Outlook calendar - Error while preparing to send sharing message

Copper Contributor



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.
