I can not receive or send email because One drive is full

YES! I agree!

Did you empty out One Drive? I emptied mine out saving whatever I wanted to my hard drive, and I stopped One Drive from synching. Also, you have to clean out your folders on Outlook. If there is anything you need to save, create another folder and put it there, and also send a copy to another email program like Yahoo Mail, AOL, etc. for safe keeping. You don't know if Microsoft is going to do this to you again. Or you can pay the monthly usage fee but that is no guarantee you'll get all the mail you didn't receive while you were essentially locked out of your account.

You will start cussing Google when you hit your 15GB shared storage limit:

Every Google Account comes with 15 GB of storage that’s shared across Google Drive, Gmail, and Google Photos*.*

I believe the difference is Google only has 1 storage limit (15 GB) while Microsoft has 2 (5 GB Microsoft storage and 15 GB Email storage). The biggest and stupidest problem is Microsoft counts email attachments towards the lesser 5 GB limit.

My solution is to NOT store anything in the cloud except email.

I tried to send an email and it said I couldn't as my one drive is full, yet I have 15G of email space?

My question is why is my one drive data even connected to my emails? I then unlinked my one drive from my email, no difference.

Now, here is the real kicker, I deleted at least 1G off of my one drive, plus cleaned up my emails and it DID NOT MAKE A DENT! Isn't that strange??? or is it they want you to pay for more storage..... I say F$%k that! I Switched to Gmail.

Email is supposed to be free and the fact that Microsoft, a billion dollar company wants to charge for emails, is actually mind boggling. I understand smaller companies....but a BILLION DOLLAR company....no you can p%ss off with that.

You have to clean up Onedrive. Go there and remove, either by deleting or moving the files to your folders on your computer, to free up space. In my email account, I deleted the majority of emails, emptied most folders, and always keep deleted and junk folders empty. I also turned off One Drive, so it doesn't save every single thing on my computer. This seems to have done the trick.
