I recently have had a helpdesk request for this situation and I have gone through the forum but have not found any information.
The user is receiving a meeting invitation from a colleague and accepts the meeting. He checks the calendar and the entry is where and when it is supposed to be. He then proceeds to highlight the meeting request, in the inbox, and hits delete. It puts the X by the message and then he hits the refresh button to get rid of the message. When he confirms the deletion, he checks his calendar for that date and then entry is gone.
I have not seen or heard of this before. We have checked his Tools -Preferences to see if there are any options there that stand out but they don’t.
We also tried sending an meeting invite from the problem user to the user who sent the meeting invite and that other user was seeing a problem as well. So it is not just one user but a couple who are experiencing this issue.
Any suggestions or advice would be great. Thanks.
