Change primary email address, now unable to see anything

[null null]

Hi

I've made a major error (& stupidly), I changed the primary email address on my O365 account, everything seem to work ok except OneDrive for Business, I was getting access denied to everything, possibly permissions hadn't changed over? Anyway impatiently I to reverted back to the old email address and now when I login to OneDrive it is appearing as a brand new OneDrive except my recent files are there but when I click on them I receive a 404 File not found error.

Has anyone come across this before? Hope you can help!

Talk to your Office 365 Admin so he can makes owner of your old ODFB and recover the files

My I ask how you changed the primary emailaddress? As far as I know, nothing should change regarding your login unless you change your UPN

Hi Adam

I changed this via the Office 365 admin page, left it for a few hours but couldn't access anything in onedrive, changed it back (probably shouldn't have done that) and now one drive is blank.

I have noticed that if I add a "1" to the personal path, so browse to https://companyname-my.sharepoint.com/personal/newaddress1_co_uk I get an access denied, but can't see where I can amend the permission.

The account I am using is a global admin and it doesn't appear in the sharepoint admin page under user profiles.

under user profiles in sharepoint - can you see your old OneDrive site? Where is the "1" coming from?

Are you using the same login credentials (username) now as before your mail change?
