Only some users can see all the archived company data, how do I allow other users to see them?

SUGGESTED

We have about 30 archived companies going all the way back to 2013 and only three users are able to actually see the archived companies.

I looked at this article on how to map a network drive and can confirm that all users have the necessary folder for them to be able to see the archives, but still have had no luck.

I also looked into changing where the backups were stored back to their original source and noticed that I have two MB7 folders from times when the backup source was different.

How do I fix this?
