Steps to reproduce

Over a period of a few weeks, my Edge browser, running on a fully patched Windows 10 Surface Pro 4 system will no longer perform certain functions within Office 365 like working with user account details. The UI won’t respond properly. If I persist in using it in this situation it will eventually refuse to connect and responds with some foolish error message about the header being too long even when the URI is nothing but portal.office.com.

The problem can be fixed by clearing the browser history. I’ve gone through this experience multiple times and it occurs with both normal Edge and private browser windows. The problem does not occur with Chrome.

If occasion permits, I’ll capture the error message when it next occurs; the browser is beginning to act that way again, but I usually just switch to Chrome to sidestep the issue. The problem ONLY occurs when I’m trying to perform interactions with the Office 365 admin portal.

My guess is that the Azure portal is caching some type of information that isn’t being managed or cleared properly.

Good luck in running this one down.

    • Hi Bill,

      Thank you for the submission.  I appreciate the offer to help.  If you are able to capture the error message, please add it to this submission.  Also, if possible launch the Edge debugger and check for console errors as well.

      That would help us running this down.  If you are up for a challenge, there are good number of windows debugging tools that are quite fun to use.  E.g. ProcDump and other Sysinternals utilities.

    • Hi Bill,

      With the recent Creator’s update, many bugs and performance issues have been resolved.  Can you try to repro this issue with Edge in the Creator’s update?
