GroupWise 2012 sp3 running on Windows 2008r2. Mobility Services 2.1. We upgraded on 4/18/15. We are trying to set this up on his Outlook 2013. Everything works until it downloads 406 emails. Outlook then crashes and restarts. The next time it tries to receive, it crashes and restarts again. He has been running IMAP for years with no problems. Is there a limit on how many emails can be downloaded via Mobility Services?
