Honestly, we have no set standards. It's something I think we should be doing but no one has enacted a policy for this. I think this would just be something we should have for legal issues, should they arise. What does everyone else have set as a retention policy?
Secondly, the use of calendar is very important to our higher ups. I've been looking at setting up a Kolab server for email. From what I've read this allows for a calendar add-on. What other options are there for email servers? The whole issue with GAPPS is that there is information on servers that we do not control. And our attorney has advised us to bring all communications back inside our district. Now, we are being forced to do so and insure that no information is located off-site. This rules out Outlook 365 even. Honestly, I feel like this whole thing is being blown out of proportion, but maybe I'm wrong. Judging by Dos-Box telling me that many members are switching back to exchange.
