A calendar was shared with me in Outlook 2007 by a user with the correct permissions. I recently upgraded from Office 2007 to Office 2016. I accidently deleted the shared calendar and was unable to have the user resend the Calendar request to me. I was able to do a search in my deleted items of all Outlook folders and was able to retrieve the e-mail in which the user e-mailed the shared the calendar. I was able to open this calendar up again in Outlook 2016.
My question is when the user tried to send out this calendar prior to me being able to retrieve it, her menu had the share/send button grayed out, in which she was unable to send the calendar to me again or anyone in general. Does anyone know what may cause this? Is there a fix to that will grant the user who owns the calendar rights to share with anyone else, so the user will not have to create a new calendar? I appreciate anyone's feedback.
