Here is the statement from the Microsoft OneDrive product group (Redmond USA) about the OneDrive Personal problem:
***This is related to a backend migration we are doing and unfortunately, we don’t fully support syncing shared folders in the case where one user has migrated and the other has not. We’re doing everything possible to accelerate things so that it can be resolved as soon as possible for users of the feature. When the accounts are migrated, there is automated logic that makes them go back to a syncing folder within several days.***I have heard, that shared Folder issue is gone.
The best thing is: WAIT and do nothing
Mr. Hans, thank you for replying in this topic...as we know that you are important person in the MS OneDrive Division (or related with them somehow) :)
Can we ask you for a favor?. Please tell the OneDrive backend team, that this is not a way how it should be done in matter of communication or migration.
If they know that it will break something, why dev team did not make any statement about it? Like answer to this topic with explanation or the ETA of the migration. They broke things and they knew that it will take some time to migrate and they don't say anything. People are struggling on their own, wasting time, Support do not know nothing about it to share the explanation about it. They say: "did you try to turn it off and on again?".
When the shitstorm happen, people were so desperate that they try to contact someone in social media or other platforms to bump the problem higher. Shitstorm happen and then MS put some sentence on support page: "that they are aware of that". After months!!
Backend team should inform support that it could be reports about this, so please inform users that they have to wait.
Backend team knew that it will take time, at least 3 months, because I was hit by this 3 months ago. So what backend team was expecting? That people will not notice? Let's be strait: backend team f*cked up this. Please be aware of time spent by people, frustration, research because nobody from dev team was not willing to inform users about it, or make migration in better way.
I am very grateful for your engagement in this, but i have a personal "request" for you... when you will someday in a meeting with them, please tell them that they totally screw things up. Next time, they should track migration process to users who share something and to users that do not share. Migrate accounts connected with each other by sharing in the first place. Inform support about it, inform about ETA.
Again, thank you Hans.
