When your organization transitions from Google Workspace to Microsoft 365, you'll need to update your calendar connection in Fellow to maintain access to your meetings and notes. This process is straightforward, but requires coordination with your IT team to ensure your calendar data is migrated properly before making the switch in Fellow.
Before You Switch: Critical Preparation Steps
⚠️ Important: Work with your IT team BEFORE switching calendars in Fellow!
To ensure a smooth transition and preserve your meeting notes and calendar data:
Step 1: IT team migrates calendar data
Your IT team must first transfer your calendar events from Google Calendar to Microsoft 365. This migration should preserve calendar event IDs to maintain the connection between your meetings and Fellow notes.
Critical for data preservation:
Calendar event IDs must be preserved during migration
Existing calendar events need to transfer to Microsoft 365
Verify the migration is complete before switching in Fellow
Step 2: Verify calendar data in Microsoft 365
Before disconnecting Google Calendar in Fellow:
Confirm all your calendar events appear in Microsoft 365
Check that recurring meetings transferred correctly
Ensure meeting details (attendees, times, descriptions) are intact
Why this matters: Fellow uses calendar event IDs to link meetings to notes. If the migration doesn't preserve these connections properly, you may lose access to historical meeting notes.
What Happens When You Switch Calendars
Understanding the impact of switching helps you prepare:
What is preserved:
Existing meeting notes remain accessible
Historical action items stay intact
Meeting series continue (if calendar events are properly migrated)
User settings and preferences
What requires attention:
Calendar sync must be reconnected
Existing calendar events must be migrated by IT first
You can only have one calendar type connected at a time (Google OR Microsoft, not both)
How to Switch from Google Calendar to Office 365
Once your IT team has completed the calendar migration, follow these steps to update your calendar connection in Fellow:
Step 1: Open user settings
Click on your profile icon in the bottom left corner of Fellow
Select User Settings from the menu
Step 2: Navigate to Apps & Integrations
In User Settings, click on Apps & Integrations in the left sidebar
Scroll to the bottom of the page to find the Calendar Sync section
Step 3: Disconnect Google Calendar
In the Calendar Sync section, hover over Google Calendar
Click on the three vertical dots that appear
Select Disconnect
Confirm you want to disconnect
Note: Make sure your IT team has completed the calendar migration to Microsoft 365 before disconnecting Google Calendar.
Step 4: Connect Microsoft 365 Calendar
In the Calendar Sync section, hover over Microsoft 365 Calendar
Click on the three vertical dots that appear
Select Connect
Follow the prompts to authorize Fellow to access your Microsoft 365 calendar
Accept the requested permissions
Step 5: Wait for sync to complete
Fellow will begin syncing your Microsoft 365 calendar. This may take a few minutes. Once complete, you'll see your calendar events appear in Fellow.
After Switching: Verifying Your Calendar Sync
After connecting your Microsoft 365 calendar, verify everything is working correctly:
Check your calendar:
Navigate to the Meetings tab in Fellow
Verify your calendar events are appearing
Confirm recurring meetings are showing correctly
Check existing notes:
Open a meeting note from before the migration
Verify the note is still linked to the calendar event
Check that action items and content are intact
Trigger a manual sync if needed:
Click the sync button at the bottom of the calendar page if events aren't appearing immediately
Troubleshooting
Calendar events not appearing after switching
Possible causes:
Calendar sync hasn't completed yet (wait a few minutes)
IT team hasn't fully migrated calendar data
Calendar permissions weren't granted during connection
Solutions:
Click the manual sync button at the bottom of the calendar page
Try disconnecting and reconnecting Microsoft 365 calendar
Verify with IT that calendar migration is complete
Check that you accepted all permissions during the connection process
Lost access to old meeting notes
If you can't access meeting notes from before the switch:
Cause: Calendar event IDs changed during migration, breaking the link between calendar events and Fellow notes.
Solution: Contact Fellow Support with specific meeting examples. In some cases, the Fellow team may be able to help reconnect notes to migrated calendar events.
Can't see Microsoft 365 connection option
Cause: You may still have Google Calendar connected, and Fellow doesn't support connecting both calendar types simultaneously.
Solution: Disconnect Google Calendar first, then the Microsoft 365 option will become available.
Need to use both Google and Microsoft calendars?
Individual users can only connect one calendar type (Google OR Microsoft 365) to their Fellow account. However, your workspace can support users with different calendar types - some using Google, others using Microsoft 365. See
Multiple Calendars - what type of calendars do we support?
Calendar permissions errors
If you receive permission errors when connecting Microsoft 365:
Ensure you're using an Office 365 account (not Microsoft Exchange)
Verify your IT admin has granted calendar permissions
