Sync with Microsoft To Do
Microsoft To Do sync is not available in public versions of 2Do yet. This page previews support planned for Mac, iPhone and iPad.
Sync your lists and tasks between 2Do and Microsoft To Do. Use your personal Microsoft account, such as Outlook.com, or a supported Microsoft 365 work or school account. Changes made in either app appear after the next sync.
These steps preview Microsoft To Do setup in an upcoming version of 2Do for iPhone and iPad. It is not available in 2Do for Android or 2Do for Web.
Before You Connect
Sign in to Microsoft To Do with the account you plan to use and check that your lists are available. Work and school accounts need a supported subscription and an Exchange Online mailbox. An on-premises Exchange mailbox alone does not provide Microsoft To Do sync. See Microsoft's account requirements.
2Do connects to Microsoft's standard cloud service. Deployments that require separate national-cloud sign-in or Graph addresses are not supported.
Use the same Microsoft account in 2Do on each device. 2Do uses one ordinary sync account at a time; disconnect another sync account before choosing Microsoft To Do. iCloud shared lists use their own connection and stay separate.
Connect Your Account
- Open Settings from the gear at the bottom of the list panel, then choose Sync > Setup.
- Choose Microsoft To Do from Account Type.
- Tap Set Up Sync. Sign in on Microsoft's page and allow 2Do to access your tasks and read your mailbox settings.
- When both 2Do and Microsoft already contain tasks, choose Merge to keep data from both sides. Choose Replace Local Data only when the Microsoft account has the copy you want to use on this device; local syncable data may be removed.
- Repeat these steps on your other Apple devices with the same Microsoft account.
2Do reads your mailbox time zone to interpret native task dates consistently across devices. This permission does not give 2Do access to your email messages.
Microsoft handles the password and any verification steps. 2Do saves the account authorization so normal sync does not require signing in each time. If your organization requires administrator approval, ask its administrator to allow 2Do. If Microsoft later revokes access, sync again and choose Authenticate when 2Do asks. Signing in with the same account keeps your sync history and pending changes.
Replace Server Data is not offered for Microsoft To Do. A merge keeps existing tasks on the service. Read Merge vs Replace before choosing a replacement.
What Syncs
Your regular lists, tasks, notes, completion state, dates, tags and supported files sync through the Microsoft account. Microsoft's default Tasks list appears as 2Do's Inbox. The Flagged Emails list is read-only in 2Do.
2Do also saves its extra task details with each task, including due times, start times, actions, additional alarms, locations and parent links. Another 2Do device reads those details without adding metadata text to your notes. Microsoft To Do does not display these extra fields.
A 2Do project or checklist and its children appear as separate tasks in Microsoft To Do. Their links are restored in 2Do. If you move or delete only the parent in Microsoft To Do, surviving children stay in their current list as standalone tasks in 2Do. Deleting a project or checklist in 2Do also deletes its children. Microsoft's own checklist steps are not 2Do sub-tasks and are not imported as separate tasks.
List groups, Smart Lists and sections stay on the device. Tags and locations attached to tasks travel with those tasks; unused tags, unused locations and empty tag groups do not sync as separate items. Expand What syncs across your devices in Settings > Sync for the account's summary.
Dates, Times and Alarms
Microsoft's task service keeps start and due dates without their clock times. 2Do saves its start and due times separately, so they survive between your 2Do devices. Microsoft To Do and Outlook may therefore show a due date without the due time you see in 2Do. A start date without a due date stays in 2Do's extra details so Microsoft does not add an unwanted due date.
Microsoft sometimes returns a date as midnight in your mailbox time zone, converted to UTC. 2Do uses the mailbox setting to interpret that date. Microsoft does not always expose the original time zone of a task created elsewhere, so a task created in a different zone can still appear on a different day. Check the date in both apps if you use Microsoft clients with different time-zone settings.
Microsoft provides one native reminder per task. 2Do projects one of its alarms into that reminder and saves the rest for your other 2Do devices. Changing or removing the reminder in Microsoft changes that projected alarm; the additional 2Do alarms remain separate.
Repeating Tasks
When Microsoft can represent a task's repeat rule, it can repeat in either app. 2Do also preserves rules that Microsoft cannot represent exactly, including completion-based repeats, separate start and due days, and some manually rescheduled occurrences. Complete those tasks in 2Do to advance the rule. Microsoft To Do shows them without a native repeat setting.
See Repeating Tasks for 2Do's repeat options.
Attachments
Files up to 25 MB can sync. Larger files and link-only attachments remain on the device, and the rest of sync continues. If you replace an already-synced file with an unsupported file, Microsoft keeps the previously uploaded version until you choose a supported replacement.
If Sync Cannot Connect
Check Last Error in Settings > Sync. Confirm that Microsoft To Do works with the same account, and check with your administrator if access or licensing has changed. Do not enter a mail-server address or an Exchange password into another sync method; Microsoft To Do uses the Microsoft sign-in page.
Microsoft can temporarily limit requests. 2Do respects those responses and retries through its normal sync handling. If the limit lasts longer than the current sync, leave the account connected and try syncing later.
