In Outlook 365, until recently if I right clicked on an attachment, it would sometimes have the option to open the file location and, from there, I could see a list of attachments. Then I could delete unneeded (e.g. .ics files) or large attachments (which I would do to keep the folder smaller). But I can't find that option anymore and therefore can't find that folder. (Why did that option disappear?) I looked in Documents, which some threads elsewhere seem to point to, and Downloads, which had, I think, worked previously. I may be misrecalling that last part.
By searching for .ics files, I found a folder C:\users\myname\AppData\Local\Packages\microsoft.windows.communicationsapps_[long code here]\LocalState\Files\S)\4\Attachments. But it had files only from early Nov 2021 to early Dec 2021. Strange.
I can't/don't want to do it by deleting attachments from each email, some of which have been deleted or stored. That would mean I'd have to do it while I can view the email. Can someone point me to the right folder? And please don't tell me they're inaccessibly stored in an ost or pst file!
(Outlook is really onerous and not user friendly in this respect. My old email app simply stored attachments in a readily accessible folder.)
Thank you and sorry to complain.
