It seems portal.microsoftonline.com is down, this may affect OnedriveMapper users, some tenants seem to get redirected during the logon process to portal.microsoftonline.com, but many also don’t. If you’re affected, open a ticket with Microsoft.
OnedriveMapper will show this in the log: | ERROR | Error detected while following redirect, check the FAQ for help
Update: it seems only ADFS / federated tenants are affected.
Update: the RPT update command seems to have fixed the issue for most of those affected.
Here is the link to O365 tweet about the issue – https://twitter.com/Office365Status/status/979719934707040256
Looks like MS is restoring the site now.
Same issue here. Have a Sev A case open with MS now. Will let you know if we find anything.
If someone with ADFS could test this out: https://support.microsoft.com/nl-nl/help/2647048/how-to-update-or-repair-the-settings-of-a-federated-domain-in-office-3
I’m curious if that’ll help
It just started working for me out of the blue. We didn’t change anything.
I got a reply to my ticket with Microsoft stating that portal.microsoftonline.com has been decommissioned. Seems like a good reason for it to be down.
