Linking to other files in Excel 365 ProPlus

[j3andc]

I am new to office 365 and have recently started having problems when I re-open a file that I have previously linked to. If I open the linked file while the file with the formulas is open, the link gets "broken" and has to be recreated. This is wasted time and I cant afford that. Is anyone else having this problem and how do you get around this.

Thanks in advance for any help

Jim

I found it. It was the "Trust Center". It is treating files across our network as from the Internet.
