I often check my email on my phone and until recently that "read" status is reflected in my webmail browser. Now that isn't getting updated unless I read the email in the webmail browser itself. It's really annoying to find emails I've already read still marked as unread in the browser.
I haven't changed any settings so why has the server behaviour changed?
Re: Email "read" status not being picked up by server
That's what I would expect, but it isn't always happening. Today it was a lot longer than 5 minutes since I had read email on my phone (more like an hour) and refreshing the page didn't make it replicate properly either. It is intermittent, sometimes email read status is correctly updated, sometimes not.
Were any changes made to the device or the email account around the time you noticed the problem?
Is the account setup as IMAP or POP? It sounds like IMAP from the help you've been getting so far, but we just need to be sure
Can you try removing & recreating the account on your device to see if the problem persists
The problem started a day or so before I posted about it last Wednesday. I hadn't made any changes to my phone or the email account, which was set up as IMAP. I've been using IMAP for years but this is the first time this has happened.
I deleted and recreated the account on my phone as you suggested. This seems to have fixed the problem. Read status on the phone is now replicating correctly in webmail again, everything syncs as it should. Thanks for your help.
