Why is my Outlook ToDoist not working?
I closed my Outlook, installed todoist, and reopened Outlook but I didn't have a new ToDoist sidebar. What else do I need to do in order to see it?
Asked by Lehar Kanodia on Jun 03, 2011 - 09:20
please try installing ToDoist for Outlook again, it will most likely ask you to install Microsoft .NET Framework 4 and Microsoft Visual Studio 2010 Tools for Office Runtime, if it won't you can download both from the Microsoft Site:
.NET Framework 4:
Visual Studio 2010 Tools:
After installing these try to install ToDoist again.
If this doesn't work, please tell me: which operating system you're using? Which Outlook version you're using?

I have both .NET Framework 4 as well as Visual Studio 2010 Tools. Before posting here I uninstalled ToDoist and reinstalled it (it didn't ask me to install either of those applications either of those times).
I am using Windows 7 and Outlook 2007.
1. Open Outlook.
2. Go to the "Tools" menu and choose "Trust center".
3. Select the "Add-ins" tab.
If nothing else went wrong during the installation, you should see Todoist listed there as an inactive add-in.
On the bottom of this window choose "COM Add-ins", click "Go" and check "Todoist".
If Todoist isn't there, try installing it from this window (go to COM Add-ins -> Go, choose "Add" and select the Todoist installer.

That worked, thanks!

These steps (a bit different in Outlook 2010) worked for me, too. Sort of. Now every time I start up Outlook I have to repeat these steps and complete the todoist log in again.
Any ideas why todoist won't stay 'on' in Outlook between sessions?

I am having the same issues as above. Uninstalled Todoist, installed .Net and Visual Studio 2010 Tools, and then re-installed Todoist.
Every tenth time, if I am lucky, the add-in works. I am running Win7 with Office 2010. I have followed all of the suggestions noted above and am in technical support but that doesn't seem to be helping much ;-)
I'm sorry you're experiencing this issue :(
There are some known issues with this add-in and we're already working on fixing it. We will inform you once a new one has been released.
Again, sorry for any inconvenience it might have caused you.

I am using outlook 2010-windows Vista, I did all that you have suggested, but still is not working, please let me what I have to do?
please tell me exactly what isn't working.
Is Todoist listed in Outlook's Trust Center?
Does the installation fail at some point? If so, what error message do you see?
Can you log in to the Outlook Todoist add-in (assuming it is already installed)?
At which point exactly do you experience any issues?

Hi, I've tried all the methods above and have only seen todoist launch once.
I've tried to install from the COM Add-Ins panel and I get the following: " Todoist_For_Microsoft_Outlook.exe is not a valid Office Add-in."
Win7 64bit; Outlook 2010
do you remember what exactly did you do as the Todoist add-in launched?
If not, please try the following:
1. Remove Todoist from Outlook (Tools -> Trust center -> Add-ins -> COM panel).
2. Go to the control panel -> Add/remove programs, look for "Outlook Todoist" and delete it from there.
3. Download the latest Todoist for Outlook add-in.
4. Make sure you have both - .NET Framework 4 and Visual Studio 2010 Tools installed.
5. Close Outlook.
6. Install Todoist for Outlook using the Installer (NOT adding it from Outlook).
7. If Todoist doesn't appear in Outlook, go to the COM panel again and activate it.
8. If it deactivates next time you open Outlook, try disabling User Account Control (set it to "never notify") in the Control Panel.
If none of this works, please let me know at which point you'll get some errors or if it works just once, as before, when does it work?
are you trying to activate it directly from the Add-in tab? If so, on the bottom of this window choose "COM Add-ins", click "Go" and check "Todoist" from there.
In order to prevent the Todoist add-in from getting disabled try disabling User Account Control (set it to "never notify") in the Control Panel.

Hi, I've tried disabling uac and it still doesn't work.
It still doesn't load. When I go to the Add-in tab, the "Todoist" item appears at the bottom of the window. I have tried, as suggested, to choose "COM Add-ins", click "Go" and check "Todoist", however, it still remains "inactive" and does not load.
I have also tried disabling UAC but it still does not work.
thanks in advance

I found the problem and solution:
Here's the problem:
Access to the path 'c:\Program Files (x86)\Microsoft Office\Office14\OutlookTodoist\logs' is denied.
************** Exception Text **************
System.UnauthorizedAccessException: Access to the path 'c:\Program Files (x86)\Microsoft Office\Office14\OutlookTodoist\logs' is denied.
Solution: I created the folders \OutlookTodoist\logs launched outlook and everything works now.
thank you very much for this info. Could you please clarify at which point you've go this error message?
please try doing what Chris suggested - create 2 folders: "OutlookTodoist" and "logs" (inside "OutlookTodoist") within "c:\Program Files (x86)\Microsoft Office\Office14\" (or wherever you've installed Office) and let me know if it works.
Of course this can't be a permanent solution for this issue, but it would greatly help us in fixing the bug in another update of the Outlook plugin.
Thank you in advance for your cooperation.

I found this on the google to troubleshoot the issue:
Okay, do the following:
1. Verify that the add-in is not disabled in the registry (I presume you install it to HKCU)
The LoadBehavior key should be 3. If it is anything else, change it to 3.
2. Start a cmd prompt.
3. type: set VSTO_SUPPRESSDISPLAYALERTS=0
4. Launch Outlook from the command line shell (so that the environment variable is set).
5. During startup, you should get a UI box that pops up with some debug info about why it is failing to load.
we have released a new version of the "Todoist for Outlook" add-in.
Please remove your current Outlook add-in by accessing the Control Panel -> Add/Remove Programs and deleting "OutlookTodoist", download the new application from:
and install it.
If you still experience any issues with the new version, please let us know.

Does todoist work with Outlook 2003. I found the com add ins section, but the add in is not there. Where does the installer put the add in?
Thomas Worbech on Apr 08, 2013 - 14:28
I am having the same issue as the one described above and I have tried all the suggested solutions. When I enter the COM Add-Ins I see the following for OutlookTodoist under Load Behavior:
"Not Loaded. A runtime error occured during the loading of the COM Add-in."
I'm running Win7, 64 bit and Office 2010.
Any good suggestions?
Thomas Worbech on Apr 08, 2013 - 14:41
Thanks David! Do you know when it will be released yet?

I have done all of the things said above.
1. Uninstalled Todoist plugin
2. Installed .Net and Visual Studio 2010
3. Installed latest Todoist plugin
4. UAC set to "never notify"
5. Add in checkbox is checked
It still doesn't load. When I go to Manage Com-Addins screen then it says "Unloaded". After I check the checkbox and press OK nothing happens. I restart the outlook and the checkbox is unchecked automatically. Some times my outlook also hangs after I check the checkbox in add-in screen.

Win 7 Enterprise 32 bit
Please tell me:
- Did the plugin ask you to send an error report to us? If it did, please send it.
- Can you find the logs from our plugin and send them to email@example.com ? They are located either in
I just installed a version of Todoist for Outlook that I downloaded from the web. After crashing the first time, the plugin seems to work, but after a few seconds the vertical scroll bar periodically freezes, and the plugin makes outlook disconnect from my Exchange Server 2010 account. Then after a few more seconds it starts working again.
* Win 7 Pro 64 Bit Service Pack 1
* Outlook 2010 Small Business with all of latest Microsoft updates installed including all service packs
* Exchange Server 2010 email/calendar/contacts account
* Other outlook plugins running: Avira, Evernote
After reading this thread, I plan to uninstall the Todoist plugin until the 64 bit issue is fixed. Looks like you're almost there, because it is relatively stable on my computer, except for the periodic freezing when scrolling vertically through the task list.
Great plugin, by the way! I love your service! :-)
Please tell me - are you using the 64-bit version of Office or the 32-bit version? You've mentioned that you have a 64-bit Windows, but if Outlook is 32-bit, then the plugin should work fine.
Please try to disable other plugins from Outlook, uninstall our plugin through the Control Panel -> Programs and Features (listed as "OutlookTodoist") and install the new, pre-release update from: https://d2dq6e731uoz0t.cloudfront.net/82b87011c7a86df0809676bb96ebfa9b/as/OutlookTodoist.RC.exe and let us know if the issue persists.
Thank you so much. I'm sorry I misunderstood. I thought you were talking about 64-bit windows. My outlook is 32-bit, so maybe there's just a general glitch in my Outlook. Sorry for the confusion.
I have installed your new pre-release update and, so far, it works fine - no freezing, no crashing, no interfering with my Exchange account. Great work!
I just found a small glitch. After creating a task, if I click on the individual task's right-side menu and click "move to another project" the popup window with the list of projects does not have a scrollbar, so I cannot scroll down to select where to move the task. Please help!
I think I may have figured out the issue. I thought the project had disappeared because the name of it wasn't being displayed correctly by the plugin. I had an ampersand (&) in the name of one of my projects and the plugin was cutting off the & and the rest of the project name after the &. I went onto the todoist website and removed the ampersand and now it is working fine.
I have other projects where there is a space on each side of the ampersand and those show up fine. If the ampersand is right next to the adjoining characters then it disappears and the rest of the name of the project is cut off.
For example, the project name Salt&Pepper shows up as just Salt whereas Salt & Pepper (with spaces around ampersand) is displayed correctly.
This might be a small issue (I'm not sure how many people use ampersands in the project names), but I just wanted to highlight it for you.
Thanks for your help!
Regarding scrolling - even though the list of project doesn't have a scrollbar, the entire plugin window should have a scrolling bar on the right.
Regarding the & issue - please tell me:
- Can you reproduce this issue when going to https://todoist.com?mini=1 through a browser?
- If you uninstall the Outlook plugin through Programs and Features (listed as "OutlookTodoist") and install this new version: https://d2dq6e731uoz0t.cloudfront.net/82b87011c7a86df0809676bb96ebfa9b/as/OutlookTodoist.RC.exe does the issue persist?
Thanks for explaining the scrolling.
I could not recreate the issue on the website that you linked to in my browser. All ways of using the & worked.
The Outlook plugin version that you sent to me still gives the same issue with the & unfortunately. For now, I'm just making sure that I have spaces around any & that I use.
Maybe there are & symbols in the code relating to displaying project names, and the code is not registering the & as part of the text string but instead is thinking that it is part of the code?

I'm having a problem getting the outlook plugin to run
Here is my system info:
Windows 7 Enterprise (64 bit)
Here is the error from the COM Add-Ins dialog:
"Not Loaded. A runtime error occured during the loading of the COM Add-in."
Please confirm that you have .NET Framework 4 installed, as well as the Visual Studio 2010 Tools. If you re-install the Todoist for Outlook it will most likely ask you to install them if not installed. If it does not, you can download both from the Microsoft Site.
Visual Studio 2010 Tools:
.NET Framework 4:
