We are using Office365 hosted Exchange (Rackspace) with Outlook 2016 desktop clients.
Several of our top executives and key employees have very large OST files which affect the performance of the Outlook client. At the same time, they do not want to delete mail and want to maintain accessibility to all of their messages. I have had (as most) bad experiences with PST archive files becoming corrupt and do not want to utilize them as a solution.
Does anyone have a solution for maintaining access while reducing the size of the OST file sizes. Are their recommended 3rd party apps that integrate fully with Outlook? What about apps that automatically store attached files in the file system rather than as part of the OST file?
Any help would be appreciated.
