+ 0 Votes One Approach to Outlook Synchronizing Problem ExNavy 4 years ago This problem "poped" up recently as it has a few times in the past. I am working out of a home office using Vista with Office 2007 and getting e-mail from my ISP through POP. I have a large number of active folders that are yet archived. Having read yards of responses on this site, I concluded that there can be many reasons for this symptom and it is best to check out some of the simpler options first. It was also a reminder to do some periodic e-mail houskeeping.I have an e-subscription to a local newspaper which comes into my webmail inbox every day. Outlook picks it up, and bacause of rules I have set, moves it into a designated Newspaper Folder and marks it as read. Truth is, I really don't need numerous copies since every one of them leads back to the newspaper's website where I can use my password to get into back issues. In any case, through neglect, this folder was chock full of emails all bearing the same sender and subject, one for almost every day of the year. Somehow, when Outlook downloaded a bunch of e-mails, including some spam which went into Junk Mail, it took in a copy of the newspaper e-mail but did not remove it from my webmail inbox. Later on when I was troubleshooting and checked both locations sepatately, I could see the 2 Jan 2010 e-newspaper in the Outlook Newspaper Folder, in with the many older ones, and the same 2 Jan 2010 e-newspaper in my webmail inbox. In this situation, each time Outlook checked for e-mail, either on schedule or by clicking send/receive it would bring in all e-mails that were in my webmail inbox except this 2 Jan 2010 e-newspaper and then get hung up until it timed-out. During this, the little white square would appear and by moving the cursor it would give me the dreaded "synchronozing folders", as if I didn't know.OK, and with hints from threads above, I did three things: 1. I deleted over a hundred back issues of the e-newsletter and kept only a couple of current ones. 2. I went through some of my other folders where my rules had stored other similar routine e-mails, some marked as read, some not; I marked them all as read and deleted a large nummber of redundant ones. 3. I deleted the offending e-mail directly in my webmail inbox and made sure it was clean.Outlook is now doing fine. While I think the 3rd action was the immediate fix, I also think that the 1st and 2nd housekeeping actions are pert of keeping the affliction from returning. Cheers, + 0 Votes Another possible issue jgmclaughlin 4 years ago I noticed that Outlook has three search folders in the Personal folders- Follow Up, Large Mail and Unread Mail. The Large Mail and Unread Mail folders were chock full of emails that perhaps Outlook syncs up with Deleted mail???I tried to delete the folders, but they keep coming back upon reboot. I right clicked on each, and there are customizations available.My Large Mail folder was set for 100 KB and it was checking all Personal Folders. I reset the criteria to only look in the Drafts folder and reset the file size to 10,000 KB. Unread Mail now only checks the Drafts folder.This seems to help. Any thoughts on this? + 0 Votes Stop Synchronizing tauan 3 years ago As someone already said in posts above it will work when you turn off CHACHE EXCHANGE MODEGood luck! + 0 Votes Syncronizing Folders Frustration Jay 3 years ago Quite frustrated with this annoyance as well, apparently some double negative logic is required. Firstly, check "Work Off-Line" under the File menu. Secondly, switch to manually sending and receiving mail. Considering that Outlook is designed for large corporate environments and assumes Exchange Server, configuring Outlook this way apparently sets "Syncronize Folders=Not" or something simular. One nows sees the Off-Line icon in the Task Tray which looks like an error or problem but is not. For me, the manual mode (as if one were mobile) is what I prefer regardless which apparently tells the system not to even try to syncronize what could be a massive message store. + 0 Votes Stop Outlook Synchronizing Folders john.teng59 2 years ago After many moons of fruitless searching and trying all different permutations of suggested fixes, none of which actually worked for me (mine is exchange server account), i can finally now confirm that turning off the cache exchange mode as suggested previously by someone on this forum worked for me. After apply the change, I have not seen the annoying double folders icon for the pass 1 hour. And more importantly, it does not hang up and slow down my ancient laptop! So, I'm cautiously optimistic that this is the one...true fix, at least for me case! Thanks very much for the long sought after fix.
