When I use the Send Mail script step "via email client" Filemaker opens an email in Outlook then a dialog pops up that says "Server Busy, This action cannot be completed because the other program is busy. Choose 'Switch To' to activate the busy program and correct the problem." The options on the dialog don't actually do anything and both Filemaker and Outlook are locked until the dialog is dealt with. The only solution I have found to get out of this locked state is to use Windows Task Manager to shut Filemaker down. This has happened on multiple different PC's on the same network. We are using Filemaker Server 14.0.4 on a stand alone server with Windows Server 2008. One of the PC's is running Filemaker Pro Advanced 14.0.5 on Windows 10 with Outlook 2010. Another PC is running Filemaker Pro 14.0.5 on Windows 7 with Outlook 2010.
