Capsule and Outlook: what syncs, what doesn't, and how to set it up
Capsule's Outlook add-in stores email threads on contacts and creates records from the inbox. A separate calendar link shows Outlook events in Capsule, read-only. Both need email hosted by Microsoft 365.
- Connector
- Native add-in built by Capsule, included on all plans with no separate charge listed, installed from Microsoft AppSource
- Sync direction

- Our rating
- 4 out of 5. Email storing and a calendar view on every plan; the calendar is one-way and automatic email storing needs Growth.
| What | Direction | Detail |
|---|---|---|
| Email conversations | Outlook → Capsule | You store a thread on a contact, opportunity or project. Capsule then adds every later message in that thread, sent and received. |
| Automatic email storing | Outlook → Capsule | Growth, Advanced and Ultimate only. You enable it per contact. Capsule stores all emails to and from that contact, and can also store earlier emails. |
| New contacts | Outlook → Capsule | You add the sender as a person or organization from the sidebar, or match them to an existing contact. Matching saves the new email address on that contact. |
| Contact details in the sidebar | Capsule → Outlook | For an existing contact, the add-in shows what you have recorded in Capsule. It also lists the other contacts in the conversation. |
| Opportunities, projects and tasks | Outlook → Capsule | You create them from the email, attached to the contact. The add-in works only on an open email, not in the list view or the compose window. |
| Calendar events | Outlook → Capsule | Events from one chosen calendar appear in Capsule's calendar and on the sidebar of any contact whose email address matches an attendee. Edits made in Outlook pass through. |
| Meeting activities | Outlook → Capsule | You save an event as a Capsule activity. It defaults to the Meeting type, and the report dates it by the day you logged it. |
Setting it up
- In Outlook for Microsoft 365, open an email and choose Get Add-ins. Search for Capsule, click Add, and agree to the terms. You can also use the AppSource link.
- Open an email, expand Capsule from the More actions menu, and click Connect your Capsule account. Sign in to Capsule.
- Click Grant access to Microsoft 365 and accept the permissions. Capsule asks once per user.
- Pin the add-in with the push pin, or tick Capsule under Message Surface in Outlook's Customise Actions settings.
- In Capsule, go to My preferences > Calendar and feeds and click Connect to Microsoft Outlook. Sign in, choose a calendar and confirm.
- Wait a few minutes for the first sync. Ask each user to repeat the calendar steps for their own events.
Where the integration stops
- Microsoft 365 hosting is required to store email. The add-in installs for any Microsoft 365 user. Storing is greyed out for Personal or Family subscriptions, self-hosted Exchange and GoDaddy subscriptions.
- The calendar is read-only in Capsule. You edit or schedule events in Outlook, and Capsule opens Outlook in a new tab. Capsule events do not appear in Outlook.
- One calendar provider per Capsule account. If one user connects Outlook, no user can connect Google Calendar, and the reverse. Each user connects their own calendar.
- Automatic storing is narrow. It needs Growth or above, stores on contact records only, and skips emails where the contact is in CC or BCC.
- Your Outlook events are visible only to you in the Capsule calendar. Other users see them on contact records. Private events reach only attendees who have connected a calendar.
Capsule's Outlook add-in files email threads on Capsule records and creates contacts, opportunities, projects and tasks from the inbox. A separate calendar integration shows Outlook events on contact records. It suits small teams on Microsoft 365 that want email history in Capsule without copying it by hand.
Email hosting is the fact that most often surprises teams. Any Microsoft 365 user can install the add-in. Storing email works only when Microsoft 365 hosts the mailbox, and the option is greyed out otherwise.
The calendar side is one-way. Capsule reads your Outlook events and cannot change them.
Email storing works per thread, and automatic storing needs Growth
On every plan, you store a conversation from the sidebar. Capsule then adds each later message in that thread to the record, sent and received. You can store a thread on a contact, an opportunity or a project.
Automatic storing is the larger step. It works per contact and is available on Growth, Advanced and Ultimate. Capsule saves every email to and from that contact, and can also pull in earlier emails. It stores them on the contact record only, and it ignores emails where the contact is in CC or BCC. See Capsule pricing for what the plans include.
The add-in also creates records. From an email you add the sender as a person or organization, or match them to an existing contact. You can then add an opportunity, project or task without leaving Outlook.
The calendar is a view, not a sync
Once connected, Outlook events from one chosen calendar appear in Capsule's calendar. They also appear on the sidebar of any contact whose email address matches an attendee. Capsule shows a join button for Teams meetings and lets you save an event as an activity.
Capsule does not write back. You edit events in Outlook, and the change reaches Capsule afterwards. Events you create in Capsule do not appear in Outlook.
Each user connects their own calendar. Other users see your events on contact records, not in your Capsule calendar view.
One calendar provider per account
A Capsule account takes either an Outlook calendar or a Google calendar, not both. The setting covers every user. A team where some people use Google Calendar must pick one. Our Capsule and Gmail review covers the Google side.
The Outlook add-in and the calendar integration are separate connections. You can use the add-in for email without connecting any calendar.
What you still build yourself
Capsule's documentation describes no sync of Outlook's address book with Capsule contacts. Contacts arrive one at a time, from emails you open. Bulk contact movement needs an import or another tool, such as the route in our Capsule and Zapier review.
