I have read here, on various threads regarding problems with people's
MDE accounts, that deactivating them on the website actually doesn't really do anything from the back end, and they are still treated the same as active ones. meaning if you have a problem from too many and too much info, deactivating them isn't enough and Disney IT has to actually go into your account and remove them. This is all from various threads here, not personal experience, so i can't be sure. I know I probably have 30 on my account, and my family members have many as well, and we always have trouble with MDE, seeing my MBs and cards, customizing MBs, and using the ones I have as active in the account on our room door the CL elevator, the resort entrance, etc. I only keep 4-5 listed as active, the rest show inactive, but they still seem to bog everything down when we try to trouble shoot these problems either over the phone or in person while on vacation.
