I am receiving error (0x80070057-00000000-00000000) when sending meeting requests.
I get the error regardless of who is included (internal or external for my Exchange server).
I have looked for rogue macro's and any malfunctioning add-ins but have had no luck.
There are no macro's installed. The one I expected to see (ShowAppointmentCreator) is not even there.
If I start Outlook in safe mode and send the meeting request it goes through without any trouble.
Aside from the typical user malfunctions all other functionality seems to be working just fine.
Does anyone have any further suggestions?
Thanks in advance!!!!
