Error message: "You have reached your Zotero File Storage quota. Some files were not uploaded."
I am using a Group Library on Zotero for my job. I have a personal account that is connected to the app on my laptop, but the two are easily separated. When I try to sync the group library of my workplace, I see the following message: "You have reached your Zotero File Storage quota. Some files were not uploaded. Other Zotero data will continue to sync to the server." However, it shows that only a single file was unable to make it, and, for my personal account, I have never needed additional storage nor received such messages. Is it a problem with the storage (that would require my workplace purchasing a bigger storage plan), or should I consider looking into the single document unable to sync? Thank you for any help!!

The file listed is just the file it was trying to upload when it got the quota error. There's nothing special about that document. (There could be if it were, say, a 500 MB video file, but this is just a 1 MB PDF.) The point is just that you're out of space, as you can see if you click "Open Account Settings".
I have to admit that I store all my pdfs in Zotero, as I do not like to work with linked files in the cloud. My cloud storage is my employer's and my Zotero database is (much) larger than only this job. I do not want to lose files when I shift employers. Any solution to this problem?
Otherwise, this error message in almost all cases happens either
a) when you sync with a different account than the one that has the unlimited subscription (double and triple check your username in the Zotero sync pane) -- if that's the case, post here again, don't just unconnect your Zotero
b) when the error comes from syncing a file to a group owned by someone else.
If you are absolutely sure it's neither of those (I'm not sure I recall a case from the last years where it hasn't been), provide a debug ID for a sync attempt that triggers that notice https://www.zotero.org/support/debug_output
