I have a script that creates a .fmpsl doc which it then emails.
The person receiving the email they double click on the attachment and their MAC opens Filemaker and bring them directly to the record.
Been working fine for years.
Now, after upgrading to FM16, a few stations get the "Either the host is not available...." error.
They have 75 users and so far only three are having this problem.
They are all on the same version FM and the same OS (sierra)
Any thoughts of what I should look for?
