One of our user got a subject problem, she tried to share the calendar under Outlook2013 to our colleague but got the subject error.
She use Win10, Outlook 2013 (last updated) with Exchange Online plan 1
I have tried following methods:
- online repair Office 2013 via control panel
- remove add-on item under the Outlook "Add-ins"
- using "Calendar permission" button to grant permission to user
- remove all MS office 365 credential under Credential Manager of Windows 10
Appreciated if someone can help, many thanks.
