Um? Anne Michels that's an old thread, this issue hasnt happened recently and I believe it to be fixed now :)

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!

Two years later this is still an issue with delve.. we have a custom application which has a 'view users profile' link. Intermittently we get this issue and it affects everyone in the org at different times so it's not a reasonable work around to clear cookies on a case by case basis.

Can the service just be reconfigured to have a less aggressive cap on cookie length?
