Using older versions of Outlook for Mac in business environments
Hello AdamRiceAAAAAAAAA,
Thanks for your post in Microsoft community. Regarding your issue, does this issue occurs all the time or just one time occurs?
To narrow down this issue, we request you to kindly run message trace report for that meeting invitation email and accept invitation email. To run message trace report, you need to contact your O365 admin and ask him to follow the below steps.
- To do so: Login with Global Admin account in O365à Exchange admin center -> Mail Flow ->Message trace -> add the sender, recipient email is and select the date range (once message trace report open, select the trace, open it and share the detail information)
Kindly run two message trace report:
- First for meeting invitation email > select sender and select date range (once report generated, check the reports with meeting subject line and check if it delivered to other two members of the group) > kindly collect screenshot for your generated report, open such individual entry , capture screenshot and share with us.
- Second is for meeting acceptance email > select sender and select date range and based on subject line collect all the information.
Please provide above all requested information via the Private Message, so we can help to check further.
Also kindly check if is there any forwarding rule is set up one that group member (whose acceptance email delivered to other group of members)
Thanks and regards,
Ankita Vaidya
