Hi Bob,
Does this issue occur to all meeting requests sent by User A, and received by User B?
How about testing by sending the meeting to other users and checking if the issue persists?
What steps you have tried so far for troubleshooting?
To help you better, please provide the detailed error message mentioned in your thread then we can do further research on this. You may share a screenshot via
OneDrive and paste a link here.
Besides, please login to webmail and see if the meeting can be accepted as expected.
Any findings, please post back at ease.
Best regards,
Yuki Sun
