Hi

We have a member of staff who has begun working for us who will be working for separate arms of our company. Each arm uses Office 2013 but the installations are slightly different - the company name is different. I have used the setup /admin switch to configure and create two separate installation points for this.

Because this member of staff will need to share content from both arms of the company, is there an easy way to change the company info details without the need to manually change it or without running the relevant setup file each time?

Thanks

Although it's quite an old article, this looks like it *might* still be applicable:

So you could use Domain Group Policy (Preferences)-Registry, to make a change like this.
Or if it's a small number of changes, infrequently, you could connect via network to the machine and edit the registry by hand.
Or run a script.
