hi,

I have a strange problem with outlook appointments.

When creating an appointment for multiple users the subject shows as blank in everyone's diary except the organiser.

This only happens if the appointment has a room mailbox and it has an attachment in the appointment. If i remove the room mailbox or the attachment the subject appears in all users diaries, but gets removed again if i add them back in.

Any appointment that does not have a room mailbox and an attachment are fine.  

We are running Exchange 2010 SP3 ru8 and Outlook 2010 (fully patched) in online mode.

We get the same thing in Outlook safe mode and OWA. 

any ideas?

Thanks

Hi,

Does this issue happen with other clients?

If an attendee open the appointment message from Inbox, can he see the appointment subject?

By "We get the same thing in Outlook safe mode and OWA", do you mean when the subject still invisible when viewing the appointment from OWA? If this is the case, please try creating such an appointment directly in OWA and then check if the problem continues.

Please let me know the result.

The issue happens to several users, but only when they are booking appointments as a delegate. We only use Outlook 2010 so have not tested with Outlook 2013. I have tried it from several different machines and get the same issue. Same issue in OWA and if I delete outlook or windows profile.

Subject is invisible when viewing in OWA or from any of the users. I have tried creating the appointment in OWA and when in safe mode in Outlook (to eliminate add-ins) but I get the same issue.

It seems to be permissions for the delgates to the meeting room as it only happens when meeting rooms are added into the appointment (and there is an attachment). If i create an appointment on a user directly (e.g. not a delegate) and add other users in everything works, even with attachments.

any appointment that has a missing subject, I can remove the attachment and it will magically come back on all users, but disappears if i add it back in. Its very strange.

Thank you for the update. This forum focus more on Outlook client side issue, since this issue exists in OWA, it's more likely a server side issue. I'd recommend you post a new question to the Exchange server forum to get further assistance:
