Can't sign into Office 365 with any account - only on one iPad

[LowestFormOfLife]

Hi all;

 

Wasn't sure if this should go in the Office thread or iPad, but I think the problem lies with the iPad, so here goes... seems like it should be so simple, but I don't get it - please don't shoot the newbie!

 

I have a user with an O365 account who can't log in (using Word, Excel or PPT) using the apps on her iPad. I can't log in either. But both of us can log in with our accounts on another iPad and on a PC - and also on her iPad using Safari. I can then use (e.g.) PPT Online to create and save and reopen them on other devices. It's only on the apps on her iPad throws back the message "Can't verify subscription - try again later". I have cleared the Office installs and Mobile devices on my O365 admin portal so I don't think it's a licensing/activation issue.

 

So I reckon it's something on the iPad itself. Tried going into Settings - - Reset - Delete Sign-In Credentials for each program. Tried deleting all three apps and redownloading. Restarted iPad after each. No joy. Only background info which may be of note is that I think she may have inadvertently created a personal O365 account using her school email address, the same email as her school O365 account. Whether this is relevant or not, I assume something has got stuck on the iPad apps that is preventing sign-in, but I would've expected this to clear if the apps are deleted and redownloaded. I don't really want to have to advise resetting the iPad unless absolutely necessary!

 

Has anyone come across something similar and/or has any suggestions? If I had hair I'd be tearing it out! Any advice much appreciated. TIA
