I am using Outlook 2010 (on Exchange with Windows XP) but do NOT have access to my boss's inbox - only to her calendar, which is why my question is in the Outlook section and not Exchange. We have added me as a delegate with the highest level of permission: Editor. I am aware that this can be done via Share Calendar or Calendar Permissions and I did it via the latter.

When I create meetings in my boss's calendar, it sends them from me, showing me as the Organizer and her as an attendee. I have searched the MS Office Community forum extensively and keep seeing that this is because I do NOT have delegate permissions for her mailbox/Exchange account. Yet a coworker said she was able to send an invite on behalf of her boss WITHOUT having access to his inbox.

Is this possible? Thanks in advance!

Try the below steps:

1. Open your managers calendar.

2. On the Home tab, in the New group, click New Meeting.

3. Enter the attendees, subject, location, and start and end times as you ordinarily do.

If this doesn't work you'll need to request "Send on Behalf" permissions for your managers mailbox with your service desk.

Hi,

Have you double-checked if the delegate permission was granted successfully under File > Account Settings > Delegate Access?

We can also try deleting the boss's calendar in your Outlook and then open it again to see if it helps.

In addition, do you or your boss syncs emails on a mobile device? I heard that syncing emails on a mobile device may cause such issue, if this is the case, we may try to disable the synchronization on the device and then test the issue again.

Please let me know the result.
