Unable to send share calendar invitation invite within Outlook 2013

Our Exchange environment is Office 365 (Exchange Online). One of our user is unable to send calendar invite from within Outlook 2013.Error message: "Error while preparing to send share message"

I have done below troubleshooting steps, but all in vain.

1) Ensure no duplicate permission entries.

2) Account setup type - Exchange Account. Recreated outlook profile but same issue.

3) Ran outlook with cleansharing switch.

User able to successfully send share invite via OWA but not within Outlook 2013. Please advise. Thanks

Hi Murtaza_K,

 

To narrow down the issue, please try the following steps and see if there is any improvement:

 

  1. In the Outlook client, navigate to FILE > Office Account > Update Options > Update Now, update the Office suite to the latest version.
  2. Do an Online Repair for the Office programs.
  3. Hold the Windows key + Letter ‘R’ from the keyboard to launch the Run command, then paste “outlook.exe /safe” in the open box to start Outlook in safe mode.
  4. Download the Microsoft Support and Recovery Assistant for Office 365 and see if it helps.

 

If the issue persists, I’d like to collect the following information for investigation:

 

  1. Did the user encounter the issue when he used Share Calendar button to share the calendar? If he select the corresponding calendar and then grant the calendar permission directly by clicking Calendar Permission, can others open the shared calendar from their side? Here are two screenshots for your reference:

 

      2. In the Outlook client, navigate to FILE > Office Account, let us know the detailed version of the affected Outlook.

      3. Does the issue occur to any other users in your organization?

 

Any updates will be appreciated.

 

Best Regards,

Aaron
