1. 1. Confirm calendar sync is on

   Copy steps
   1. As an admin open Admin > Integrations and select Google Workspace or Microsoft 365
   2. Enable user sync, email sync and calendar sync as needed
   3. Have the interviewer reconnect their calendar if access expired
   Did this fix it? Yes No

2. 2. Use one calendar provider

   Copy steps
   1. Ashby cannot run Google and Microsoft together
   2. Pick the provider that most interviewers use and move the rest or use shared calendars
   Did this fix it? Yes No

3. 3. Check status and unsent invites

   Copy steps
   1. Look at status.ashbyhq.com for Delayed Email and Calendar Sync incidents
   2. Send invites for interviews that were booked but not sent, as they block availability
   Did this fix it? Yes No

Symptoms

Interviewer availability is wrong, meetings made outside Ashby do not block time, or invites do not appear on calendars.

Why it happens

• Calendar sync not enabled in the Google Workspace or Microsoft 365 integration settings
• Ashby does not support Google and Microsoft integrated at the same time
• Delayed sync during maintenance or incidents (June and August 2025 incidents)
• Recurring events not considered in past incidents
• Interviews booked in Ashby but invites never sent still block time
