Hi all, I have a client who have been struggling for the last 2 years regarding items within the calender dissappearing. My company already went through various steps to determine the cause of the issue but still have not gotten to any conclusion/ I need to enable Calender logging for a specific user to determine the cause of the issue, however I will need the correct store.ttd file. Could anyone asssist me with this? Regards Shaun

HI Shaun, In this situation you need to open a case with microsoft, I hope you already gone thru all the required stpes to troubleshoot this "store.tdd" file. The store.ttd file is a Microsoft internal evolving utility that is updated frequently to fix issues on a case-by-case basis. Please contact Microsoft for the file.
