Among other things this document points out, that it is technically not supported to store Outlook PST- or certain database files (*.slm;*.ldb;*.mdw;*.mde;*.db?) on your personal home drive. Therefore please remove any data of this kind as soon as possible. Starting on Monday 20th July 2015 it won’t be possible to either create new files of this kind or update existing content. Existing files won’t be deleted, but major issues using them have to be expected.
Furthermore we urgently want to draw your attention to all other points mentioned in the guideline once again – especially regarding the maximum recommended size of your personal home drive - which is 2 GB at the moment. We are going to do an anonymized analysis of the utilization of the home drives in the near future and take action in case of consistent non-compliance. Thank you for your cooperation.
