instead of one-shot imports. When it lands, you’ll be able to switch over from your IMAP connection without losing anything you’ve already imported.
