This is still an issue for me. It's been happening for years, and is still frustrating.

Across .office.com and portal.office.com, today I had over 16KB of cookies! This is really extreme. Here are just the ones 50 bytes or over:

The rest still add up to over 1000 bytes.

Unfortunately, this has definitely not been resolved!
