The OTM file extension is a macro container used in various applications, but primarily associated with Microsoft Outlook. The file format was introduced in the mid-1990s with its default extension being .otm — standing for Outlook Macros or Outlook Macro Container. It stores global macros within a project, acting like a macro library for Outlook processes.
Technical Details
OTM files contain executable scripts written using Microsoft Visual Basic for Applications (VBA). It can hold code modules and xml parts, as well as pictures, forms and other embedded objects. Furthermore, OTM files may include text-based comments between each script, which are visible when opening the code in an editor such as Notepad. To open and edit the content of an OTM file the user must either use a capable text editor like Notepad++ or another programming software like Microsoft Visual Studio.
The main purpose of OTM files is to store scripts that speed up commonly used tasks in Outlook. These scripts run a series of actions, such as inserting and modifying date information in tasks or emails. Additionally, the script may sort data into tables or create custom tools. As macros have been around for decades and have been adopted by numerous programs and platforms like Excel, Word and Access, some related .otm file extensions commonly seen are .otm, .xlm, .docm, and .accde.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .OTM) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .OTM extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .OTM file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .OTM extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .OTM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .OTM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .OTM file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .OTM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .OTM file) will be extended to the maximum.
It is also good to check
- if the .OTM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
