I recently had a double whammy with my desktop PC and my Surface tablet both having hard drive failures/issues. Result was that on my Desktop PC I reinstalled Office 2019 and set my Outlook up for my BT Internet E mails. When I logged on for the first time I got all my E mails downloaded from the server with no issues. Good start I thought. I like to also keep a copy on my surface pro 3 so did the same except my license is for Office 2013. I re installed Outlook and set up the account the same as my desktop with all the same settings but I only get a few months E mails downloading to the surface pro. Before the HD issues my surface pro was set up with the Office 2013 package and worked perfectly OK with all my E mails downloaded locally. I have tried deleting and reinstalling but just keep getting the same issue that not all the E mails appear to be synchronising to the tablet. Grateful for any advice on what the issue might be.
My Desktop is running W10 Home V21H1
My Tablet is running W10 Pro 21H1
