Fair enough. I didn't realize that it wasn't supported. That makes sense,
then.

Did it support push for sub-folders? If not, once again, you're dealing
with a
different situation.
I don't recall, and it's since been uninstalled. However, of my 37 folders,
only 17 are subfolders. The other 20 are top-level, so subfolders is likely
not the issue. This is especially true since I only have Push set up for 3
folders in K-9 anyway.
I should be more specific, my experience with the stock e-mail client for
Android is it only supports PUSH (and maybe sync) on the default Inbox. The
Gmail app uses a proprietary protocol, not IMAP. I believe it's based on IMAP
but I don't have enough information about it to know for certain (which is why
you have to enable IMAP when you want to use something other than the Gmail
client). Full disclosure, I use the Gmail client for Gmail as K-9 for
everything else. Couple of different reasons why which I am not going to get
into here.
I don't know how "SYNC" works, but I don't see a way to limit synching the way
I can limit PUSH. In the folders, I can set the folder class for Sync, but
don't see a setting for "Only Synch 1st Class Folders" like there is for Push.
You absolutely can. You can select the sync class on a particular folder and
you can turn sync on and off. I only sync about one every 24 hours and count
on push for everything else.
Regardless, there are no settings I know of in Outlook which limit IMAP
connections, so I assume it's full throttle. Having said that, this is a
GMail account, and GMail has a max of 15 connections. Since I never saw this
issue with just Outlook, it looks like Outlook functions perfectly well with a
minimal number of simultaneous connections. I do not have insight into
precisely how many it is using, but I don't understand enough about the
mechanisms of IMAP to know why K-9 needs more. I suppose they both could be
using 8-15 connections for 37 folders...?
Desktop clients don't use push, they only do an active sync/check for new
mail. Push is for mobile clients. And push keeps connections open. If you're
only doing push with 3 folders then hitting that maximum seems unlikely. But
it might be some combination of factors.
As I mentioned, I only have PUSH turned on for 3 of the 37 folders on my
phone. To be clear, I have PUSH active for "1st Class" folders only in the
account settings, and only have 3 folders set up as "1st Class" in the
folder's "Folder push class" setting.
I'd double check those settings just to be sure.
I wish I could help more, all I can really make is suggestions.
