I heard that pst-files can grow as large as 50GB in size but also heard that issues will occur when it grows beyond 2GB.

My guess is that the difference is a technical limit versus a recommended limit.

Currently, my pst-file is reaching the 2GB and I wonder what I should do. Obviously, I do not want to run into issues but I prefer to keep my mailbox in a single pst-file rather than to create many little ones.

Which maximum pst-file size would you recommend?

When I try to add multiple attachments to my email I get the following message;

“You are attempting to attach too many files at once. Try reducing the number of files being attached.”

The total size of my attachments is well below the sending limit and I’m not aware of any limit to the amount of attachments that I may send out.

Why am I still getting this error upon attaching files?

For the past year, I’ve been archiving to a pst-file which I called “archive-2018.pst” which is also located in a “2018” folder of my Documents folder. I’ve now finished archiving everything of 2018 and want to start my 2019 archive.

How can I create a new archive and configure Outlook to archive to the “archive-2019.pst” file in the future?

I’ve been using Outlook since forever and I remember that I used to be able to create Desktop shortcuts to Outlook folders simply by dragging a folder out of Outlook and onto my Desktop (or any other folder in Explorer). This allowed me to quickly go to or open Outlook in a specific folder.

When I try do this now, my mouse pointer turns into a blocked shield.

Is it still possible to create Desktop shortcuts to specific Outlook folders in another way?

Over the years I’ve created a lot of contacts and due to merging and synching of data during that time, I sadly also have quite some duplicates.

I’m looking for a way to more easily recognize internal mail, i.e. mail coming from our @company.com domain.

I’ve been successful to do this for several external domains via Conditional Formatting (as described in Highlight mail from a specific domain) but when I try this for our own domain, it doesn’t work.

Is there a way to achieve this either via Conditional Formatting or a Search Folder for our internal mail as well?
