This is on a dell PC that had run out of disk space. I used EaseUS Partition Master to grab some of the "D" partition, allocated it to another letter and it's now used for photos, approx 15GB. All good.

When I open outlook I get the message "Cannot open microsoft outlook" this is a relatives PC so I can't be 100% sure it was all working ok originallly. I have tried outllook.exe /resetnavpane as well as uninstall\reinstall.

Although the account they use is shown to be an admin account, when I change the settings to show hidden files (to check location of the .pst) this has no effect. I have to boot to safe mode and use the built in Administrator account to do this. Conicidence or a sign of something more sinister?

This can't be linked to changing the disk partition can it? everything is installed locally in C:\ using default paths and the only files in D:\ look like Dell restore folders. I had read the hidden files problem was a virus but Mcafee is installed and uptodate and shows no problems and Malware anti malwarebytes also scans and shows all clear.

Apologies for the long post, any help much appreciated.
