PROBLEM IDENTIFIED! [<:o)] It has nothing to do with Pegasus! It's Google. Now it's just up to my university's IT to remedy it for me.
Today,
with one short series of steps I found on the web. I successful linked
my Pegasus 4.7 to Yahoo's IMAP server in mere minutes and had full
connectivity - all my Yahoo folders and email appeared and functioned
within Pegasus.
However, I had a maddening labyrinth to go
through to link my personal (not univ.) Gmail to Pegasus with IMAP. You
have to go into your Gmail account, go to Settings, then Forwarding and
POP/IMAP, select IMAP "on", then follow a link at the bottom of that
page to configure the setup, then follow another link to "Other devices"
and finally click to another page to choose to turn "Less Secure Apps"
ON - and THEN Pegasus can access Gmail's IMAP as well as Yahoo's! The
number of steps to do so is absolutely absurd, but it's done now. And it
works fine.
The problem is that my university has partnered
with Google with their IMAP setup, and the U's user-unfriendly Outlook
web interface does not offer this series of steps to select the
necessary IMAP options to access my own university account via Pegasus
as I've done for 15 years. And nobody will be back in IT until January
4th.
But now, at least I know it's not any problem with Pegasus
and simply a new confounding problem created by Google, the ones who
keep making the internet more difficult in the interest of needless
innovation and monopoly. ("Labels" indeed! [^o)] Just give me folders!)
