MrMAPI x64 has stopped working

[Alex Melching]

Just recently have been receiving pop-up messages stating that MrMAPI x64 has stopped working.  Running Windows 10 Enterrpise (1703.15063.483) and Office 2016 (1706.8229.2086).  Pops up about every minute or so, a little annoying.  The issue started on 7/17/2017 out of the blue.  Anyone else running into this?

It's not an officially supported tool, but you can report the issue directly to the author here: https://github.com/stephenegriffin/mfcmapi/issues

There's at least one other crash report linked to the latest Office updates...

[#3]

If it's not an officially supported tool, how did it get installed?  I have installed no such tool referenced in the Github URL.  Does Microsoft package it with something else possibly?

[#4]

Well it's definitely not installed with Office. It's a separate download/install afaik, and not bundled with anything else, at least it wasnt last time I checked. Maybe they've bundled it with SaRA or similar, but I havent heard anything "official" on that.

I keep getting this message/popup running OFFCAT for Outlook 2016

[#6]

Same thing here. I get this prompt frequently when running OffCAT against an Outlook profile.

[#7]

same again - OffCAT, Win 7, and it also crashed Outlook

[#8]

I'm having the same problem on a computer running Windows Creators. MrMAPI x64 keeps closing and apparently keeps restarting when trying to run OffCAT! I presume this is why OffCAT keeps hanging. I'm having too many problems with Microsoft software.

[#9]

same here - trying to run OffCAT on Windows 10 Pro (1703.15063.540) against Outlook 2016 (1707.8326.2096 - Office 365).

OffCAT still seems to work, but MrMAPI x64 simply crashes again, each time you click 'Close program'

[#10]

seeing this as well... reached out to offcatsupp@microsoft.com but have received no response!

submitted as an issue in github here in the link below

[#11]

Same thing: OffCAT running against Office 365.

[#12]

Reran the scan on just Outlook: got the same error message at 10%. Scan then completed and had another message saying Office needed updating.

So I manually updated Office 2016, reran the scan on Outlook and no error message.

[#13]

mine is up to date and still seeing the issue. as see from the dates when this was first posted, this has been going on for a while. 

[#14]

I wanted to report that after updating Office, I was able to run an OffCAT scan of Outlook without a problem---at least so far.

[#15]

I just ran OFFCAT against Outlook 2016 as part of Office 365 and for once I didnt get the MrMAPI failure.

[#16]
