Room Mailbox repeating email "Accepted through " to meeting organizer

Question

Monday, July 22, 2019 8:01 PM

The tenant has an O365 Exchange room mailbox that sends an email every day to the meeting organizer for a recurring meeting. The issue occurs across multiple rooms, multiple users/devices, and multiple meetings.

The email has the subject "Accepted through <date>: <UserName>" where date is equal to the current Date plus 3 years, minus 16 days.(If the date today is 7/22/2019, the subject in the email would be 'Accepted through 7/6/2022: Tyler')

The user has O365 Outlook 2016 and does not use iPhone. 

I am including the configuration details below. I reviewed these as well and did not identify any issues.

Hi Tyler,

Please check if there are any other meetings or recurring meetings that may be in conflict with any meeting in this series.

AllowConflicts                      : False
ConflictPercentageAllowed           : 0
MaximumConflictInstances            : 0

It seems no booking conflicts would be allowed for single or recurring meetings, which may result in some unexpected behaviors.

Regards,

Manu Meng

I checked the calendar and did not find any conflicting meetings. As a test, I set the AllowConflicts to true and found today the emails are still being sent by the rooms. 

Command I ran: 

Set-CalendarProcessing $mx -AllowConflicts $true -ConflictPercentageAllowed 75 -MaximumConflictInstances 3

OK, got it.

>> The tenant has an O365 Exchange room mailbox 
>> The issue occurs across multiple rooms

So if just one room mailbox or multiple room mailboxes encounter this issue?

Did you set a recurring meeting in OWA? What's the result? 

Besides, could the issue be reproduced on the non-recurring meetings?

To better resolve the issue, I suggest you test in OWA, and if possible, remove the account from the mobile device to verify if it is related to mobile devices.

Was this ever resolved? I'm having the same issue. We just enforced using meeting rooms throughout our organization. I have a few recurring meetings and I get an email every night approving each meeting. Shouldn't it only approve it once and not nightly? There are no conflicts. Using Microsoft Office 365 Business.
