Windows 10: Outlook 2019 - suddenly lost huge number of emails under "Deleted"

In real terms it does not matter much (or at all) but I've suddenly noticed that I've lost over a year's worth of emails under "Deleted". The resource now goes back only as far as SUN-11-APR-2021 whereas previously as far as the date of opening the account being FRI-08-NOV-2019. Of course: I cannot remember when I last looked - but very recent seismic events include (i) Windows 10 versioning from 20H2 to 21H1; (ii) an associated and almost simultaneous update to Office 2019 that took about half an hour (or more - I went away and came back); and (iii) building the same account on a new phone - but I've done this countless times with no similar accident occurring. And, yes, I have already used the "Recover Deleted Items from Server" button in Outlook. Still getting just the most recent 6 or 7 weeks' worth of items instead of 18 months'. I have not requested any Archiving and nothing is showing up under Archive. Just really tantalising: in one sense of zero importance; in another, of massive importance - how can one lose a massive slice of email history? We can all imagine circumstances where Deleted emails would provide essential scrutiny. Any ideas? Thank you! Windows 10 Pro 21H1 (latest update) Office 2019 (latest update)

Outlook Email Random Letters & Numbers

I put Office 365 on my mother's computer under my 365 Home license. She's using outlook.com as her email and Outlook as her email client on her computer. Outlook wasn't syncing her email I think due to Microsoft switching to Exchange and deleting the account and starting over was supposed to be the fix.

Anyway I deleted her account but didn't pay attention to the warning I needed to back something up... maybe not smart. I created a new profile entering her name Pat C and email I'll call L: [email protected].

Her new profile syncs plus sends and receives email just fine... but something's weird going on. Inside of Outlook it lists her email address as gobbledygook it's something like outlook.37ej39.07d.outlook.com instead of L: [email protected]. I've already deleted the profile but I believe the profile itself listed it as L: [email protected] but if you looked at the Properties of the account it listed it as outlook.37ej39.07d.outlook.com. The gobbledygook numbers & letters aren't exactly as they were listed but you get the picture.

I tried creating new Profiles plus doing an Office Repair but I always get the same random number & letters for her email. Nor do I ever see this gobbledygook during the setup process... only after it's finished.

Anyway to fix her email when using Outlook... her email is fine outside of Outlook?
