more outlook BS !

Hi,

I've been fighting for months with Outlook and my home PC since I foolishly put my works office 365 on the PC with my installed copy of 2021 or 2016.

I have since quit because of that and hey presto now my outlook is just junk.

 

In 2024 I made a copy of my contacts and called them:  shawcontacts.pst   and     wicom contact.pst   and found the old email dated Wed 2024-04-17

but of course since out look IS so stupid I now get:

 

  • OUtlook blocked access to the following potentially unsafe attachments:  shawcontacts.pst,  wicom contact.pst  because of course their files that Microsoft creates and uses should be blocked.....

I tried the reg edit: Level1Remove    and the   .js    trick and no joy ......  am I screwed to get my contacts back?

Cheers'
Dave

    As described by this Slipstick article:
    slipstick[.]com/outlook/block-additional-attachment-types/#Level1Remove

    I have tested by adding a Level1Remove string value of ".pst", restarted Outlook, and it now allows me extract a PST file attachment from an email.

    If you can not get this to work, please describe exactly what steps you used to add the Registry entry.
