Outlook problem

[Glosphil]

In March I took over as chairman of a charity. This included taking over the chairman's email address. For email I use Outlook365 on my HP laptop running Win11 & my Android smartphone. All went well for more than a couple of months and then the troubles started. The chairman's email account held emails going back to July 2021. Last week all the Inbox emails before 29th March disappeared from the laptop & the mail server (Sent was still there). A couple of days later Outlook365 displayed "Synchronising Inbox" for almost 2 hours & the missing emails returned, only to disappear again the next day.

Suddenly today all the emails in the Inbox of Outlook365 were downloaded onto my phone. If I delete an email on my phone then it is also deleted on my laptop & the mail server.

I assume all this is to do with Sync'ing. I don't want any Sync'ing. I want my phone & Office 365 to have no connection, just each to be connected to the mail server.

How do I achieve this?

You can’t have it both ways

They are either connected and synced, or disconnected and not synced!

Not sure what your requirement is here?

The way the app I behaving is common to most email apps I have used

So if two devices are connected to the mail server you are saying they will always affect each other?

That doesn't happen when I use the same phone &. my PC running Win7 & Outlook 2003. Then both are connected to the server (BT mail) but have no affect on each other. They independantly send & receive email. Deleting on the phone does not delete on PC & visa versa.

I still think my current problem could be solved by 'breaking' the sync.

Does the former chairman still have access to the username and password?

That's a good thing to ask. No, he doesn't, password changed.
