Email stopped working

BT Webmail is working now.

This morning BT Webmail was taking a long time to open in Microsoft Edge.

Microsoft Outlook was still able to access Btinternet.

I deleted all my history and reset Microsoft Edge and it is responsive again.

Microsoft Edge is up to date.

Version 140.0.3485.54 (Official build) (64-bit)

I noticed today it now defaults to the setting that works.
