Question about Outlook Express

I have several devices through which I read email (via POP 3 or IMAP). The messages are downloaded to each device and remain on the server for 60 days - then are deleted by my principal mail client (now Outlook 2016).

Since installing a new W10 machine with Office 2016, I keep getting locked out of my account. The ISP helpdesk were far from helpful, suggesting a client issue. Indeed, the problem seems to occur whenever I boot my W10 machine. Workaround is to log onto webmail to authenticate - then all is well 'till next reboot.

I have reduced email checks on the main 3 devices (that are always on), to 20 mins - to avoid simultaneous login conflicts, but still the problem occurs.

It appears as though there may be a conflict between Windows Mail and Outlook 2016, but I cannot de-install Mail in preference to Outlook.

Any ideas please?

As in the title, for some reason Photo album and Single photo attachment option has been greyed out and must send pictures now as a file attachment.  Any help out there?  Thanks!

e mail problem

Server error 4102      windows live mail error  IDOx8DE00001

Windows Live Mail 2011 & 2012

The program will  not show new messages when the program starts.

Also, I'd like the program to automatically check for new messages every 10 minutes.

It will not do either despite checking the required settings:

File, Options, Mail,

Send and Receive messages at start-up - ticked

Check for new messages every [10] - ticked

The only way to get any new incoming messages is to click on the Home menu button- Send/Receive/specific email acount (Default Account).Then in the bottom right-hand corner it will flash - Checking/authorising etc and assuming there are new inward emails, they will show in the Inbox.

This problem was seen in v2011 running Windows 7 Home Premium.

I upgraded to Windows 10 and v2012 but the problem remains.

I have tried uninstalling Live Mail and reinstalling with no difference.

I have tried an alternative email program such as Mozilla Thunderbird and this problem doesn't happen but I wish to stay with Windows Live Mail.

There is no delay about sending emails - they go into the Outbox for a few moments and automatically go.
