Unable to clear flags in Mail using Exchange 2010

I need to take my words back. The problem appeared again after just a few days 😟

Anyone is developer who got chance to review 10.8 Beta version now and can help to verify if the issue was resolved in next version?

I already give up Apple will fix this issue in 10.7.x cycle and switch back to use Outlook 2011 then.

In 10.7.3 the problem was resolved in my case. I'm connecting to MS Exchange via EWS.

If you still have an issue with flags failing to clear and you're on 10.7.3, it'll be interesting to see if 10.8 makes behaves any differently.

I have been using the second Preview of 10.8. Mail and Exchange work fine now. Flags removed on my iPhone, are removed on my Mac and vice versa. I have yet to notice unflagged items being reflagged.

However the same behavior does not apply to my Google Account. Mail flags all incoming mail. Flags should be applied to Mail as well as other iOS devices. Result: NADA

If I flag an item in my google account on iOS Devices, it does not update in Mail. Same behavior viceversa. Very Hard to keep track of stuff.

10.7.4 is released today. Anyone alreayd installed it and check if the flag issue was resolved already?

Any news here? This changing flags issue is killing me.

Having this problem as well with OSX Lion on the new MacBook Pro Retina. The only solution seems to be "unflag" on my iPhone. Tried everything to clear the flag through Mail but nothing works. Ugg. Another bug?

I am not having this problem after upgrade to Mountain Lion, deleting and re-creating Exchange account. Please, check if this helps to anyone else.

I have scratched my head for too long on this issue! Yet, after reading the several pages of tricks/workarounds, I realized that I may have flagged messages that I moved to "On My Mac" that are no longer in my "Inbox". After about 20 minutes of checking each folder, "Selecting All" and then unflagging the group of messages, I no longer have phantom flagged emails.

I do not know anything about Exchange, so I do not know if this will relieve all grief, but I wanted to share what I dicovered.

Running Mac OSX 10.9.2 and Mail 7.2

Just in case anyone happens across this thread, even if they aren't using an Exchange account...

I have had an empty Flagged folder in Mail for quite a few months now. The only active accounts are a personal one (IMAP) and iCloud. My Google account is disabled.

I'd isolated the flagging issue, showing 8 flagged messages when there are none, to my personal IMAP account. Logging into the webmail account and going through each folder and conducting searches revealed that there were no flagged messages as far as the server was concerned. Definitely a local issue. Also, iOS devices showed no flagged messages either.

I tried editing the plist for flagged messages, but it would revert back to 8 after relaunching Mail.

I was trying a few more things today when I chose Rebuild under the Mailbox menu item and...it cleared! And it has stayed clear after closing and reopening Mail.

Not sure if I'd tried that before (or even noticed the option), but it looks to be resolved now. So even if you're not using an Exchange account (which, at one time, I was in addition to the others), this may solve the main issue of displaying Flagged email when there is none.

Hope this helps.
