Hi Jose,

Based on your description, the recipient receives the calendar sharing invitation as a .eml attachment and does not see an Accept button. This issue can occur in Outlook on the web when an Exchange mail flow rule is configured to add a disclaimer, signature, header, or footer using the Wrap fallback action.

To resolve this, please ask your Microsoft 365 or Exchange administrator to review the mail flow rules in the Exchange Admin Center:

Navigate to Mail flow > Rules.
Identify any rule that adds an organization-wide disclaimer, signature, header, or footer.
Check whether the rule's fallback action is configured as Wrap.
If so, either:
- Change the fallback action from Wrap to Ignore, or
- Configure an exception so that calendar sharing invitations are not processed by the rule.

For additional details, please refer to Microsoft documentation: Accept button is missing on a calendar from a sharing invitation - Exchange

Once the mail flow rule has been updated, please resend the calendar invitation by following these steps:

Open Outlook on the web and select Calendar.
Right-click the shared calendar and select Sharing and permissions.
Remove the affected recipient from the permission list.
Add the recipient again and assign Can edit permissions.
Select Share to send a new invitation.

Recipients granted Can edit permissions can create, modify, and manage events on the shared calendar.

Note: If the recipient is outside your organization and accesses the calendar through an ICS subscription, the calendar will be read-only, even if Can edit permissions were assigned. To receive edit access, the recipient typically needs to accept the sharing invitation using a Microsoft 365 work or school account, or an Outlook.com account, rather than subscribing to the calendar via ICS.

I hope this information helps. Please let me know if you continue to experience the issue or if you have any additional questions. I will be happy to assist further.

Hi Jose,

Thank you for your update.

The detail that your colleague received the calendar-sharing invitation as an .eml attachment rather than a standard calendar invitation is a helpful clue.

This behavior can occur when an Exchange mail flow rule, such as a disclaimer or signature rule, processes calendar-sharing messages and uses Wrap as the fallback action. When this happens, the original sharing invitation may be converted into an attachment, preventing the recipient from accepting the invitation normally and adding the shared calendar.

I recommend reaching out to your IT administrator and asking them to review any disclaimer or mail flow rules that may be affecting calendar-sharing messages. In particular, they can:

Change the fallback action from Wrap to Ignore, or

Configure an exception so calendar-sharing invitations are excluded from the rule.

Once the rule has been reviewed and adjusted, please remove your colleague from the Test Calendar permissions, re-add them with Can edit permission, and resend the invitation from Outlook on the web.

Outlook on the web supports sharing a secondary calendar with Can edit permissions to users within the same organization. After the invitation is delivered correctly, your colleague should receive a standard sharing request that allows them to add the calendar to their Outlook calendar list.

Best regards.
