Outlook 2013 + Gmail leads to many messages in drafts even after it is sent
When Outlook connects to Gmail via IMAP, Gmail instructs Outlook where it wants it's drafts stored. But because Outlook handles drafts differently to what Gmail expects (i.e. local handling rather than IMAP-friendly), draft copies can remain on the server even once the email is sent.
You can resolve this by having Outlook use a local drafts folder on the computer that Outlook is installed on, rather than the Gmail drafts folder.
Right-click on a folder within the IMAP account you are using. Select "IMAP Folders...". Select the "Subscribed" tab and click "Query".
In the list of results, select the Drafts folder and click "Unsubscribe".
You should see the "Drafts" folder in Outlook replaced with a folder labelled "Drafts (This computer only)"
Note that (obviously) this will mean that drafts on that computer are now no longer synched up to Gmail, so you won't be able to access and complete those drafts via the web interface or from another computer.
Since I cannot comment due to low reputation I will post here.
I tried the first accepted solution above and got an error: "Cannot unsubscribe from folder. '[GMail]/Drafts' is a special folder and cannot be unsubscribed from in Outlook."
As an alternative I went to GMail via the web interface. I then went to setting (button on top right of message list) - then to the Labels tab. Uncheck the drafts folder "Show In IMAP" option. This is the same as unsubscribing from the folder via Outlook.
This fixed the issue for me.
I got resolution for the files not being able to be deleted from the DRAFTS folder. I have a one-year Microsoft Assure plan so I just talked with Microsoft support on this issue. I had already looked and/or tried different "fixes" for this Outlook 2013 IMAP DRAFTS folder issue from internet search results (included the "fixes" post on this site) but without success.
My situation is that I just moved from Windows Vista/Outlook2007 to Windows 8.1/Outlook2013. I started having files remain in the DRAFTS folder after after sending the email for which the file was a draft. I had the same problem if I moved the draft to other folders or even after trying to delete the draft out right. In each case, copies would show up in the DELETED or other folders but the original would remain in the DRAFTS folder. I did not have this issue when I was using Windows Vista and Outlook 2007.
I was a little skeptical that the Microsoft fix would work and concerned that I might lose some email in the process. However, it did work just fine and my email files are fine.
The answer from Microsoft for my particular issue that I mentioned above was to:
- Open "Account Settings"
- Highlight the IMAP account you're having problems with
- Choose "Change" on that menu (opens the "Change Account" window). Everything on this screen should be okay
- Click on "More settings..." (it opens the "Internet Email Settings" window)
- Go to the the "Advanced" tab
- Go to the "Folders" section of the window
- In the field following "Root folder path"...type in the word "inbox"
- Choose "OK" (closes the "Internet Email Settings" window)
- Click "Next" in the "Change Account" window (opens the "Test Account Settings" window and run a test)
- Close the the "Test Account Settings" window
- Click "Finish"
- Close the "Account Settings" window
- Close and reopen Outlook.
I suggest closing Outlook in step 13 because in our first test to see if it worked the files in the DRAFTS folder did not immediately go away (even accounting for the IMAP standard sync delay) and also after pressing "Send/Receive" email. So, we closed Outlook, reopened it, and the DRAFTS folder was empthy. I then did a few more tests saving drafts, sending email from drafts and deleting drafts and the tests all worked fine. My DRAFTS folder was empty when it was supposed to be and had contents when it should. As an additional note, I have subsequently save some emails to DRAFTS and so far they are persisting in DRAFTS until I reopen and send them or or until I specifically delete them from DRAFTS.
Try using Google Apps Sync instead. I started using that instead of IMAP and it works great. https://tools.google.com/dlpage/gappssync
