After a bit more troubleshooting, I found when Outlook froze up, if I opened a File Explorer Window it would unfreeze Outlook and I could once again use. 

Another item I noticed was Outlook seemed to freeze when I used my mouse scroll wheel instead of the scroll bars on the previewed Excel document. I tried my hypothesis a couple times and sure enough, each time I scrolled the previewed Excel document with my mouse scroll wheel Outlook would freeze up.

Troubleshooting Steps I tried:

1. I installed the latest Office updates.
2. I opened Outlook in Safe Mode.
3. I made sure all Add-Ins were disabled. 
4. I ran Outlook as an Administrator
5. I disabled all Preview Handlers in Outlook and then re-enabled. 

The above troubleshooting steps did not resolve my issue. Here is the solution that finally worked for me. 

Step One: Open Windows 10 Settings (WinKey + I)

Step Two: Go to Devices > Mouse 

Step Three: Turn Off “Scroll inactive Windows when I hover over them” 

The Windows 10 feature “Scroll inactive Windows when I hover over them” is supposed to allow you to scroll through side-by-side Windows without having to click it to put focus on each Window. You can just hover over the Window and scroll.

Apparently, the “Scroll Inactive Windows When I Hover Over Them” doesn’t work well with Outlook.

Outlook Error Message

” Task “anybody@gmail.com” – Receiving reported error (0x800CCC90) : ‘Your incoming (POP3) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: – ERR Unable to retrieve rfc822msgid:xxxxxxxxxxxxx.

Every message in Gmail has a message ID assigned to it. You can find the Gmail Message ID by opening an email message and then clicking the down arrow beside the “Reply” arrow.

Gmail Message ID

More than likely the issue is that Outlook downloaded the message but Gmail says the message was not downloaded yet. This results in the error message referenced above. 

Here are the steps I used to resolve this issue. 

Step One: Log into Gmail on the web. 

Step Two: In the search box, in Gmail, search for the message referenced in your error message it should look similar to this: rfc822msgid:<31799347-9C90-4BBB-917D-CF95CCC21451>. Make sure to type the message ID exactly how it is referenced in the error message. Depending on the message ID you may need to add @domain after it like this: rfc822msgid:<54126538.1818.0@wordpress.com>  .

Rfc822msgid Search Result

If you typed everything correctly, you should find the offending email message. You can double check to make sure the email message ID matching the message ID of the error you are receiving in Outlook.

Step Three: Delete the offending email message from Gmail.

Step Four: Go back to Outlook and do a Send/Receive. The error message should disappear. If the error message does not disappear you can check out this older post about this issue or perhaps their are multiple messages that need cleared from Gmail. 

I hope this helps. Sound off in the comment section if it helped or if you have additional questions.

Troubleshooting: 

Step One: I found the documents were definitely being corrupted. I verified it wasn’t the recipient since the “sent” email attachment in the Outlook sent folder was also corrupted. When trying to open the attachment I got this message:  We’re sorry. We can’t open <doc name> because we found a problem with its contents.

Step Two: I found that the document would only become corrupted if the attachment was selected from the recent files list in Outlook 2016. When the file was attached by browsing to “This PC” and picking the file; files can through fine.

Through my troubleshooting I was convinced it was an add-in issue conflicting with the recent files list in Outlook. So through trial-n-error I found the offending add-in.

Resolution: I disabled Adobe’s Send and Track add-in in Outlook. I tried attaching a Word doc and an Adobe Attachment from the recent files list in Outlook and both files came through without a problem. Problem Solved!

To disable an add-in in Outlook go to File > Options > Add-ins > Manage Com Add-ins > Go and deselect the Adobe Send and Track add-in.

If this add-in isn’t present in your Outlook it is possible that another add-in is causing you grief. I would recommend disabling any third-party add-ins and then see if your issue is fixed. If your issue is fixed by disabling add-ins, enable one add-in at a time until you find the culprit.

If you find you font automatically changing on you, when replying to email messages, this is where you need to go to turn it off.

Step One: Open Outlook. Go to File > Options > Mail > Stationary and Fonts > Uncheck “Pick a new color when replying or forwarding”. Click OK.

That is all you need to do. I tested this and each time when the client replied her font and font color stayed to what she had set to default.

The specified module could not be found.

I had never seen this issue before. Here are some of the troubleshooting steps I went through. I thought it could be a virus or malware issue so I ran a scan till I knew that wasn’t the issue. I disable all the add-ins in Outlook that would affect performance, no difference. I created a new Outlook profile, same deal. I repaired Microsoft Office, didn’t fix the issue.

I decided to try disconnecting the mapped network drive. I disconnected the mapped network drive. I clicked “attach file” and it opened Windows Explorer without an issue. I went into the local documents and attached a file just fine. This confirmed in my mind that their had to be an issue between Outlook 2007 and the mapped network drive. I mapped the drive again and boom same error message and Outlook crashed as well.

I disconnected the network drive (R:\\sbs\folder1) and this time I mapped a different network folder (R:\\sbs\folder2). I clicked, attach file and this time I got no error message and Outlook didn’t crash! Now I was confused, one mapped network folder drive worked the other one didn’t. I tried accessing both network folders through Windows Explorer,(without going through Outlook). I could access both folders just fine. I was pretty much at wit’s end.

I called one of my colleagues about the issue. He found a .TVP file on the root of folder one. He removed the .TVP file. He then went into Outlook 2007 and tried attaching a file from that location. It worked. We copied the .TVP file back into that folder and the error came back and Outlook froze. Resolution: We took that .TVP file off the base of that folder and everything was back to normal!!

Some of the most difficult and irritating problems have such a simple fix. I believe this was probably a freak issue.  Apparently, their was a file association issue that was creating that error message and then Outlook would freeze and crash.

Special thanks to Kirby for helping me .

Step One: Make sure your .nk2 file is in the following folder: %appdata%\Microsoft\Outlook. Make sure the .nk2 file doesn’t have a .old file (profilename.nk2.old) extension after it. If it has the .old file extension after it delete it.

Step Two: Your .NK2 file must have the same name as your current Outlook 2013 profile to import correctly. To check if the names match:

Click on the Start Menu > Control Panel then click on User Accounts> Mail > Show Profiles. If they match you are ready to go to the next step. If your autocomplete file doesn’t match the name of your profile simply rename it to your current profile name.

Step Three: Click the Start button and then click Run. 

Step Four: In the open box, type the following command: outlook.exe /importnk2  and then click OK. This should import the .nk2 file into the Outlook 2013 profile.

I then opened Outlook and all of the autocomplete addresses and contacts were there! I hope this works for you as well.

They were running Microsoft Office 2007 so I went into the location where the data file was stored. The path for the data file in Windows Vista is  C:\Users\<username>\AppData\Local\Microsoft\Outlook . I copied the “Outlook.ost” to a flash drive.

I then took the computer off the domain and joined it to the new one. When I opened Microsoft Outlook it went through the “setup email account” wizard. I entered the

credentials for the email account. Once it started downloading mail I closed Outlook and browsed to the folder ( C:\Users\<username>\AppData\Local\Microsoft\Outlook) where the new “Outlook.ost” data file was stored. I copied the old data file, from the flash drive, into that folder. I then renamed the old data file to the same as the new data file. I opened Outlook again and entered the username and password and all the email was there.

A little while later our customer called and said the AutoComplete file was missing. So I went back into her old Windows profile. After a bunch of digging around in the old profile I found the .NK2 AutoComplete file. The file was not stored at the usual location but was stored at C:\Users\<username>\AppData\Roaming\Microsoft\Outlook\Office. I then copied the AutoComplete file into same folder (C:\Users\<username>\AppData\Roaming\Microsoft\Outlook\Office) in the new Windows profile. I renamed the old AutoComplete file (Outlook1.NK2) the same as the current file (Outlook.NK2). I then opened Outlook and all the AutoComplete addresses were there.

I recently ran into a situation where I was setting up email accounts on some new computers we had just installed.  The problem was I didn’t know the passwords for the email accounts I was setting up in Microsoft Outlook. That is when I discovered this tool that will reveal the email account passwords in Microsoft Outlook. Here are the steps to retrieve your password if your account was previously set up in Outlook. ( This also works in Windows Live Mail.) 

Go to your Control Panel> User Accounts>Mail > Show Profiles. Select the profile you want.

Then select Properties. Click on the email address that you need the password from and then select change. You should now be at the screen that shows your email account information including your password (with asterisks). Keep that window open.

Download this tool: asteriskkey

Run through the install wizard. 

You should eventually come up to the following screen.

Click the recover link.  Wait a couple seconds and this asterisk key tool will reveal your password.

Wasn’t that easy? This little tool has made my life so much easier. Let me know how you make out.
