I mainly do email on a Mac. On the Mac, I have subfolders, and I move messages to the appropriate subfolders. For example, I would move a hotel reservation confirmation email to a subfolder for the trip during which I would stay at the hotel.
I have an iPad, and I would like the moved messages to be in the subfolders on the iPad. By default, they are apparently not copied to a subfolder on the iPad until I navigate to that particular subfolder. Of course, the messages are only copied then if I have a network connection, and I might want to review a message when I do not have a network connection.
Is there some way I can tell the iPad to synchronize all subfolders without navigating to each subfolder? Navigation to the individual subfolder is necessary in each account (iCloud, gmail, and Exchange), so it doesn’t seem to be related to the server. In other words, the subfolders appear in the mailbox list on the iPad, but until I select a particular subfolder, it will not have recently added messages on the iPad. (By recently added, I mean since I last navigated to the subfolder. Some of the messages that just downloaded were six months old.)
Unrelated to the problem I just described (which is by far my main concern), yesterday I tried to view the messages in a particular subfolder. (Of course, that’s why it’s on my mind and why I’m posting this message.) I had a network connection (from a college, and that required a login, if it matters), but the subfolder did not populate. At home and connected to my ISP, I went to the subfolder and it promptly downloaded the messages in that subfolder. What settings should I check to try to figure out why the messages would not download while I was away from my ISP?
In case it matters, it’s an iPad Air 4th generation running iPadOS 14.8. However, the problem existed on an iPad Air2 with multiple versions of iOS and iPadOS. The iPad Air 4th generation has 256 GB with 21 GB used.
Thank you for any help.
