Determine the scope
Record the exact path and error. Check whether colleagues can open the same share and whether you can reach other company resources. Remote users may need an approved VPN connection. A missing drive mapping is not necessarily a deleted folder.
Check identity and permissions
The active account, group memberships and both share and file permissions can affect access. Ask the administrator to confirm the intended role. Do not solve a permissions problem by granting everyone full control or by sharing another person's credentials.
Verify the needed operation
Being able to list a folder does not prove permission to edit its contents. Test the authorised task with a harmless sample and preserve existing files. Document any permission change and its owner so access remains manageable.
Sources and further reading
Options vary by product version, subscription and organisation policy. Refer to the vendor documentation before making changes.
