Outlook calendar invites not sending or recipients not receiving them
Outlook is having trouble sending your invites. Check your internet connection, make sure Outlook is not in offline mode, and try sending again. If that does not work, restart Outlook.
Calendar invites fail to send when Outlook is offline, when your mailbox is having sync issues, or when the recipient list has an error. We will check your connection, make sure Outlook is online, and resend the invites.

- Assuming the recipient email is correct when there is actually a typo. Always copy and paste email addresses from the Global Address List instead of typing them.
- Trying to send an invite while Outlook is still syncing. Wait for the sync to finish before sending.
