Your contacts and missing calendar information may be located in an Oulook PST file somewhere on your hard drive. Try this:
- Hold down the WINDOWS key and press R - the Run box should appear.
- Type CMD and press [enter]. The Command Prompt appears.
- Type dir *.pst /s and press [enter]. Take note of any files found.
- Type dir *.ost /s and press [enter]. Take note of any files found.
- Return to Outlook, and click File > Open and Export > Open Outlook Data File. Locate and open each file you noted above.
Hopefully, your contacts and calendar information are in one of these files!
No problem @Nickel11, I am glad you got this sorted!
The problem with duplicates is that you have multiple local copies on your computer. I don't know an easy way to eliminate the duplication, except manually.
Does anyone know an automated way to correct the duplication problem?
I believe my method of repair would be to have both the existing (blank contact and calender) as well as the old contact and calendar and drag and drop the information over. Once done I would manually delete the emails and info that was created in order to obtain the previous info that was lost.
That still deserves a "likes" robindp. Thanks for your reply and help.
By the way, back to the original post, was there a solution to multiple duplicate emails being sent with Outlook 2016 running Windows 10?
